This is a really good app, now I am able to get the amount of sleep I need with no guesswork on the matter and I feel much better for it, health has improved and so has my blood pressure, priceless.😀😀😀😀😀 I have had this app for a while now and I am still happy with how it works, but it can eat up storage space though it can be cleared.😀😀😀😀😀 Just to say there are lot of lovely sounds to wake up to, I recommend the Welsh Blackbird. Can’t think why I have not used this in a while but now I have come back to it. I like waking to the sound of birds singing, by far more gentle than a ordinary alarm clock.

Ce n’est pas vraiment un réveil. J’ai le sentiment que l’appli vous réveille lorsque que vous avez eu votre quota de sommeil. Ce n’est donc pas pour les gens qui bossent !

Update 27feb 2020: Developer got in touch with me after reading my first review. Explained that my iPhone had to be plugged into a charger for better reliability. Followed the instruction and the app has been working flawlessly. ——————- Nice app with good set of features, but on two occasions the alarm did not go off. Huge catalogue of sounds, including nature and rain fall sounds, that one can combine to create a personal alarm sound. Decent set of statistics is shown which is nice. Overall I would ask the Developers to focus on improving reliability. In its current state I see myself moving to some other app.

Mit der App ist das entspannte Aufwachen ein Kinderspiel. Fünf Sterne würde ich geben wenn man für jeden Wochentag individuelle Weckzeiten voreinstellen könnte. So muss der Wecker jeden Abend neu eingestellt werden. Dafür ein Stern Abzug
