The app for scoring and editing is awful. The scorecard is impossible to understand and get right. Not being able to go in after and adjust your score properly including putts especially is making everything I have bought from Garmin which is s70 watch, ct10 sensors and z30 range finder for a total of $2400 a total waste of money. Plus the premium Apple subscription I will cancel as it not worth the money. We buy these things to give us better insight to our game but instead we only get frustrated with its inaccuracy and lack of quality of the app. Come on really this really should be easy to use and easy to understand. Really someone take a look at Arcoss see how much better and easier it is to use. Editing is awesome and easy. Even it records and shows you every shot with an individual iron and you can take out your bad ones ir the shots that you know are not a full swing to give you proper distance accuracy with that particular club. This what we want a proper app not some Mickey Mouse one. I expect Garmin to be much better and not serve up this rubbish
