About the Client
City Revival Church — Where Faith Meets Technology
City Revival Church is a vibrant Christian community built on a commitment to deep, scripture-rooted discipleship. Unlike churches focused primarily on Sunday attendance, City Revival invests heavily in helping their congregation develop a personal, daily relationship with the Bible — studying scripture systematically, in context, with a framework that builds lasting spiritual maturity over time.
The church’s approach to Bible study is encapsulated in the name Solid Food — drawn from Hebrews 5:14, which speaks of mature believers who, through constant practice, have trained themselves to understand God’s word deeply. This isn’t casual devotional reading. It’s structured, intentional, progressive study — and it needed a digital platform to match.
City Revival approached Smitiv with a clear brief: build a mobile app that would serve as a daily spiritual companion for their congregation — accessible, beautifully designed, and rooted in their specific theology and Bible study methodology. The result is the Solid Food app, available on the App Store and continuously maintained since April 2022.
“
But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.
— Hebrews 5:14 · The theological foundation and name behind the app
Active Congregation Members
Members who attend regularly and want to deepen their faith between Sunday services through structured, daily Bible engagement guided by the church’s teaching framework.
New & Growing Believers
Newer Christians who want to learn how to study the Bible properly — not just read it. The app’s systematic method provides scaffolding for lifelong biblical literacy.
Distributed Faith Communities
Members who may not be physically present every week — whether travelling, living abroad, or in different time zones — who want to stay connected to the church’s study programme.
The Challenge
Discipleship That Goes Beyond Sunday
City Revival Church faces a challenge that is common to faith communities worldwide: the gap between Sunday engagement and weekday spiritual growth. Without a structured, accessible, and well-designed digital tool, daily Bible study was inconsistent, scattered across paper notes and generic Bible apps, and difficult to maintain as a sustainable habit.
-
No structured daily study framework. Without a guided method, members were left to their own devices for daily Bible engagement — leading to inconsistency, shallow reading, and a sense of not knowing where to start or how to study meaningfully.
-
Generic Bible apps lacked the church’s methodology. Off-the-shelf apps like YouVersion offer reading plans but not the specific contextual, observational, and applicational framework that defines City Revival’s approach to Scripture. The church’s unique method needed its own home.
-
No personal devotion journalling tool. Members had no integrated way to record their personal reflections and notes alongside the passage they were studying. Paper notebooks were disconnected, hard to search, and easy to abandon.
-
No study accountability or reminders. Daily Bible study is a habit — and habits need prompts. Without automated reminders tied to the study content, members would forget or deprioritise their daily devotion during busy periods.
-
No direct church-to-congregation digital channel. Beyond WhatsApp groups and email, the church had no dedicated in-app channel to push announcements, sermon notes, banner updates, or community news to their members.
-
Privacy-first congregation needs went unaddressed. Church members are particularly sensitive about their data. A custom solution would allow the church to build an app that collects zero personal data — a deliberate stance that reflects the community’s values of trust and integrity.
The Smitiv Answer
Build a purpose-designed iOS app that embodies City Revival’s specific Bible study methodology — structured around Background, Observation, Truth, and Application — and serves as a daily companion for every member of the congregation. Not a generic devotional app. A platform built for this community’s specific spiritual journey.
Core Objective
Create a daily digital touchpoint that keeps members engaged with scripture in a structured, personally meaningful way between Sunday services. Build the habit of daily study through excellent UX, smart reminders, and a platform that actually feels like it understands the spiritual journey.
Privacy as a Design Principle
From day one, the app was designed to collect zero user data. No tracking, no analytics on personal study behaviour, no data sharing with third parties. The Solid Food app’s privacy stance is one of its defining features — and a deliberate reflection of City Revival Church’s values.
The Bible Study Method
Built Around a Proven Framework
At the heart of the Solid Food app is a systematic Bible study method that City Revival Church has refined over years of discipleship ministry. Every passage in the app follows the same four-step framework — providing context, analytical depth, doctrinal grounding, and practical application. This structure is what separates Solid Food from a reading plan.
Step 01
Background
Every passage opens with contextual background — the historical setting, author’s purpose, audience, and cultural context of the text. This grounds the reader in the world of the original audience and prevents misinterpretation through anachronistic reading.
Step 02
Observation
Members are guided to look carefully at what the text actually says — its structure, key words, literary devices, and connections to surrounding passages. This step trains the discipline of seeing before interpreting, a foundational skill in serious Bible study.
Step 03
Truth
The doctrinal and theological principles drawn from the passage — what the text teaches about God, humanity, sin, salvation, and the Christian life. This step connects individual passages to the broader arc of biblical theology and City Revival’s teaching tradition.
Step 04
Application
The practical dimension — how the truth of the passage changes the way members think, speak, relate, work, and live. Application questions prompt personal reflection and connect scripture to real, everyday situations rather than leaving truth abstract and theological.
What We Built
Five Features Built for Daily Discipleship
Every feature in the Solid Food app was designed to remove friction from the daily study habit and deepen the personal engagement each member has with scripture. Here’s what Smitiv delivered — and why each component matters for a church community.
Feature 01
Systematic Bible Study Engine
The core of the app. Every passage is structured using City Revival’s four-step framework: Background, Observation, Truth, and Application. Members move through each step sequentially, developing biblical literacy progressively. The study library contains 240+ passages covering multiple books of the Bible, curated and authored by City Revival’s teaching team directly within the app’s CMS. As the church creates new content, it appears in the app immediately — no app update required.
Feature 02
Personal Devotion Notes
An integrated journalling feature that allows members to write and save personal notes on each passage they study. Notes are stored locally on the device, keeping the data private and accessible offline. This creates a growing personal library of scripture reflections — a spiritual journal that documents the member’s growth over months and years of daily study. Users can browse their notes chronologically or by book of the Bible, making it easy to revisit insights.
Feature 03
Smart Daily Reminders
Fully customisable push notification reminders prompt members to return to their study at a time that works for their schedule. Users can set multiple reminders for different days, choose between morning devotion, lunchtime study, or evening reflection, and personalise the reminder message. Reminders can be individually managed and deleted. This feature has been identified by City Revival’s leadership as one of the most important habit-forming mechanics in the app, with members crediting it with maintaining their daily study consistency.
Feature 04
Favourites & Bookmarking
Members can star passages that particularly resonate — creating a personal curated library within the app. Favourited passages are immediately accessible from a dedicated tab, allowing members to revisit meaningful studies without searching through the full library. This feature supports the reflective, devotional use of the app: a member can return to a passage that spoke to them during a difficult season and re-engage with it from a new vantage point.
Feature 05
Church Banners & Announcements
A church administration capability that allows City Revival’s team to push banner content and announcements directly to the app’s home screen — without requiring an app update. This is used for upcoming sermon series, community events, new study content launches, and church-wide campaigns. The banner system gives City Revival a direct, in-app communication channel with their entire congregation — reaching members in the context of their daily study rather than competing for attention in a crowded email inbox.
Feature 06
Reading Streaks & Progress Tracking
A motivation and accountability layer that shows members their daily study streak — how many consecutive days they have maintained their devotion practice. Progress is tracked per Bible book, showing percentage completion of each study series and allowing members to see their journey at a glance. Streak visibility creates a gentle, non-gamified accountability mechanism that encourages consistency without pressure — aligning with the app’s supportive, grace-oriented design philosophy.
Our Process
How Smitiv Built It
Building for a faith community requires a unique sensitivity — to theology, to community dynamics, and to the specific spiritual outcomes the client is trying to achieve. Our process for City Revival was structured around understanding the mission before designing the product.
Phase 01
Discovery — Understanding the Discipleship Mission
Before writing a line of code, we spent significant time understanding City Revival’s specific approach to Bible study. This was not a generic app brief — it was a theological and pedagogical brief. We needed to understand the four-step study framework in depth, how the church created and structured content, what spiritual outcomes they wanted for their congregation, and what success looked like at a community level. This discovery phase produced a clear product specification rooted in the church’s actual discipleship values — not generic best practice from app development templates.
Phase 02
Design — Calm, Focused, Scripture-Centred
The design philosophy for Solid Food was deliberate restraint. The UI needed to serve the scripture — not compete with it. Typography was selected for extended reading comfort. Colour was used to differentiate the four study steps without distracting from the text. The note-taking interface was designed to feel like a journal, not a form. Dark mode support was built in from the start, recognising that many members use the app for early morning or late evening devotions. The result is an app that feels peaceful, focused, and appropriate to the act of study and reflection.
Phase 03
Development — Native iOS, Privacy by Design
The Solid Food app was built natively on iOS for optimal performance and platform alignment. The privacy-first architecture was designed from the ground up: zero user data collection, local storage for personal notes and favourites, no analytics SDK, no third-party tracking libraries. The content management system — which allows City Revival’s team to create, edit, and publish study content independently — was built as a secure web interface that integrates directly with the app in real time. The app was submitted to Apple’s App Store in April 2022 and passed review on the first submission.
Phase 04
Iteration — 20+ Updates Since Launch
Since the v1.0 launch in April 2022, Smitiv has shipped 20+ updates to the Solid Food app. Key milestones include: devotion notes feature added (v1.3), reminder management improvements (v1.6–v1.9), complete UI redesign of the home screen (v1.5), account deletion capability (v1.4), the reading streak and progress tracking system (v4.6), and performance overhauls in 2024 and 2025 (v4.6–v4.9). Each update reflects feedback from the congregation and City Revival’s growing vision for the platform. The partnership is ongoing and active.
Technology
The Right Stack for a Privacy-First Platform
The Solid Food app was architected around a core principle: the congregation’s spiritual journey is private. The technology choices reflect this — local storage for personal data, no tracking SDKs, and a minimal data footprint that aligns with Apple’s strictest privacy guidelines.

Who This Is For
Is a Custom Church App Right for You?
The Solid Food app demonstrates the power of custom software for faith communities. But who exactly should be considering a dedicated digital platform like this? The answer is broader than most ministry leaders expect.
Churches & Local Congregations
Any church with a discipleship focus, a teaching methodology, or a congregation it wants to engage daily — not just on Sundays. A custom app creates a ministry touchpoint that reaches members in their daily life.
Bible Colleges & Seminaries
Educational institutions teaching systematic theology or biblical studies can use a custom platform to deliver course content, track student progress, and create a structured digital study environment.
Ministry Organisations
Para-church organisations, missions bodies, and discipleship networks that want to scale their content and methodology digitally — reaching members and supporters beyond their geographic footprint.
Authors & Bible Teachers
Individuals who have developed a Bible study methodology or devotional framework and want to distribute it as a digital product — building a community around their teaching content.
Cell Groups & Small Ministries
Smaller faith communities that want a dedicated study platform without the cost of enterprise software — Smitiv’s fixed-cost model makes custom development accessible at any scale.
Multi-Site & International Churches
Churches with members across multiple locations or countries who want to create a unified digital experience that keeps the entire community connected to the same teaching content.

What We Learned
Key Lessons from Building for Faith Communities
Building the Solid Food app gave Smitiv deep insight into what makes digital discipleship tools succeed — and what causes them to fail. These lessons now inform every faith and education project we take on.
01
Method Matters More Than Content Volume
The most common mistake in Bible app development is treating the problem as a content delivery problem. Solid Food succeeds not because it has the most passages, but because each passage follows a consistent, pedagogically sound framework. Users know what to expect with every study — and that predictability builds the habit. Method creates structure; structure creates habit; habit creates growth.
02
Privacy is a Feature, Not a Compliance Checkbox
City Revival’s decision to collect zero user data was initially pragmatic — but it became one of the most meaningful aspects of the product for their congregation. In a faith context, trust is foundational. An app that explicitly collects no data, tracks no behaviour, and shares no information with third parties signals a deep respect for the spiritual privacy of the individual. This is something no SaaS app can match by default.
03
Reminders are the Most Underrated Feature in Any Habit App
Daily Bible study is a discipline — and disciplines require external triggers until they become truly habitual. The reminder feature in Solid Food is simple by design: pick a time, set an alert. But its impact on daily engagement has been profound. Members consistently report that the reminder is what brings them back on days when life gets busy. Never underestimate the UX impact of a well-timed, contextually appropriate notification.
04
Design for the Spiritual State of the User
People use the Solid Food app in moments of quiet — early mornings, late evenings, during lunch breaks, in transitional moments of the day. The UI was designed to match this state: calm, uncluttered, unhurried. An app designed for the spiritual moment performs differently — and better — than one that looks like a productivity tool with a Bible attached. Context-sensitive design is essential in faith tech.
05
Empower the Church to Own Their Content
One of the best decisions made during development was building a CMS that allows City Revival’s team to create and publish new study content independently — without needing Smitiv’s involvement. This gives the church operational sovereignty over their own platform. The app grows with the ministry’s teaching calendar, not with our development capacity. Every faith platform should be designed with this independence in mind.
06
Technology Serves Theology — Never the Reverse
The most important lesson from the Solid Food project is a philosophical one: technology for faith communities must be built to serve the community’s theological vision, not to impose technological assumptions on it. Every feature, every interaction, every design decision was filtered through the question: does this serve the spiritual growth of the person using it? When technology is built with this intentionality, it becomes a genuine ministry tool rather than a distraction.
