One prepaid meter.
Everyone knows who tops up next.
SplitBill is for flats that share a single prepaid electricity meter. Log each recharge, split cost by actual usage, and keep balances straight across roommates — without a spreadsheet or a group chat argument.
- No account — data stays on your phone
- Optional Room ID sync for multiple devices
- Works fully offline after setup
What you actually do
Three screens, repeated after every meter top-up.
Log a top-up
Record meter readings and the amount paid after each recharge.
Review history
Track monthly usage and fix a bad entry if someone mistyped.
Built for the meter room, not the app store
Practical features for shared prepaid setups.
Room + members
Name the flat, add everyone on the meter, pick yourself on each phone.
Usage-based split
Cost follows meter deltas — not an even split every time.
Room ID sync
Share one ID so every phone sees the same logs. Cloud sync is optional.
Local backups
Export JSON anytime. Add a password if you want the file encrypted.
Home widget
Glance at balances from your launcher without opening the app.
Open source
Read the code, build it yourself, no vendor lock-in. GitHub.
