The Problem

What I was solving

A friend kept forgetting pills. Standard phone alarms dont help — you mute them and forget. Apps usually ask you to install something yet another thing. The trick isnt reminding once; it is being persistent without being annoying, and keeping a real history so the doctor sees whats taken and whats missed.

My Approach

How I built it

Telegram Mini App — no install, users already have Telegram open. React frontend lives inside Telegrams WebView, Python FastAPI backend exposes the API, aiogram bot handles push notifications with configurable retry (5/15/30 min) until marked taken. Six Docker services: frontend, backend, bot, PostgreSQL, Redis, nginx. Per-user timezone support because reminding at 3am is worse than not reminding. Admin dashboard shows DAU, active users, and ban controls for abuse.

Tech choices

Telegram Mini App— Zero install friction. Users already have Telegram — its an open WebView with auth baked in, no sign-up flow to abandon.
aiogram + FastAPI— Async Python everywhere — bot and API share models and DB without a second runtime. Scheduled reminders live in the same process as the API.
Redis— Reminder queue and rate-limiter in one store. A pill due at 10:00 becomes a scheduled Redis job — durable even if the bot process restarts.

Outcome

What came out of it

One-click entry via Telegram — no app install, no new account, no password to forget. Retry logic catches the "I will take it in 5 minutes" excuse because the bot keeps pushing until you actually mark the pill as taken. Daily checklist and intake history become a readable log for the doctor. Admin dashboard makes abuse detection a 30-second scan.
