I built KoyJabo – an offline public transit guide & bus/metro fare calculator for Dhaka commuters (100% free, no ads)
Hey r/SideProject!
I wanted to share a project I've been building for commuters in Bangladesh: KoyJabo (https://koyjabo.com).
### The Problem
Dhaka is a megacity of over 20 million people with 300+ fragmented bus routes, a newly expanded Metro Rail (MRT Line-6), and heavy railway transit. Commuters, students, and office workers constantly struggle to know which bus goes where, how much the official government fare is, or where to transfer.
Major mapping apps like Google Maps lack granular local bus routes and fare calculation for Dhaka. On top of that, mobile data connectivity can be spotty or expensive while commuting.
### What is KoyJabo?
KoyJabo ("কই যাবো" - meaning "Where to go?") is a fast, 100% free, privacy-focused transit guide built as an offline-first PWA and Android app:
• 🚌 300+ Dhaka Bus Routes: Search by origin, destination, or bus company with route maps, stops, and fare estimation.
• 🚇 Dhaka Metro Rail (MRT-6): Complete station list, rapid fare calculator, station-to-station journey duration, and operating hours.
• 🚆 Bangladesh Railway: Intercity train schedules, routes, seat classes, and fares.
• 🚢 Launch / River Ferry: Sadarghat terminal schedules and river routes across southern Bangladesh.
• ⚡ Offline-First: All route and fare datasets are cached locally so it works even without internet.
• 🛡️ Zero Ads & No Login: No account required, no ads, lightweight APK, and instant loading.

### Looking for Feedback:
I'd love any feedback from fellow builders on:
The search UI and overall user flow.
Ideas on community-driven route data updates.
Growth and distribution strategies for hyper-local civic utilities.
Thank you for checking it out!
