Needs tweaking. *2026-07-10* This app is close to perfect. The weakest link by miles is the piano comping. It sounds really unnatural. Also, with the Swing rhythm I find myself wishing that the bass would just walk more. Lastly, export to wav would be a brilliant addition. ### 5/5 — Great for practice! *2026-06-27* This app stands out because of the realistic tracks you can create without a subscription. It even offers the ability to change rhythm and harmony along with transposition, tempo and key changes. I would like the app to transfer charts between devices, but it earns five stars as it is. Worthy of mention: I found a small glitch in using transposition and called it to the attention of the developer. I got an immediate response and the bug was quashed and in an updated version within days. Impressive! ### 1/5 — Now requires mandatory login *2026-05-05* Former standalone use is now prohibited. Bought this app without mandatory data sharing. This is made worse, as a previous e-mail exchange lead to doubts wether the author knows or cares, what data protection really means. Please add an opt-out to the login-screen! **Developer response:** Thanks for the feedback. This update introduced device sync and backup. It was one of the most requested features and is now available. We have been very clear about this change in the app description, onboarding flow, and app update notes. A few clarifications because parts of this review are inaccurate: • Email signup is required only for syncing and backup across your own devices. • No additional personal data is required beyond basic login information. • No user data is shared with third parties. We take privacy seriously. At this time, we are not planning to add a bypass for the login flow, since sync and backup are now part of the core app experience. ### 5/5 — Very Good *2026-04-20* Great sounding Sounds a lot better than iReal **Developer response:** Thanks for the feedback and the stars! 🙏 ### 5/5 — Does what it says on the tin… very, very well *2026-04-03* Your very own trio, covering most Jazz Standards and with the breadth of choice growing all the time. The App Store description is spot on, and it will run on Tahoe, too. The developer responds personally to clearly described bugs and, in my case, fixes them within days… wow! Find the standard you need, set your tempo, tweak the feel to your liking, and tweak the balance of the ensemble; all that within a few seconds. Then get on with learning the tune and practising your improvisation - the stuff you really need to be doing! Thank you Antonis, you’ve helped me make progress, big time! ### 1/5 — Mandatory Login? No Thanks *2026-03-21, version 11.9* Was good now I just deleted it, back to IReal Pro no login hassles required. ### 3/5 — Update broke some things *2026-01-28* Several songs won’t play audio since this update. I thought it was just when I searched for a song but I’ve discovered that there are just random songs that no longer work. **Developer response:** Thanks for the heads-up. That’s an easy fix on our side, we just need to know which song titles are affected. Please contact us at support@geniusjamtracks.com and include the song names. Once we have that, it literally takes a moment to sort out. ### 1/5 — Too many bugs *2026-01-22* I upgraded recently but I’ve experienced nothing but trouble since. It takes ages to load and when I do get to the song I want and press on it, it often sends me back to the main library. Very frustrating. **Developer response:** What you’re experiencing is not a bug. Please contact us at support@geniusjamtracks.com and we’ll guide you right away. ### 3/5 — Developer Says No Subscription Coming *2026-01-10* Correspondence from developer promises: NO SUBSCRIPTION coming after recent update. Seems shortsighted not to have include this in the updated App Store info. FYI, you can no longer access app until you give them your email and create an account. Update looks like a mostly polished GUI song browsing update, I’m not inherently seeing the reason for the necessary account creation. Will wait and see. **Developer response:** Thanks for updating the review, we genuinely appreciate it. Just to clarify a couple of points for anyone reading: the information you mention was already communicated in the app. On first launch after the update, there is a clearly visible “IMPORTANT UPDATE” notice explaining why account creation is now required. It’s understandable to skip past it quickly, but the information is there. The account wasn’t added for a UI refresh. It enables new functionality such as syncing your library across devices, sharing songs and playlists, and restoring your work if you change or lose a device. That’s the real value of it. For example, if your phone is lost or replaced, you simply log in again and all your songs and playlists are still there. We understand the hesitation, and it’s totally fair to wait and see. Now that you have the full picture, feel free to update the review if your experience reflects it. ### 1/5 — Bummer *2026-01-09* Like the old version better, don’t want to give y’all my email to use the app. Bummer, since I already paid for the app - oh well . **Developer response:** We understand the hesitation, but the account is required to support the new features. It’s not used for anything else, and we don’t collect or share personal data. There’s really no reason to worry about using your email. The account exists for your benefit, not ours. It enables syncing your library across devices, sharing songs and playlists, and restoring your work if you change or lose a device. For example, if your phone is lost or replaced, you simply log in again and all your songs and playlists are still there. Calling this a “bummer” doesn’t really reflect what we’re offering to our users or the value these features bring. Now that you have the full context, we’d appreciate it if you considered updating your review to reflect your actual experience with the app. If you’d like more information or have any concerns, feel free to contact us at support@geniusjamtracks.com. ## Frequently asked questions about Genius Jamtracks ### What is Genius Jamtracks?
