I can connect Bluetooth for music but not the app. Even though this was part of the feature set ### 1/5 — English version does work!!! *2022-03-20, version 1.0* I can’t read Chinese! ### 1/5 — In Chinese language *2021-12-08, version 1.0* Not useful ### 1/5 — It’s all in Chinese *2021-06-16, version 1.0* It allows you to select english as your language, but then all the wording is still in Chinese. The app is unusable. ### 1/5 — Instructions are not in English *2021-01-09, version 1.0* Instructions are in Chinese!!! ### 1/5 — Chinese characters *2020-04-30, version 1.0* Same issue as the previous reviewer. Even though English was selected menu options shows up in Chinese whenever an option is selected. This app is not usable until this problem is fixed. ### 1/5 — English please *2020-01-08, version 1.0* App comes up in Chinese no language choice ### 1/5 — Pop-ups in Chinese *2019-12-27, version 1.0* Please fix this. The app is set in English, but for some weird reason everything that pops up is in Chinese instead of English. ### 1/5 — Great message chair terrible app *2019-09-12, version 1.0* All the error messages and sub screens are in Chinese even with English set as the main language . ## Most critical reviews (10 lowest-rated) ### 1/5 — used to work, but not anymore *2026-02-19, version 1.0.2* I really enjoyed the app when it worked but for the last year it has been a nightmare ### 1/5 — Goes dark *2025-02-21, version 1.0.2* Worked for a while, connect via Bluetooth does not work with any consistency. It wants to select device every time it started and goes unreadably dark on select screen. Cannot get app to connect via Bluetooth. ### 1/5 — Bluetooth Disconnect *2025-02-08, version 1.0.2* The app does not keep connection to Bluetooth. You opened, select your massage, and if you want to see time remaining or make a change you have to start all over again. From connecting to Bluetooth signal to everything else. ### 1/5 — Serious flaws *2024-12-21, version 1.0.2* It worked for a while. Now it continually thinks the chair is not turned on when you try to select anything on the menu. When connecting the phone, it does not filter the Bluetooth device list and shows every BT device it sees. When screen is in dark mode,the list of BT devices cannot be read. Once the screen sleeps BT will be disconnected, so to change settings after calibration you must reconnect BT. And it’s still a better UI than the built in controller. ### 1/5 — Select Device screen has black background *2024-07-04, version 1.0.2* Can’t see which Bluetooth device to select ### 1/5 — Bluetooth connection screen is black *2024-03-22* Can’t see which Bluetooth device to select ### 1/5 — Still NFG *2024-02-14, version 1.0.2* Why keep this app available if you don’t fix it? Language selection and power switch works. Every other button brings up a pop up saying the device is not turned on. ### 1/5 — Abandonware. Not updated in years. *2023-04-14, version 1.0* Language setting is ignored. All text is in Chinese. No longer connects to chair. They are still selling these new through costco but manufacturer has clearly abandoned the app. Other apps by the company seem similarly abandoned. Raises questions about product quality and support. ### 1/5 — Not working *2022-09-16, version 1.0* App not working. Keep asking to power up the chair. Please fix the app ### 1/5 — App stopped working with iOS 16 *2022-09-13, version 1.0* Please fix this. The chair is almost useless without the Bluetooth app. You’ll force many people to return their chair to Costco if you do not fix. This chair is too expensive to stop supporting less than a year after it’s been sold. ## Most praised reviews (4 highest-rated) ### 4/5 — 5 stars if you could save massage settings *2021-12-02, version 1.0* every time i have to go in and enable my manual massage settings. it would be so much better if there was an option to save a massage preset and enjoy the amazing massage the osaki gives. 5 star chair but app needs small improvements. ### 3/5 — Needs updated bad! *2022-03-09, version 1.0* This chair cost too much money to leave the app and firmware in this state. I want to love it but I just like it a little. Please tell me there’s an update coming or I’ll ship it back! ### 2/5 — Maestro Pro 4D from Costco *2023-12-30, version 1.0* Connect to the osaki Bluetooth with your phone and then connect with the app. It’s in Chinese until you are connected then the app seems to work fine. ### 2/5 — Need updates for IOS 16 *2022-09-17, version 1.0* Need updates bad, app does not work in current state. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
