Going to abandon this. Not that useful. ### 5/5 — Funktioniert *2024-04-06* Die App macht, was ich soll und sieht gut aus ### 4/5 — Keine Daten *2024-03-30* Zum Start dieser App hat alles reibungslos funktioniert und hat auch Daten angezeigt, die mir geholfen haben. Mittlerweile zeigt die App jedoch nur an, dass nicht genügend Daten vorhanden seien, um einen Wert zu berechnen. Ich trage meine Apple Watch (S9) jede Nacht und habe auch alle Daten in Health. Somit ist die App leider funktionslos :/ ### 3/5 — Good Looking & Simple to Understand *2024-01-24* A little to basic depending on your needs or wants. Works well simple attractive layout. Need some more features ### 3/5 — Fehlende Daten *2024-01-05* Leider bekomme ich kann Zahlen zur Körpererholung und zum Sauerstoff! Ich nutze die App in Verbindung mit einem IPhone 15 Pro und einer Apple Watch Series 9 und Ultra 9. Sonst finde ich die App schön und übersichtlich gestaltet. VG Thomas ### 4/5 — Schöne App *2024-01-01* Hab mir die App heute geholt , gefällt mir sehr gut Nach kurzer synchronisieren zeigt die alle Werte an. Die Widget sind nicht ins deutsche übersetzt. ### 1/5 — Nur Anzeige AppleHealth Daten *2023-11-26* und das machen andere besser wie zb gentler streak. Der selbst ausgedachte Score ist unwissenschaftlich und mit dem kurzen Verlaufszeitraum völlig nutzlos. App wieder gelöscht. **Developer response:** Danke für das Feedback. Der Score wird aus Körpertemperatur, Herzfrequenz in der Nacht sowie der Atemfrequenz berechnet. Je höher der grafische Wert, desto erholsamer war die Nacht. Es gibt keine Y-Achse, keine maximalen und keine minimalen Werte und keine Einheit, da der Wert für jeden Menschen individuell ist. Anhand des Scores lassen sich jedoch Abweichungen von der baseline ablesen, was bedeutet, dass die Erholung geringer ausgefallen ist. ### 2/5 — Hübsch aber nutzlos *2023-10-29* Die App ist sehr schön aufgebaut und designed. Das größte problem ist aber, dass die App nicht die „Sleep Recovery“ anzeigt. Nach Monate Benutzung (Handy auf Schlaf Fokus stellen, Autosleep tracking) zeigt die App immer noch an: „More Sleep Data required“. Wenn diese problem behoben werden würde, würde ich auch 5 Sterne geben. Abgesehen davon, zeigt die App aber Heart Rate, Resting Heart Rate und Noise an. (Ich benutze noch die Series 5). **Developer response:** Bitte einmal schauen ob alle Health-Berechtigungen gesetzt wurden. Manchmal zeigt Apple nicht direkt alle zum Start an. ### 3/5 — Pretty bare bones *2023-10-26* I just paid for this app, which is pretty rare based on a review that I saw, rarely a good idea. While I like the concept, the data presented is impossible to evaluate. The key metric, body recovery, is only a line graph with no numbers, and no way to evaluate what it means. Worse, there is no history, only seven data points which I infer to mean seven days. So what am I supposed to do with this? Also, the App Store description says the app provides recommendations based on your recovery score. If so, I surely can't find them. This app requires much more development before it's useful. ### 5/5 — Super App *2023-10-23* Meiner Meinung nach die schönste App auf dem iPhone - übersichtlich, und ein super ansprechendes Design! **Developer response:** Vielen vielen Dank! ## Frequently asked questions about Sleevi ### What devices are required for SleepRecovery?
