### 5/5 — Great App .. 5 stars download now!

*2026-09-26, version 8.16*

Man this app is almost perfect and it’s in the same tier as Actions for Shortcuts App. Only issue is it doesn’t support custom .guff file import for local model use making it api dependent which sucks cus it’s so powerful and looks so good should at least use Apple’s models.

### 5/5 — Simply a game changer

*2026-09-20*

I wish I could sum up all the words necessary to give this app its proper due, but unfortunately, I am not blessed with such excellent vocabulary. I can’t believe I wasted so much money on so many apps when this one comes in a fraction of the price and does 10 times more. It’s simply amazing. I can’t believe it.. i’m a plus member which is only five dollars and they have a pro tier which is 20 and I can’t even fathom how much that does. I can’t wait to find out,worth every penny.
