## What is Jitensha?

"When did I last oil that chain?" A notebook that takes on the record and the timing of bicycle maintenance.

- Keeping the record
- Chain oiling, tyres, brakes, cleaning, each kept as its own item
- Press "done" and the next rough date is set for you

- A word when it is about time
- Based on the interval you registered, you are told quietly when it comes round
- The rough guides are shown with their source, and you can edit them yourself

- Made to be safe to use
- Everything stays inside this device only (nothing is sent anywhere)
- No ads
- This app does not judge whether a bicycle is in good order. If something concerns you, please take it to a bike shop
- One bicycle with every feature is free (more bicycles and CSV export are a one-time purchase)

A notebook for staying with a bicycle a long time, at your own pace.
