It really works, thank you. ### 5/5 — Best App Ever! *2024-08-08* I tried a bunch of different gamepad tester apps, they're full of ads, can't test the select and option buttons, can't test the vibration motors. they're all bad. This app is 100% the best one! I would definitely pay for this app 👍🏽 Very well done, all features work. Great to see the stick positions as number values too. Thank you for releasing this :) ### 1/5 — What! *2024-07-29* Keep getting kicked out. ### 5/5 — Aide vraiment pour régler joysticks ps4/ps5 *2024-04-05* Vraiment efficace pour savoir le drift sur les joysticks ps4/ps5 . Grace à cette appli , je vois si les joysticks sont bien centrés Il suffit de brancher uniquement la batterie sur la carte mère de la manette démontée après avoir connecté la manette en Bluetooth avant démontage à iPhone . Comme ça sa évite de tout remonter pour démonter si ça ne va pas . Car pour trouver les bons réglages ça peut devenir une belle galère. ### 5/5 — Лучшее приложение для проверки геймпада *2024-02-05* в приложении нет рекламы и ненужных кнопок, все бесплатно, проверяет разные вибрации, заряд, нажатие кнопок, положение пальцев на трекпаде и тд. и все бесплатно ### 5/5 — Marche super bien *2023-03-11* L’appli est cool et simple , l’un des seuls gamepad tester qui marche, je l’est utiliser pour mon joystick gauche de ps4 et sincère nickel rien à dire, interface simple, une petite pub tout en bas mais qui gêne en rien, super 5/5 🙂 ## Frequently asked questions about GPchecker ### What does GPchecker do?
