Not sure who thought that was a good idea. Controller customization works as it should when the menus are accessible and readable. It’s be great if some updates were made to improve the UI and usability. ### 4/5 — Pretty good *2026-01-26* Overall great app but has a few flaws with macros. Only allows increases/decreases of 5ms and only goes down to 20ms. Also seems to mess up my macro time to time when I press it. ### 2/5 — can i play efootball?? *2024-12-01, version 3.77* 3 ### 4/5 — 我对这个软件的建议 *2024-10-07, version 3.76* 建议添加这两个选项： 1.在USB连接电脑时默认使用Switch协议； 2.在XInput协议连接下使用任天堂按键布局。 还有就是制作一个更简洁的图形界面。 ### 1/5 — X10 *2024-05-15, version 3.75* Won’t connect to app ### 1/5 — Connectivity *2024-05-04, version 3.65* Joy cons won’t connect after first use ### 1/5 — Turbo won’t turn off *2024-03-27* if you purchased this item. return it. it’s cheap and developers didn’t do well on the app. the settings won’t let me turn off turbo, only thing i can do is change the lighting. money wasted. please don’t buy this. ### 4/5 — Impressed *2024-03-25* Connecting was easy came up right away. Map keys very easily except a few that were not listed, but this was all given in directions it came with to do so manually without app or anything, app makes it simple incase u forget how.. Lots of features for a app like this.. impressed Again change up where it can read all buttons/back buttons and it’s lit. ### 1/5 — Controller app *2024-03-02* It needs an update because I have a controller that needs this app and when I click on turbo, it just kicks me out needs a big update please update this app asap ### 1/5 — 一坨屎 *2024-01-29* 一点都不好用，有些功能也不能用 ### 1/5 — The worst waste of money *2024-01-25* The only thing the app does for my controller witch I only had for a day, is connect it to my phone and nothing else. If I press any button available in it, it will not do anything. The only thing it does is connect, and disconnect my controller. Can’t even use it ### 1/5 — bad experience by *2023-10-09, version 3.60* I just got mine in mail today. was super excited to use it and it didnt work. Looked it up on youtube and found the app. downloaded app. used app and it just finds it and throws a error when i try to update controller. maybe mine is just a part of bad quality control. It’s basically an expensive battery that only last 8 hours tops ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless *2026-04-11* It detected my dishwasher but not my controller that was on ### 1/5 — Don’t install it *2025-11-05* The app works for the controller but the main issues is you start getting those mcafee virus scan pop ups once you install it ### 1/5 — GREAT ! *2025-07-31* This would be a great thing to have if only it were for keyboard and mouse. Roblox is hard to play with only touch screen and I only have keyboard and mouse. But Roblox is not keyboard and mouse supported .. only controller supported. As I can not afford a game controller. ### 1/5 — It can’t find my controller *2025-06-16* I keep refreshing it and I still didn’t see it i tried on my actual Bluetooth it showed up HATE THIS APP please delete it or fix the app 👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎 ### 1/5 — No PS5 *2025-03-11* Not seeing PS5 controller either in search mode or connected ### 1/5 — Can’t get past bluetooth *2025-03-09* I am using a switch pro controller and it is not showing up. ### 1/5 — Buttons *2024-09-24* Could be my mistake but also tutorial could be a bit better. I was using it to play COD mobile I would press “Y or X” whatever it is for you, it would quit the game as if I swiped up from bottom to top and I went into the app to try and change it but I don’t think it’s possible and if so how? And could we make the app easier to use? ### 1/5 — I can’t find my controller *2024-06-08* 👎 ### 1/5 — Doesn’t work with xbox controller *2024-06-03, version 3.75* It appears, but as soon as I press on it it’s gone ### 1/5 — Joy cons *2024-05-25, version 3.75* (Same user different id) joy cons won’t continuously connect when needed ## Most praised reviews (10 highest-rated) ### 5/5 — Hyperion 3 *2026-06-25* Works as it should, downloaded and updated my Hyperion 3 for the Nintendo switch 2. ### 5/5 — Worked perfect for Hyperion 3 *2026-04-25* I installed and updated my Hyperion 3 Switch 2 joycons in less than a minute. Worked perfect. ### 5/5 — Hyperion 3 Switch 2 *2026-04-01* App works great with no hiccups for the Hyperion 3! ### 5/5 — Worked on NYXI Hyperion 3 *2026-03-25* I downloaded this app for the new NYXI switch 2 controllers to connect and update firmware with my switch 2 and surprisingly it worked so I was pleased ### 5/5 — Best app ever *2026-01-26, version 3.81* The app updated my nixi nj12 controllers and mapped them really well ### 5/5 — No stick calibration *2025-04-07* It’s the best app ever and works on my iPhone 6 but one issue I have stuck drift and the app has one single feature missing,no stick calibration! Please fix this I was playing fortnite when I started spinning in circles due to the controller thinking a was pulling it to the left! Please add a calibration for the sticks! Other than that great app ### 5/5 — Works 😤 *2024-12-21* crying cause you didn’t implement my improvements 😫 ### 5/5 — Works with ELISWEEN Switch Pro Controller *2023-11-05* Very easily detects, connects, and updates multiple Elisween Switch Pro controllers. Haven’t tried programming buttons but I haven’t needed to. ### 5/5 — E *2023-04-08, version 3.34* I take it back it all works you just need to make sure your controller is on the wright device setting on the back of the controller all the features work and you can fully Customise mode your pro controller to how ever you want. overall it is pretty good ### 5/5 — Everything works as expected and then some *2023-01-19, version 3.34* This app works great with my Etchpower wireless controller for the Nintendo Switch. I had no trouble connecting to my controller. I love how customizable this app is. I especially like how you can adjust the lights on the controller from the app. I also love that I can customize inactivity auto-shut down timer and even set to infinite (never turns off unless you manually do it). Note for those of you who just bought this controller I recommend checking the auto-shutdown setting (located in the “other” header) before you attempt to customize the controller on this app. Also to get the rainbow color or the actively changing between 9 colors with breathe feature you have to set manually it through the controller buttons. To change the lighting on controller press and hold the turbo button and double click the left or right analog stick (L3 or R3) to switch between modes and flashing rainbow color. Hold turbo and single click left or right stick to change colors. I wish the app had these light features available. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
