Free Interval Trainer Customer Insights

1. Unnecessary permissions and the explicit right to share my data? One star."blocking phone calls during excercise" is a pretty lousy excuse to ask for access to my location, contacts and ability to make phone calls.. you're a god damn stopwatch, you had one job - display a zero and when I press a button make the numbers go up until I press the button again.

2. Can get the features outlined in other apps that don't need permissions for my contacts, phone and location.

3. The app should be progressively enhanced by granting these permissions, not rendered unusable.Excellent app, only thing I'd like to ask for is to show the counter of the rounds while in rest, other than that it is nearly perfect.Great little app.

4. Exactly what I was looking forWhile it is explanable why the app asks location/phone calls/contacts permissions, I find it extremely annoying that the app won't work without giving them to it.

5. Not gonna trade these permissions for the features I'm not even plannig to useApp needs a lot of mandatory permissions not required for the functionality.

6. Only note would be the option to add intermittent resting periods but easy enough to get around that.Unnecessary permissions requested.

7. It refuses to work if you don't grant access to your address book and others.

8. Phone access.

9. Call blocking isn't even supported on the newest version of Android.

10. Badly implement or potentially dangerous.Simple. Easy to use.

11. Is it so hard?Great for timed trainings.
