A shared plan instead of endless discussion
A prototype helps friends choose plans through rooms, cards and voting. It lets the team test group decision mechanics before investing in a server-backed launch.
Project materialWho it is for
Consumer product teams, leisure services and Telegram Mini App builders.
What it enables
The core journey is complete locally: create a room, evaluate options and reach a plan. Product rules are separate from the interface and covered by tests. This supports hypothesis testing and pilot planning, not retention claims or a live multi-user service.
Help a group of friends move from endless options to one shared plan.
- The prototype must clearly separate working mechanics from the missing backend.
- The reward economy needs one source of truth and explicit assumptions.
- Telegram initData cannot be trusted without server-side validation.
- Venue feed, map states, friends and a full room flow through the final plan.
- Isolated domain modules for voting, coins, streaks and partner rules.
- Interactive economics model and a product-mechanics register.
