I wonder if anyone knows about Droid-ify. Whether it it a safe option, or better to stay away of it?

It showed up one day while I searched about why F-Droid was always so extremely slow to update and download... then trying Droid-ify, that was never a problem any more, it clearly had much better connectivity (or simply less users?)

it's a different client using same servers. fdroid official client is just super buggy.
