WatchCompanion - Live transit narrator

A live tracking app that announces transit stops for parents and kids

Problem

One developer built a Singapore MRT announcement app for his son, highlighting that parents need to explain which stop they're at and how many remain, but regular map apps don't speak in simple terms. Kids also enjoy the live announcement feel.

Solution

A minimalist transit tracker that after selecting a line, auto-locates and voice-announces the next stop, terminus, and transfer info. Supports custom language and volume, and even gamified progress (e.g., collecting stop badges).

Users

Parents traveling with young kids on metro/bus, children fascinated by public transport, and elderly needing clear stop announcements.

MVP

Support one or two cities' transit line data; GPS-based auto-location and voice announcement of next stop; simple kid-friendly UI; offline caching of core stop info.

Revenue

One-time $3.99 unlock for all cities, or per-city IAP; family sharing subscription at $1.99/month.

Why now

Transit data APIs are increasingly open, GPS and TTS on phones are mature, and indie devs can focus on niche audiences instead of building generic maps.
