About BikeHist
How long has actually held the chain? Is the front tyre already two or three years old? And what's the mileage? With the app you simple record these maintenance activities and thus have an overview of your bikes. The data can be ex-/imported as a text file, so that a backup is possible, for example, on Google Drive or on the local computer.
This app is free of advertisements. You can support the development by suggestions for improvement. Many thanks!
