But it hasn’t been updated in 5 years at the time of this review. It could definitely use some polish to work better with the contemporary OS. ### 3/5 — Everyman *2023-12-05, version 3.1* Your Everyman schedules are completely wrong. Basic Everyman I is 11 PM (23:00) to 5 AM, with 1 nap from 1 PM (13:00) to 1:20 PM (13:20). Everyman II is 11 PM to 3:30 AM, 8 - 8:20 AM, and 2:30 - 2:50 PM. More info can be found on polyphasic.net. ### 3/5 — Almost perfect *2023-05-10* No easy way to turn off alarm entirely that I’ve found ### 4/5 — Hi *2023-02-05, version 3.1* First thanks for making this app. It’s going to definitely help with my polyphasic sleep cycle. What I would like to say is that I think if you got this to sync with apple’s health app… I think it could go a long way with helping those of us who have a different t sleep cycle. Thanks. ### 4/5 — Good but needs some features *2021-08-22* Shall have a way of saving multiple presets copying defaults or other preset customizations. Sound volume missing. But above all, a watch app is badly needed to make it complete. ### 3/5 — Da migliorare *2020-12-27* Sarebbe bello avere un tracciamento del sonno, la possibilità di inserire un piano di adaptation è una sveglia che funzioni decentemente ### 4/5 — Alarm will not work with Do Not Disturb *2020-12-15, version 3.1* Nice for setting schedule. Alarm doesn’t seem to work when Do Not Disturb is enabled, which is a bit of a problem when doing segmented sleep. Could do with a Watch app/complication. ### 4/5 — Zeitumstellung :/ *2020-10-25* Seit heute die Sommer- auf Winterzeit gewechselt ist, hat die App ein kleines Darstellungsproblem. Mir kommt es so vor, dass sie mit der Zeitumstellung nicht zurecht kommt. Wäre super, wenn ihr euch das mal anschaut. Ansonsten gefällt mir die App richtig gut. Simpel aufgebaut und individuell anpassbar. :) ### 5/5 — Would like a few features *2020-06-30* This is a great app. I’d like to see the option for notifications for 5 min before your sleep time starts and compatibility with itunes tones for notification sound (not sure if third party apps can do that one though). Also maybe a rate your sleep screen after your nap is done. Using it for everyman 3, and it is a very simplistic and logical app! Great help for keeping track! ### 2/5 — Alarm ausschalten nicht möglich *2020-06-02* Und wie schalte ich den Wecker wieder aus? Die Funktion fehlt einfach mal. **Developer response:** Hallo, Sie können entweder den Ton im Einstellungsbildschirm der App ausschalten oder die Benachrichtigungen für die App im Einstellungsbildschirm des Telefons deaktivieren. ### 5/5 — Use it every day! *2020-05-18* Simple and clean design, thank you! ### 5/5 — Great *2020-05-03, version 3.1* Missing alarm ## Most critical reviews (10 lowest-rated) ### 1/5 — Not worth the premium *2023-09-03, version 3.1* Better set up manual alarms. Its UI QUALITY IS INADIQUATE ### 1/5 — Paywall junk *2023-04-15* Worthless ### 1/5 — Some idiot mistakes need fixing ( paid app ) *2021-11-12* Ok I really like this app but you need a 1 star for attention to this review to become five star. #1 You did not give us a way to TURN OFF THE APP / ALARM. Unacceptable and pure idiot! Come on! What are you thinking? This is the 1 star reason mistake because its such a silly and obvious mistake… #2 Custom alarms instead of force us to use only your sounds. Also obvious mistake but dont care much about it. #3 Alarms / More notifications settings which go off with X specified amount of time before alarm ( for notifications when to get ready for core or nap ) Fix #1 and I change my review. #2 and #3 not so important for changing this review. ### 1/5 — Bug - premium does not work *2021-07-12* I bought the premium features for 3,49€ but still I cannot use the premium that I already paid for, because it still asks me every 10 seconds if I want to buy the premium features. What is that?? ### 1/5 — Spam nach Installation u. Funktionen ohne Mehrwert *2021-05-08* Habe eine brandneue Mobilfunk-Nummer und diese mit noch niemanden geteilt. Wenige Stunden nach Installation habe ich die ersten Spam SMS erhalten. :( Da diese die einzige App ist, die ich auf meinem neuen iPhone je installiert habe bei der unter "App privacy" nicht angegeben war worauf die app zugreift, ("details not provided") gehe ich stark davon aus, dass diese App der Auslöser für den SMS Spam ist, indem sie auf meinen einzigen Kontakt (meine Nummer) zugegriffen hat. Extrem ärgerlich und unnötige Zeitverschwendung. Und BTW die Seite napchart punktcom ist WEITAUS besser in jeder Hinsicht UND kostenfrei! Nur ohne Wecker, aber wer es mit polyphasischem Schlaf ernst meint, wird von der lächerlich simplen Weckfunktion dieser App während der zombie mode Übergangsphase eh nicht richtig wach. Fazit: Diese App ist die reinste Enttäuschung. ### 1/5 — Zu billig, zu teuer *2021-01-31* In der kostenfreien Version gibt es keine brauchbaren Funktionen, 3.5€ die das, was die App eigentlich können sollte scheint viel zu viel. Wäre die App technisch aufwendiger, wäre dieser Preis sicherlich gerechtfertigt, jedoch wird hier nur versucht sich an einem Nischen-Markt zu bereichern. Einfacher ist es, in der Kalender App seiner Wahl einen extra Kalender für seinen Schlaf-Plan zu erstellen, und diesen evtl. mit Apps wie Widgetsmith (kostenfrei) Home Screen Widget present zu halten. Das bietet mehr sinnvolle Funktionen, iCloud-Synchronisation über alle Geräte, mehr Komfort und ist kostenfrei. ### 1/5 — Not enough confidence to purchase *2020-06-19* The free version contains only one biphasic sleep schedule (nobody needs an app to add one 20 min nap to their day), and so little can be customized that I’m not willing to buy the full version. I have very specific needs and a 5-8 sleep phase schedule in mind, and I don’t feel certain the full version will work for me. Sorry. ### 1/5 — Missing key features *2020-05-19* App is missing critical features even in the premium version **Developer response:** Hello, Please send me more info about features that you are missing to support@alexeykuzovkov.com ### 1/5 — Что за ерунда? *2019-11-17* Купил полную версию. Через время снес, сегодня решил востановить прогу, и снова сняли деньги ? Что происходит и с чего вдруг я снова заплатил? ### 1/5 — Daylight savings... *2019-11-04, version 2.3* It didn’t adjust to daylight savings and you can’t manually change the time. ## Most praised reviews (10 highest-rated) ### 5/5 — BEST APP FOR POLISLEEPERS. *2024-02-27* Best app by far. ### 5/5 — Parfait *2024-01-24* Simple, efficace, il y a tout ce qu’il faut, c’est jolie et ça marche parfaitement, ne changez rien l’appli est parfaite ### 5/5 — I love this app! *2023-10-03* Great app, great UI. Next time I get paid I'm buyin the subscription. ### 5/5 — 12 Hour time and some more features *2023-02-17, version 3.1* Great job on the app. Please update, at least keep it compatible with the latest stuff just in case some future OS update could break the app. ### 5/5 — If you don’t know what it does: *2022-12-14* This app reminds you to sleep and plays alarms at set intervals at the same times to keep you in check for polyphasic sleep. The alarms are beautiful and better than default apple ones. I wish there was an app description or a guide when you open the app because I did not know what this was before using it ### 5/5 — Systematically fluid *2022-08-21* In all aspects of what a polyphasic sleep schedule enlists; this app is properly developed & executed in the sense that it allows one to further the crevices of time in the layout of how the circadian rhythm is being adjusted throughout the experience. Enjoy to anyone undergoing! ### 5/5 — So simple, I think its perfect. *2021-10-06* The UI and design is very minimal, choose your schedule and times, and put down your phone! I use this for my Biphasic sleep schedule which allows me to use it for free, even if you sleep monophasic. Paid version allows more options. I cant think of much to add or change, I dont use apple watch or need anything fancy. Highly recommend! ### 5/5 — Great! *2021-04-23* The app is great. I am not able to take advantage of staying up longer and not be tired all day. I wish they could tie their data with the Apple Health Platform. ### 5/5 — Sehr zu empfehlen *2020-09-23* Ich wollte schön länger mit Polyphasischen Schlaf anfangen, aber mir war das zu viel da den Überblick zu halten. Diese App ist super schick gemacht, sehr übersichtlich und hat alles was man braucht um seinen Schlaf im Überblick zu halten. Dieser Appkauf hat sich gelohnt 👍 sehr zu empfehlen ### 5/5 — Great app *2020-08-13* Great app- saves you years of your life. Just the transition period will be though --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
