Had been working great until an hour ago. I have the notification that I can watch an add for so many minutes. As so as I click to watch the ad, I get kicked out of the program. I tried turning my phone all the way off. Then turn it back on - same problem. Very frustrating. Update: working again. Don't know how or why. Chalking it up to a glitch in the matrix.

In the latest version DeFit, if you don't watch ADs, you are still able to use DeFit without any problem. Please see (English) for troubleshooting. If you need any help, please send your screenshots of DeFit to

It works, but there could be some quality of life improvements, so that we aren't doing our own math and keeping track of the defit sync start and end times. For example, it could have a setting to stop walking after a certain distance or time has been covered, plus a little random extra. This would help us to get buddy hearts or eggs hatched. Or at least tell us when was the start time, and how much distance has been clocked since then.

I wanted to give this five stars because it worked perfectly for me for a long time, but recently it stopped offering ads. Now I mostly get Ad N/A: 3. Every now and then if I minimize and bring it back up it will offer one, but 95% of the time it doesn't. Tried uninstalling and reinstalling. Wondering if it might have been a Samsung update or something 🤷. It's still great, though, and you can click to get minutes in sets of 60 up to a total of 240 each time they run fairly low.
