I have tried deleting and re-downloading, restarting etc. but can’t get past registering pg. ### 1/5 — Can’t register *2022-01-01* This app doesn’t even let you register ? If it no longer exists it should be removed ### 1/5 — Useless *2021-12-13* Doesn’t work ### 1/5 — App doesn’t work *2021-07-26, version 1.3.0* When trying to make an account, I keep getting an error that’s says “The remote server returned an error (401) unauthorized”. Wireless! ### 1/5 — No longer supported/operational *2021-02-03* Website gone. Cannot log in / register. Nothing works! Very poor for HW costing thus much! It doesn’t take much effort to keep things ticking over! Never buying ResMed again! ### 1/5 — Stopped working!!! *2020-12-07* Was working so well and I loved it but updated to iOS 14.2 and it no longer works on my XS Please update!!!! ### 1/5 — Website certification revoked *2020-12-01, version 1.3.0* Web site revoked and splus wont work .. help! ### 1/5 — The new iPhone OS doesn’t work with ResMed *2020-11-25, version 1.3.0* On November 24 Apple updated their operating system which no longer works with Resmed. Ive used it for years and now it just crashes on opening. Oh well, it was great while it lasted. All good things come to an end eventually. ### 1/5 — Crashes *2020-11-23, version 1.3.0* I have been using this for years with no problems. But with iOS 14.2 it crashes on start up. Now it’s unusable. ### 1/5 — Doesn’t work with iOS 14.1 *2020-11-06, version 1.3.0* Crashes on launch! ### 1/5 — Don’t buy the expensive, worthless device *2020-03-24, version 1.3.0* Expensive machine is worthless. Emailed S+ before buying a new phone asking the requirements needed. They stated what they were, and I bought a more expensive device to meet the upgraded standards. Less than a month later I was trying to install the app on my new phone, and when logging in, I was getting error code 500. Apparently 3 months PRIOR to my initial contact with S+, they discontinued support, and the app, although you can still download both from the Google and Apple stores. Bad customer service! ### 1/5 — Needs an update *2019-12-16, version 1.3.0* This app is in desperate need of an update. Many features are broken such as the relax to sleep skips during playback and the back script that is written over on several screens. The app should be resized for the full screen phones out now. ### 1/5 — S+ It’s a rip off *2019-12-01, version 1.3.0* Don’t buy ### 1/5 — Won’t even load just crashes. Useless!! *2019-10-09* Failed ### 1/5 — App broken since iOS 13 *2019-10-04* Since upgrading to iOS 13 last night, I am now unable to sync the data between the app on my phone and the ResMed device. From the app, if I press the sync button the sync will attempt to begin then after a few second the app will crash. I have tried to disconnect and reconnect Bluetooth as per the instructions in the app. I have also tried closing all apps and doing a reset on the iPhone. This leaves me with a device that I am unable to use. ### 2/5 — Not let me sign up *2019-09-12, version 1.3.0* I try many time to sign up for the app and keep telling me several times that is an error and I can’t use it ... frustrated ### 2/5 — Hardware good, app terrible *2019-08-02* ResMed is a leader in CPAP and this hardware is excellent but the app is incredibly badly designed. It requires that your smartphone is near your bed (we usually keep it in another room while sleeping). The app must be manually started before sleeping and stopped upon awakening, and this is not a simple screen tap - you have to scroll down past questions it asks you to start it. If you hit the wrong part of the screen which is easy to do without glasses or when you are groggy then you have to navigate back to the main screen. It would be truly great if integrated with their CPAP and communicated directly with the website. It would also be better if the S++ device did not require cell phone proximity and if it detected sleep and automatically turned on and off. It would be extremely helpful to those of us with sleep problems if ResMed could improve the app. ### 1/5 — Stopped working and no customer support *2019-07-21* I used the S+ for almost 2 years then last week the app stopped working completely. Deleting and reinstalling App didn’t work, I can’t log in or even sign up as new account. They provide no customer help or contact information on the app. After I finally tracked down contact information on their corporate website the 800 number directs you to send email to an invalid customer service email address. Over $100 now completely worthless and very disappointing. ## Most critical reviews (10 lowest-rated) ### 1/5 — Can’t login. *2026-02-07, version 1.3.0* Can’t login anymore. I know the S+ system is discontinued but what are we supposed to do with the equipment? Throw it away? ### 1/5 — Can’t log in or create a account *2024-07-10, version 1.3.0* Found it in my sisters room and she told me I can keep it if I want to sadly the app for it won’t work PLEASE UPDATE ### 1/5 — ‼️I can't even login‼️ *2024-05-02, version 1.3.0* Unfortunately… I can not even login to the app 😩 Please… update the app‼️ ### 1/5 — Forget it *2024-04-26, version 1.3.0* App hasn't been updated in seven years and you can't log into the service anymore. Too bad because I dug out my old Resmed+ and was looking forward to giving it another shot. Why is useless stuff like this still in the App Store? ### 1/5 — Unusable *2024-02-25, version 1.3.0* Bought the device a few years ago, but the system now doesn’t let me log in, I can’t reset my password, and it won’t let me create a new account. If I go to the FAQs the site is down. It’s as if the app isn’t supported any more. It’s completely useless at this point. ### 1/5 — WtH *2024-01-24, version 1.3.0* No longer able to connect? No website says it’s not safe, no updates on app. No where to contact anyone. ### 1/5 — Now does not work at all *2023-07-29, version 1.3.0* Now does not work at all I thought by deleting and re-installing the app to fix some situation won’t even let me get into the app ### 1/5 — Can’t login! *2022-11-30, version 1.3.0* Useless app! Product still works but it won’t let me create a username and doesn’t recognize my old login! ### 1/5 — App won’t let me create a log in *2022-04-02, version 1.3.0* Every time I try to create a new user profile, the app says that an unknown error has occurred. I can’t get past the sign in/log in page. Kinda makes the entire unit unusable. ### 1/5 — Bad first Impression *2022-03-16, version 1.3.0* For starters, the app isn’t even letting me create a profile to even be able to connect my S+ Device.. I’ve tried multiple times, but every time I get the same “unknown error” message. It’s a real bummer… I had decent hopes for the device. ## Most praised reviews (10 highest-rated) ### 5/5 — Exceptional results thank you. My patient recovered. *2026-06-16, version 1.3.0* Exceptional results thank you. My patient recovered. ### 5/5 — TIP: Disable Wi-Fi on your phone to make app work *2019-04-25* Five stars for the support team who responded to my request right away. They also gave me a solution... Turn off WiFi on my phone... Setup account ... And it works!!! ### 5/5 — Solid app does what’s supposed to. *2017-11-19* It gives clear sleep data from the S+ machine. The doze off to sounds feature is very useful, it actually matches the rhythm of the users breathing to the selected track. Decent insights into sleep as well. There are a few flaws -can’t delete any sleep record despite it being your data. The graphs need more time points o n then. Naps need to be recognized as naps, and not included in sleep total graphs Waiting for the next update... Thanks Michael ### 4/5 — Self motivator *2018-07-02* As with anything purchased these days, it take a little work to reck the benefit of the device. Be true to the regiment and you’ll see and feel the benefits. Great product if used. ### 4/5 — ResMed S+ *2018-01-12* Been using for 3 weeks and although the improvements mentioned would be nice, it’s helped me. My biggest complaints are it cuts my iPhone alarm clock noise to low so now my clock is useless for charging iPhone. I’m trying to use my iPad with the app so my phone can still charge & alarm still work. Most desired improvement would be to have it combine multiple start and stop on the same day or allow a pause on tracking. Software could be much better but hardware is impressively correct. ### 4/5 — Easy to use, seems accurate *2017-12-23* The only thing I don’t understand is why the app penalizes me for sleeping eight hours. I understand that people my age (73) sleep about 6 1/2 hours on average. However, as far as I can tell the recommended amount of sleep for adults is still 7 to 9 hours. I have had scores of 97 and 99 for REM and deep sleep, yet my total score is 94 because I slept eight hours and 20 minutes. I generally average eight hours every night and I always have as an adult. ### 4/5 — Incompatible with iOS 10 *2016-10-22* Their workaround is to unpair the Bluetooth devices, reboot the phone and sleep monitor, then re-pair. Every night. The support email is useless - of my three emails, only one has been replied to, with the above. ### 3/5 — Log in problem *2021-08-18* I need to sync another device but the app will not recognise any of my email addresses. When I try and recover my password the message is address not registered . When I try and register the message is address already registered. I have a resumed S+ I can not use ### 3/5 — Decent but why can’t I use my speaker? *2017-12-31* I like to listen to music at night, or ‘sleep sounds’ like the ocean. Every time I start tracking my sleep, however, my music immediately stops playing through my Bluetooth speaker and my phone won’t even show the speaker as an option for use despite being connected to my phone. I don’t understand this and can not figure out how to fix it. I believe it’s something to do with the app but it’s frustrating because I can’t see a benefit for it. Other than that, the app works decently and the device reports my sleep data fairly accurately. If I could play my music (or the calming sounds offered in app) through my Bluetooth speaker I would do it in a heartbeat. ### 3/5 — Good hardware - terrible software *2017-10-29* Software is just buggy. Screens that won’t scroll to the bottom of text etc. crashes often and needs more detailed information of what these things really mean. Great hardware but software needs work. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
