Army for Life — 0 to 40,000+ users
Amal Jose
Overview
Army for Life is a mobile app built with Jesus Youth that lets people spiritually "adopt" an unborn baby and pray for them daily. I led product and engineering as we took it from a small proof-of-concept to a native app used by 40,000+ people.
Starting lean
We began with a minimal web version and tested it with around 50 users in one region — built with React and browser local storage, with analytics to learn how people actually used it.

Early learnings shaped everything that followed: prayer progress was lost when users switched devices, people missed prayers without reminders, and having to open a browser added friction.
Key product decisions
Native over PWA: iOS didn't support PWA notifications, and WhatsApp's API was too costly to scale a free app — so we went native and used free Firebase Cloud Messaging for daily reminders.
Offline-first architecture: users can pray even with no connection, and changes sync once they're back online. No error states in a moment meant for reflection.
Optional signup: no forced onboarding — data backs up to the server whenever a user chooses to sign in.
A warm, personal touch
Each adopted baby can be named, and users receive a unique hand-drawn image plus milestone rewards as they progress — small details that made the experience feel personal.

Engineering care
Most features revolved around dates and time — like a "baby is born" banner after a full pregnancy period. Rather than wait 280 days to test, we wrote unit tests that simulate time to guarantee the logic was correct.
Result
From idea to 40,000+ users, with a stable, low-maintenance app and an experience people love returning to.
"Pentagon Studio helped us go from idea to 40K+ users with a lean, efficient approach — smooth scaling and long-term stability." — Dino Paul, Army for Life
