The interface is clumsy but easily navigated. ### 1/5 — Horrible!!! *2025-04-04, version 4.4.8* App crashes OFTEN! Sometimes a few times, in the same day! Only way around it is to delete the app, and then reinstall. ### 1/5 — Nope. Connectivity Issues *2024-12-05* Pay $4,500 for a chair with an app that offers many more options than chair remote, and IF you connect, then chances are 0.00% that it will connect next time. Pure disgust. For this reason I’d not recommend this company’s products. ### 2/5 — Needs updated! *2024-01-21, version 4.4.8* These chairs cost a good bit and the app for them that adds functionality should be updated. The back arrow is up in the corner where it is hard to make it work since it is basically under the time display. ### 1/5 — Terrible app that detracts from the chair *2023-11-23, version 4.4.8* iPhone 11, the buttons at the top and bottom are very hard to activate. The saved settings change randomly. That is, when I use a saved setting and adjust the chair sometimes it saves those settings and sometimes not. This app is clearly abandoned. When it comes time to buy a new chair I will purchase something else. ### 1/5 — Gravis app👎 *2023-06-27, version 4.4.8* Our gravis chairs are great. The app - not so much. I can’t choose my chair. I choose both serial numbers in bluetooth settings but only 1 chair works. It appears the app is 3 years old. Isn’t it time for an update. The chairs are very expensive so the app should be as good as the chairs. ### 1/5 — Why is this app 2 yrs old????? *2023-04-22, version 4.4.8* Just got second Gravis delivered and now can no longer select the first chair. Not even an option. What gives. UPDATE the app please. Hire and outside company if you have to. This can’t be that heavy of a lift. You are a big company with expensive well made products and you let an app like this exist? Big miss Human Touch ### 1/5 — Version Hx Tells It All *2022-11-07, version 4.4.8* This app hasn’t been updated in two years. Ridiculous, since if you have more than a single chair you are required to memorize a 7 digit number to know which one is yours. Comfortable chair but remote operation only for the owner who knows exactly which one is his. Would be easy to allow renaming feature to more easily identify. Would not buy another. Follow-up to the above. It seems that there is simply no effort to up the game on this chain and the app. DO NOT BUY THIS CHAIR! Overpriced and oversold. Manufacturer clearly doesn’t care about the sale…maybe discontinued. I would rate -3 stars for the app, 4 stars four chair comfort, 1 star for operational design (total mismatch on embedded button design…hold the rear button to go forward and the front button to go backward. Handheld does not light up in the dark, on/off button is not intuitive. Designer obviously never used the controls of the chair. However, the motor works well. ### 5/5 — LOVE THIS APP AND CHAIR *2022-01-01, version 4.4.8* App was very easy to understand. Like all the extra features it allows you like heat setting temp. Fantastic chair. Time for a nap and a massage now. ## Frequently asked questions about Gravis Chair ### What chairs does the Gravis Chair app work with?
