I purchased a new bike recently, my old one was 18 years old. The new bike had disc brakes and other upgraded parts that I had never worked with before. I needed a good reference app to bring me up to speed with what I needed to do to. After going thru another popular bike repair app I found I still needed a better understanding on what the parts looked like and how they went together. This app provided that. The app also gave a heads up on what to look out for by mentioning common mistakes made by people like myself. There is also a safety inspection guide and a guide to doing a yearly overhaul.
Thank you to the author/s of this great app.
