Wish the app would support padel ball settings. ### 5/5 — Very intuitive app for great product *2026-05-11* I’ve had the Proton for 6 months now and I’ve really enjoyed using the machine and the app. I’ve historically had a lot of trouble with groundstroke to approach shot transition, so the custom mode of the app really came into heavy use for me. It’s honestly delightful that the developers put so much thought into how a shot can be programmed. Totally recommend and I also think the Proton beats almost any other machine in the market at the moment. ### 3/5 — Badly needs a lock screen pause/play button *2026-03-16* The app seems functional enough but I see it as a safety issue for the user to have to take their phone out of their pocket and unlock it in order to pause the machine. A pause/play button on the lock screen, à la a music or podcast app, would be a major, major quality of life improvement for the overall system. ### 4/5 — Ball Machine itself is stellar when it works. *2026-03-13* The machine is fantastic when it’s working and the when the app is working—however, there is a good chunk of updates to the app that completely brick the machine or its programs on the app. Also the bluetooth receiver module on the machine itself seems so weak, I constantly have problems with the machine disconnecting from my phone mid hitting session. Aside from these issues the machine is great, the balls are heavy and really do make you a better ball striker. Also the customer support is great. **Developer response:** Thanks for letting us know — we’ve already pushed out a fix for the issue affecting oscillation in built‑in and custom programs. When you have a moment, please send a quick email to our support team (the address is listed on the Hydrogen Sports website) with your info so we can make sure everything on your account is taken care of. ### 1/5 — Latest updates broke almost all modes in the App. *2026-02-25* Any built in or custom program that uses oscillators no longer works. :( ### 2/5 — Frustrating App *2026-02-03* The machine itself is 5/5. The app is 1/5 and really drags the entire system down. Renaming custom programs is almost impossible. Sometimes they rename it works sometimes it doesn’t. Sometimes it seems like the renaming worked, and then you get out of the app and get back in and the renaming reverses to the old name. Super frustrating. The entire app needs to be redone to create a better user experience. **Developer response:** Hi there — thanks for taking the time to share this. Version 1.4.9 is quite old, and we’ve made a lot of improvements since then, including fixes for custom‑program naming, saving, and overall stability. We also have more updates in progress to keep improving the experience. If you can, send a quick email to our support team (listed on the Hydrogen Sports website) so we can take care of this directly and make sure your app is fully up to date. ### 5/5 — Latest update has problems *2025-11-16* Just download the latest update two days back and keeps hanging. Need to close the app and reopen and it does not let me make any adjustments in terms of speed etc. Just keeps hanging and need to restart . wish this can be taken care of ASAP. Update- the new update took care of the issue I had . I am able to edit etc.. thank you for the quick help. ### 3/5 — Latest update has problems *2025-11-09* Just download the latest update two days back and keeps hanging. Need to close the app and reopen and it does not let me make any adjustments in terms of speed etc. Just keeps hanging and need to restart . wish this can be taken care of ASAP. ### 3/5 — Machine great, app not *2025-09-29* App needs a UX designer. Custom programs are difficult to manage. Program name window is too short. Difficult to create a custom shot, customize it and test it. This is a great machine, but some care for the app would take it to the next level. **Developer response:** Hi there — thanks for the thoughtful feedback. Version 1.4.5 was one of our earliest releases, and we’ve made major improvements since then to custom‑program management, naming, editing, and overall usability. We’re also actively working on additional UI/UX updates to make creating and testing custom shots much smoother. If you’re open to it, send a quick email to our support team (listed on the Hydrogen Sports website). We’d love to make sure your app is fully updated and capture any specific pain points you’re still running into so we can feed them directly into the next round of improvements. ### 1/5 — New version doesnt work *2025-08-22* I installed the new version of the app. And now Im unable to create or modify custom programs. Ive been in contact with the support team. I keep getting told a reinstall is likely the quickest fix. Except, reinstalling the same, buggy version keeps resulting in the same outcome. Maybe the app development team will see this. I need the previous version of the app so I can use the custom programs. Otherwise Im limited to just using the control panel. **Developer response:** Thanks for calling this out — version 1.4.1 was an early build, and we’ve made significant fixes and improvements to custom‑program creation, editing, and saving since then. The issues you’re describing were real limitations in that version, and the newer releases address them directly. We’re continuing to refine the app, but you shouldn’t be stuck without working custom programs. If you can, send a quick email to our support team (listed on the Hydrogen Sports website) and we’ll make sure you get taken care of right away. ## Frequently asked questions about Hydrogen Sports ### What does the Hydrogen Sports app do?
