AI SLOP. Don’t waste your money.

Worst peptide app on the AppStore and there’s not even a free trial and it forces you to pay upfront without even trying anything.

Do not recommend, check out other peptide apps instead!!

BILLS U AND WONT REFUND

I ACCIDENTALLY paid for a yearly subscription. Once I noticed i IMMEDIATELY SAME DAY cancelled it but yet have to receive my MONEY BACK. It’s so frustrating and very upsetting!!

Not user friendly

It’s a great concept, but it’s not easy to use. Once I entered my dose, I could never find where to change it. It wasn’t subtracting my dose from my supply, and it never increased the estimated amount in my system. It also won’t let me log a dose in mg if my supply is entered in units. Has a few things to fix, but I’m sure they’re in the works.

BEST IN MARKET

This has been game changing. No more forgotten doses. No more guessing on when I need to refill my supply. It’s my second brain for when I forget everything
