Rubbish. It freezes and if you restart it by reinstalling, the premium credits are gone All told, I lost 3000 character credits were gone for nothing in return. After posting, some credits were returned but not all, the same issued happened and again credits lost. It would be better if credits are taken only once a recording is recorded Seriously, you need to fix this because it is so frustrating. Again I've lost 3050, characters. I give up. Very poor, not value for money. Avoid.

Absolutely amazing app. Definitely a competitor to ElevenLabs and others. They also give free credits to try everything out. Highly recommend.

What's wrong with this app? I have 977 credits and the cost of credit for the effect is 224 credit, and when I press transform voice, it says "Insufficient Credits"!!! Come on do you even know Math? You can tell me directly if you can't generate! You show that option to rate you 5 star so we can get additional (useful credit) You don't even deserve 5 star!
