Digital Mandir
An Android devotional app that turns daily chanting into a habit — a digital mala for mantra jaap, a community leaderboard, and push-notification reminders, all managed through a custom admin panel.
The Challenge
Understanding client pain points
Daily mantra chanting is a deeply personal practice, but keeping count on a physical mala and staying consistent day after day is hard. The client wanted an Android app that made jaap effortless and motivating: an accurate digital mala to count chants, a sense of community and friendly competition to keep devotees coming back, and gentle daily nudges so the practice becomes a routine. The challenge was delivering a precise, satisfying counting experience that never miscounts, a fair real-time leaderboard, and reliable scheduled reminders — all on a single Expo codebase shipped to the Google Play Store, with non-technical staff able to manage content and users behind the scenes.
The Solution
Engineering a modern solution
We built Digital Mandir as an Android-first React Native (Expo) app backed by a Node.js and MongoDB API, with a dedicated React admin panel. The centerpiece is a digital mala for mantra jaap — a tactile, responsive counter that tracks each chant and completed mala (108 beads) with haptic feedback. A community leaderboard ranks devotees by their jaap counts to drive motivation and daily return visits, while Firebase Cloud Messaging delivers personalized daily reminders so users never break their streak. The admin panel lets the client manage mantras, users, and leaderboard data and trigger push campaigns without touching code. We shipped the entire experience from one Expo codebase to the Play Store.
Shared Architecture, Instantaneous Synchronization
Digital Mandir pairs an Android consumer app with an internal admin dashboard, sharing one API so the team can manage mantras, users, leaderboards, and notifications behind the scenes.
The Digital Mandir Android app, built with React Native and Expo, makes daily chanting effortless — a precise digital mala for mantra jaap with haptic feedback, a community leaderboard that turns devotion into friendly motivation, and scheduled push reminders that keep the practice a daily habit. Shipped from a single Expo codebase to the Google Play Store and tuned to run smoothly on everyday Android devices.

The Technology Stack
Challenges & Engineering Decisions
A mala counter must never miscount or feel laggy, even during rapid tapping. We built the counter on local state with debounced, optimistic updates and haptic feedback, syncing totals to the backend in the background so the count stays instant and reliable while progress is never lost.
