Mile Keeper records the odometer, works out the charge in LKR and gives you a clean PDF bill to send on WhatsApp. It runs fully offline on your Android phone.

What it does

Built for an owner renting out one car. It does a few things and does them properly.

Handover to return

Save each rental with the customer's name, phone, destination and notes.

Odometer by photo

Type the reading or take a photo. The app suggests the number and you confirm it. Fuel gauge photos are optional.

Bill in LKR

Set your daily price, included km per day and rate per extra km. It works out days, extra km, total and balance.

PDF bills in one tap

Share a clean PDF with your name and number on it through WhatsApp, SMS or any app.

Payments and history

Record payments, see what is still owed and look back through each month.

Private by design

Optional fingerprint or screen lock. Encrypted backups with a recovery phrase that only you hold.

How it works

Three steps for each rental.

Hand over the car

Enter the customer details and the starting odometer.

Record the return

Add the return reading and any payment received.

Send the bill

Check the total, then share the PDF with your customer.

How to install

The app is installed straight from the file, not from Play Store, so Android asks you to allow it once.

  1. Tap the download button and wait for the file to finish.
  2. Open the file. If Android blocks it, tap Settings and allow installs from your browser.
  3. Go back and tap Install.
  4. Open Mile Keeper, add your name under Settings, and set your daily rate.

Try it on your next rental.
