Using now iOS 16.5 and aboslutely no sound comes off the app, when everything plugged like it used to be (with a classic iRig module). Very poor support on the website regarding any compatibility chart that would help figure out what the problem might be. Not sure what happened there… Sucks cause the app was nice to use! ### 5/5 — fun *2023-11-02, version 3.6.42* I prefer this app to tonex. ( not the pedal) Ive never tried the pedal. I find to be very intuitive, and easier to find a sound that works, in spite of its fewer options. with one output going through a reamp, into a really cheap amp and a 10" speaker, I'm more then completely satisfied, best money Ive spent towards guitar tone in a long long time.. ### 1/5 — Can’t record into cubaissis so i never use anymore *2023-08-25, version 3.6.42* Other than that it’s a great app just useless because I can’t record anything ### 1/5 — Please fix quick!! Unusable with iOS 16 *2023-02-08, version 3.6.42* Can no longer use the app in garage band! doesn’t open, now I can’t record my music! ### 1/5 — Only works with the built in iPhone mic, pretty useless with a guitar *2022-12-31, version 3.6.42* Oh well at least we have tone bridge ### 5/5 — iOS 16 issue *2022-12-26, version 3.6.42* I don’t why after updating to iOS 16, JamUp can’t connects with my guitar and interface anymore, plz fix the problem, thank you. ### 1/5 — Stop working *2022-12-21, version 3.6.42* It was great for our family Violin fun and training, but it just stopped working, and does not play anything more. I tried support, nothing… tried in-install and re-install, nothing… tried turn on and off the cell phone, and nothing. I have an IPhone13 and sadly it’s not working I hope in some point they will solve this issue Ahhh, the paid version, didn’t work too, so I asked for refund, and I’m waiting for it Please, make it work again Thanks ### 1/5 — Static *2022-10-16, version 3.6.42* Anyone know how to get the horrible static sound out of my headphones. ### 1/5 — Wow. Fooled again. *2022-03-30, version 3.6.42* So I’ve just downloaded this app, and was excited to use the metal amps, like the loomis or even the orange amp and come to find out they aren’t available. Wether you have to actually BUY them or you have to do something to access them is beyond me. I’ve been fooled again by these mobile amplifier apps, it’s all a money hungry system. Even the preloaded presets sounded terrible. I’ll stick to my amp sims on my MacBook that I’m not forced to pay to play. ### 3/5 — Killer tones but… *2022-01-24, version 3.6.42* JamUp won’t recall my saved presets rendering JamUp useless to me. I’m trying to replace MainStage on my Mac and I thought JamUp/iPad might be the answer. Bummer ## Frequently asked questions about JamUp ### What does JamUp do?
