hmm my guess is that they may have taken it off the iOS store? it was an alpha release so it could have been taken down if it was too buggy. im not 100% sure about that though.
it could possibly have something to do with the older iphone.
id reachout to @steepshot on here or through there website https://steepshot.io/ andlet them know what happened and see what they say.
im not affiliated with them or anything so i can only make guesses. the android version is working perfectly fine for me.
thanks man, I will do, appreciate your help
no problem! hope you get it working! its a cool little app to have on your phone.
