Apps

Mobile apps, built to last.

12 React Native applications from the Stelr workbench — across finance, sport, health, reading and language. Every one ships with a privacy policy written from its actual schema, and 5 of them never transmit your data at all.

Sports

Beta

Fixture

Local sports competitions, properly run.

Fixtures, live scoring, player auctions and the ledger — cricket, football, tennis, badminton, chess and table tennis in one app. 56 screens, zero type errors.

Health & Fitness

Beta

Stride

Run tracking that earns the location permission.

GPS run tracking with live route mapping, analytics and a social feed — built so that the most sensitive permission it asks for is used for exactly one purpose.

Finance

Release candidate

Oats

Personal finance that never leaves the device.

A fully offline personal finance tracker. No backend, no network calls, no cloud sync — every record lives in a local SQLite database, and the only copy that ever leaves the device is a backup you export yourself.

Productivity

Release candidate

Wraith Tasks

A todo app that shows its work.

A smart todo app whose intelligence is a word count — instant, private, and testable. Natural-language capture, a focus queue that explains its own ranking, and honest recurrence. Everything runs on device.

Finance

Beta

Ledger & Co.

Bank alerts go in, a plan comes out.

A monthly money app for a salaried person in India. Paste the bank alerts you already get, and the month organises itself into a plan. One codebase runs as an installable web app, an Android app and an iOS app.

Health & Fitness

Beta

Grit

Workouts, nutrition and the days you showed up.

A training log covering routines, sets, nutrition, body measurements and gym attendance — with barcode scanning that never uploads an image and partner features that share strictly less than you'd expect.

Finance · Education

Beta

Cambium

Trade. Learn. Evolve.

A financial markets simulator where people trade with virtual money — and external AI models and algorithms trade the same book via API, measured side by side. A training and benchmarking environment, not a real trading app.

Education

Podium

Argue with an article. Out loud.

A speaking-practice app: read an article, get assigned a stance, and argue it aloud against the clock. Your speech is transcribed on-device by Whisper — the audio never leaves the phone.

React NativeExpo SDK 56TypeScriptwhisper.rn

Health & Lifestyle

Beta

Habits & Hydras

Life gamification with an XP engine you can edit.

A habit and activity tracker that awards experience points for what you log — fitness, study, reading, nutrition, sleep, mindfulness — with guilds, quests, challenges and an XP rulebook you can open and change.

React NativeExpo SDK 56NativeWindTypeScript

Books & Reading

In development

Folio

A reading log that respects the shelf.

A personal reading tracker with an ISBN scanner, a Goodreads importer and reading-goal tracking — backed by a local SQLite library that works with the network off.

Sports

In development

Rally

A score organiser for the games you actually play.

Schedule a fixture, score it live, and let the ledger build itself — across cricket, football, table tennis, badminton, tennis, chess, basketball and volleyball.

Travel

In development

Drift

A passport for the places you actually went.

A travel journal that turns logged places into a passport, a world map and a year in review — without asking for an account or a location permission.
