Die Brille funktioniert sehr gut, hilft einen gut in den Tag zu starten und einen guten Schlaf zu bekommen :) Das einzige was etwas unnötig ist, ist das man sich für die App registrieren muss was überhaupt keinen Sinn macht und eigentlich nicht für die Funktionen der App relevant wäre. ### 2/5 — Почему приложение вылетает? *2021-09-14* Установила, зарегилась, но при вхоже вылетает. ### 1/5 — Crashes *2021-09-10* The app simply crashes after signing up 💁‍♂️ ### 1/5 — Doesn’t retain data entered or give instructions *2020-02-19, version 2.8.2* The app doesn’t give much in the way of instructions and seems like it should be intuitive. I got my glasses paired, filled out the questionnaire and got signed in. When I tried to update the “Me” section it doesn’t save any data entered. The date displayed is Tuesday 1/15 when today is Wednesday 2/19 and it indicates for sleep tracking but again no real instructions. I’m not sure if I’m supposed to open it before I go to sleep and again when I wake up but getting it to connect with other apps that do track this (sleep app, health app, etc) would be more efficient. This has the potential to be really great and the device itself is doing a lot for my sleep but advertising an app for it that doesn’t do anything seems like poor marketing judgement. ### 1/5 — Won’t pair with my phone *2020-01-16, version 2.8.2* Doesn’t matter what I tried. Can’t pair with my phone. ### 1/5 — Can’t sign up *2019-08-15, version 2.7.4* I’m trying to sign up. I keep getting an error message that says, “Fail to sign up” but doesn’t say why. I tried a few different passwords with different lengths and characters. I also tried different user names and once got an error that said it was too long. ### 5/5 — Pegasi *2019-06-14* Супер очки ! Стал спать как младенец , начали сниться сны 🌈 перестал вставать по ночам 🤓 ### 1/5 — Broken *2019-01-06, version 2.6.4* “Network Anomaly” displayed repeatedly; cannot login, cannot reset password, cannot create new account. My $210 glasses are now useless. ### 5/5 — App works now *2018-11-20* App works now so disregard the above review. App has everything plus in it and I just started with it today. ### 1/5 — No longer stuck in Chinese but cannot make an account. Get your act together! *2018-11-04, version 2.5.9* No longer stuck in Chinese but now you cannot make an account. When going through the set up process, you enter your email address and are supposed to receive a message with a verification code to continue making the account. Never received even after attempting multiple times and checking spam folder. ## Frequently asked questions about PEGASI Sleep ### What does PEGASI Sleep do?
