I've never used anything sync before a few hours ago (prior was in bacon reader for 8 years but it doesn't look like they're interested in making another app), I've been using it for 2 of the last 3 hours, no obvious phone heat at all on my s22+ that likes to heat randomly. So maybe sync fixed my phone heating issues? XD to each our own, but I'm pretty sold so far on sync, and their "ads" aren't showing up as anything except blank spaces (this will undoubtedly be fixed). I think I got bacon reader for a steal at 2$ (and whatever personal information they were harvesting) and I think sync for 1 time payment of 20$will yield similar happiness.
