### 3/5 — Sur la bonne voie

*2026-08-22, version 3.5.3*

Application avec du potentiel à un prix abordable. Reste du travail à faire pour le rendre plus intuitif et avec la possibilité de changer la vue de nos événements et rappels. Il faudrait améliorer la gestion des calendriers: je n’y comprends rien! Avoir des références facilement accessibles nous aiderait assurément.

### 5/5 — Leider ohne Monatsansicht

*2026-08-17*

Die App ist gut gemacht, die Bedienung gibt keine Rätsel auf. Leider ist die normale  Monatsansicht im Querformat nicht mehr vorhanden, die wie im Hochformat in einer Ansicht alle Termine darstellen konnte. Diese Übersicht gab es m.E.n früher bei der alten App. UPDATE: Die Monatsansicht zeigt nen auch im Querformat alle Termine, danke.  
Der Preis für den Einmalkauf fürs iPhone finde ich angemessen, Abos für Software mag ich generell nicht, in so fern ist es gut, daß es Einmalkäufe gibt.

**Developer response:** Die Monatsansicht im Querformat ist weiterhin vorhanden. Bei Fragen dazu bitte melden: support@calendar366.com

### 1/5 — Adding/editing/duplicating broken

*2026-08-15, version 3.5.2*

Adding/editing/duplicating events is aggravatingly broken. Seems every time I create to add or duplicate an event, Calendar randomly adds Alerts I did not ask for and I can NOT delete those. Seems every time you duplicate something, it adds Alerts anew. This is SO BROKEN that I can't even figure out what skewed logic it's using. Even when created anew, event will have extra Alerts I DIDN'T want or ad myself. I seriously would not have upgraded if I knew it is so BADLY BROKEN! And, most importantly, this all happens although I have made sure there are NO default Alerts in Settings. FTW?!

### 4/5 — Weiterhin der produktivste Kalender für mich

*2026-08-13*

Die Ansicht „Monat und Liste“ ist immer noch mein Hauptargument für diese App. Apple ist etwas nachgezogen, aber man kann die Liste nicht durchblättern und der Kalendertag ändert sich. Die Kalendergruppeb sind ebenfalls top und so kann ich verschiedene Widgets gestalten und nutzen. Bei der Mac-Version wünsche ich mir, dass man den Zoom bei der Stundeneinteilung einstellen kann. Ansonsten habe ich das Geld gerne ausgegeben!

**Developer response:** Danke! Bei Fragen oder Anregungen gerne melden: support@calendar366.com

### 5/5 — Love the re-designed Aesthetic and Functionality

*2026-08-02, version 3.5.1*

I think I have had your application since the start and I enjoy the pleasure to use it every time due to the following main characteristics:
Design
Features
Aesthetics
Functionality
Ese of Use
Thank you for creating this application and for the continuous updating to keep it current to new software versions. 😃

### 5/5 — Mir gefällt die Neue …

*2026-07-24*

Ich hab mir die Neue Version angesehen und fand sie auf dem ersten Blick gut. Es ist anders als die Alte aber nach einigem Probieren finde ich es auch noch Übersichtlicher, besonders auf dem iPhone und bei den Aufgaben. Ich hab daher gerade die Pro Version für iOS gekauft. Mir gefällt die Neue und so wie ich es bei der Alten erlebt habe wird auch die Neue Version bestimmt noch besser.

### 4/5 — Good, but could have been better for old users of 366

*2026-07-22, version 3.5*

I finally purchased this app and it’s a definite upgrade. Calendar 366 ll was really nice, but this one has more features. I do kind of miss the dark color theme of that one though. This app is extremely useful but it should have had an upgrade path for old users. Like I haven’t bought the Mac app yet bc I already bought it for the previous version of the app, and I don’t want to pay $30 extra for that. That’s kind of a bit extreme. I do like the new widgets and features enough to get my value out of this, but I don’t necessarily think you should go all out on supporting this app with your wallet on all platforms anymore just bc you don’t know when a new release might come out. The lifetime purchase on iPhone watch and iPad though I think is worth it. Just not on Mac. 

If I didn’t come from the previous version this would be a 5/5 easy. But I’ve been using this calendar 366 app platform since like 2023 or 2022 I think. So I have something to compare it to. I don’t like other calendar apps not from this developer nearly as much. This is just too useful for how it syncs between platforms and how it works for putting in events and reminders for me not to recommend.

### 1/5 — Not an upgrade bait and switch!

*2026-07-21, version 3.5*

This is not an upgrade but full bait and switch. If you paid for the other version but deleted it thinking it was an upgrade, your loss. Looks like I’m looking for another app now.

### 2/5 — Mike

*2026-07-15, version 3.4.1*

Old one is better

### 4/5 — Tolle Ansichten 📅

*2026-07-12*

Update:
Heute (So. 12. Juli), nach dem Urlaub, habe ich mal die Lifetime für Familien gekauft. 
Bis jetzt kamen ja einige Updates raus und ich hoffe es wird noch weiter verbessert. 
➡️BITTE noch ein alternatives „kalendermäßiges“ App Icon😎✌️

Hier sind schon einige die den Preis kritisieren. 
Und im ersten Moment war ich auch auf der Schiene. 🤷🏻‍♂️

Aber mal nachdenken:
Lifetime für ewig und jede neue  Version?
Heult nicht rum wegen den paar Kröten damals: unglaubliche 8 Stück?🙄

Dann habe ich mal 
 1 Tag später drüber nachgedacht, mir die Preise für Lifetime nochmal angeguckt und muss sagen: die Preise sind absolut fair. 
Vor allem die für Familie (6 Personen!)
- es gibt da 2 Versionen:
a) iPhone, iPad & Apple Watch
b) iPhone, iPad & Apple Watch + Mac
Super👍

Hier kann man sich wirklich nicht beschweren. Auch die anderen Einmalkauf  Preise. 

Zur App: die ist neu und gerade erst gestartet. 
Wenn die  App einige Updates und auch etwas feintuning (bei Widgets: z.B. Rotes S/Zahlen für Sonn-/Feiertage, blaues S für Sa. Und die Zahlen darunter passend einfärben!) für die Oberfläche bekommen hat, wird sie sehr gut sein. 

- Das + Zeichen sollte man kleiner machen. Es sollte die gleiche Höhe haben wie die Bedienelemente links. Das würde viel besser  aussehen:) 

Die Agenda Ansicht ist richtig cool❗️🤩

Auf dem Mac gefällt sie mir auch sehr gut. (Dort habe ich auch eine Bewertung geschrieben). 
Sie erinnert mich an Fantastical mit den ganzen Ansichten. Mir gefällt sie👍

Ps: das App Symbol könnte man aber etwas überarbeiten. 
Mehr Kalendermäßig machen😅 Es erinnert mich mit dem aktuellen „C“ extrem an Carbon Copy Cloner. 🤓
Ich hätte das App Symbol lieber in einer anderen Farbe bzw. Farbkombi. 
Da sollte man vielleicht 5-6 Varianten zur Auswahl anbieten. 😉
