I think the app could be a little clean such as in the search bar it should give you suggestion by relevance. And categories so that I can choose whether I want hip hop,country, or etc. But other than that I love the app. Please continue adding songs. And maybe add something like we get to choose any one song for free, when we first start using jammer. add accounts so we can save our mixs. Or add an option to make a ringtone. Thank you for this app! I love it!

This app is literally my dream app and is the most amazing idea; I love everything about it. After playing around with a few songs I noticed they were only “previews,” and I realized you couldn’t go back to the song you tried out unless you payed for it. I saw that it was $0.99 for unlimited playtime. I considered purchasing until I found out that it’s $0.99 per song. If it was $0.99 and we could unlock all premium songs for unlimited playtime, I think you’d have way more business. Or even if you didn’t charge, tons of more people would get your app and you guys would still make money. If you absolutely MUST charge us, do it reasonably and responsibly. Make it $0.99 or $1.99 to unlock ALL the songs unlimitedly. Otherwise there’s no point to this app and it’ll die out soon. Thanks for reading and I really appreciate if you would consider this, as many people would agree with me.

The app itself is good, makes the good remixes but there are many issues I came across in the first few minutes. Firstly, nothing is free. You get a 30 second trial of the song but then you must pay for it to use the song again, there are NO free songs and I don’t want to pay for every song. The next issue is there is no Kpop, I know it is not an issue with popularity because my favorite group BTS is topping the charts and I am a very big fan of it and so I wanted to try and make something off some of my favorite songs but they are not there, really upsetting I expected more music choices.

I’m obsessed with this app. I just downloaded it and I can’t get enough! However, I don’t agree with charging .99 per song. I’m willing to pay, but I’d rather pay to play all songs for unlimited time instead of paying to play 1 song. I saw your response to another user, and that’s great that the money goes back to the artist, but I truly think you would make more money AND have more users if you gave the option of paying for unlimited use on all songs.

I really enjoyed this app and I was fully engaged in it, but I just don’t see myself spending money on it. I don’t see the app keeping my attention for more than a week at most and there aren’t a lot of songs to choose from. It would be really cool to build a community where you could possibly share the remixes you make with other users, or if users could create mashups, and most definitely a greater music selection.
