### 1/5 — Wants me to purchase

*2020-05-06*

This is one of the worst subtitle apps. When I tired to use it I was brought back time and time again to buy a subscription. Why would I buy an app that doesn't even work free first? 

Do not waste your time with this one.

### 1/5 — Worst.

*2020-04-11*

I would scroll through my videos to edit and it would freeze and glitch me out and when i didn’t touch anything to purchase it would say “in app purchases not allowed” and “error plz try purchasing again” bro i didn’t even do a thing and definitely did not ask to purchase anything. 😑

### 1/5 — Very confusing :/

### 1/5 — Ugh

*2019-11-07*
