It works perfectly

Ok, it’s not free but you can try it for free. Once you try it you can decide if it’s worth the money to you. I am still deciding that for myself having just installed the app. What I can say however is that it works extremely well and you aren’t getting a cheap product so if this is an app that interests you I highly recommend downloading the app to try out the free trial because you won’t be disappointed with the quality. This is light years better than any free options out there like audacity and it’s presets lol.

Good but……

I love this game but first of all everything I have to pay for. It is so annoying I just wanna listen to some songs and plus this song is in Spanish and I don’t know how to speak Spanish. I speak English. I just want a few things to change. I want everything to be free like every song and some songs to not be free because it is so annoying you know how you have to pay for everything and it is so annoying. I don’t know why the fact we have to pay I just wanna listen to drivers license crying in my prom dress just dance dance monkey diamonds in the sky and more the only thing can you change is that can you just make sure that everything doesn’t cost money

Developer Response ,


Thank you for your feedback and for using Stemz. We understand your concerns about the cost associated with some songs. Our app operates on a freemium model, which means we offer a free version with some limitations, and a subscription version that removes these limitations and allows unlimited track imports.

The reason we charge for some songs is to support the artists who create them and to cover the costs of maintaining and improving the app. However, we're always working on ways to provide more value to our users, and your feedback is valuable in this process.

Regarding the language issue, we're sorry for any inconvenience. We're working on adding more songs in different languages, including English.

We appreciate your patience and understanding. If you have any other suggestions or concerns, please feel free to share them with us.

Best regards,

I put five stars so this is at the top. The AI itself works great but then it hides EVERYTHING behind a paywall or a premium membership. I was testing it and it let me play about 5 seconds of a 12 second video before it said “well you can’t listen to anymore cause I’m greedy for cash🥺 but you can get premium for $10 a month or pay $2 for a 12 second clip”. It’s a free app for all this just make it a paid app rather than baiting people in with a free app just to make them pay to do anything
