Create a simple habit tracker inside Telegram so users do not need to install a separate app.
Result
The bot is live. Over 8,400 users joined in the first 2 months. The personalized push notification model achieved a 42% week-2 Retention Rate.
Water Tracker helps people count how much water they drink during the day. The user opens the Mini App inside Telegram, adds the amount in milliliters, and sees daily progress without a separate account or extra screens.
The main part of the project is not the tracker idea itself, but the flow inside Telegram. The bot has to open quickly, avoid confusing settings, and remind the user to drink water at the right time.
Built a Telegram bot and Mini App as one user flow.
Added milliliter-based tracking and daily progress.
Prepared reminders so the bot supports the habit instead of only storing numbers.
Kept the entry point short: open Telegram, tap a button, add water.
