How We Built a Church App in 10 Days Using AI

Written by Nandini Sharma | Apr 24, 2026 11:18:33 AM

At Optiblack, we don’t believe in overbuilding.

We believe in building fast, validating faster, and iterating based on real usage.

Recently, we worked on an early version of FaithReach — an AI-powered app designed for church growth, spiritual habits, and evangelism.

Instead of a traditional build cycle, we shipped the first version in just 10 days using:

  • Figma AI for design
  • Cursor for development

 

The Idea

FaithReach is built as:

An AI-powered system to help individuals grow in faith and help churches scale engagement

It combines:

  • Prayer & habit tracking
  • Bible reading & devotionals
  • Church attendance flows
  • Sermon insights
  • AI-powered evangelism

Our Approach

We kept it simple:

Design fast → Build fast → Test in market

1. Figma AI for Design

We used Figma AI to:

  • Generate UI flows quickly
  • Maintain a consistent design system
  • Build key journeys like onboarding, prayer, and Bible modules

No pixel-perfect obsession — just clean, usable design.

2. Cursor for Development

With Cursor, we:

  • Converted designs to code rapidly
  • Built full flows without heavy setup
  • Focused on functionality over perfection

What We Shipped in 10 Days

The first build included:

  • Onboarding & authentication
  • Prayer Journal
  • Bible & devotional module
  • Growth tracking
  • Church attendance
  • Evangelism toolkit
  • Basic AI assistant

👉 Not polished
👉 But fully usable

Why This Works for MVPs

This approach helps us:

  • Move fast — days, not months
  • Reduce cost — minimal upfront investment
  • Validate early — real user feedback
  • Iterate quickly — continuous improvements

The Trade-offs

Of course, there are trade-offs:

  • Not production-grade code
  • Some UX gaps
  • Limited scalability initially

But for an MVP, that’s acceptable.

The Optiblack Way

For early-stage products, we optimize for one thing:

Speed of learning > Perfection

Once the concept is validated, we:

  • Refine UX
  • Improve architecture
  • Scale the product properly

Final Thought

  • AI tools like Figma AI and Cursor are not just productivity hacks.
  • They’re execution accelerators — especially in the 0 → 1 phase.
  • And for FaithReach, they helped us go from idea to product in 10 days.
  • If you’re building an MVP and want to move fast — this approach works.
