### 5/5 — Отлично!

*2026-08-17*

Программа из серии must have  для фото и не только. Удобно, информативно и полезно. Спасибо авторам!

### 5/5 — Mega App für Piloten

*2026-05-31, version 6.3*

Warum ich 5 Sterne vergebe? Weil es 6 nicht gibt!😁
Diese App ist ganz hervorragend. Der Entwickler ist selber Pilot und hat diese App  mit dafür angepasst. Für jeden Flugplatz kann man sich direkt Beginn und Ende der Bürgerlichen Dämmerung anzeigen lassen, für jeden Tag. Somit für Fluglehrer zum Erstellen von Flugdurchführungsplänen bzw. auch Flugaufträge mega. Damit ist man auf der sicheren Seite als Pilot.
Seit SERA ein muss für Piloten. Ich empfehle die jedem Schüler und auch meinen Fluglehrerschülern weiter.
Danke Vielmals an den Entwickler!

### 5/5 — Uhrzeit wird nicht richtig dargestellt

*2026-03-28, version 6.2.1*

In der Übersicht kann ich auf das Kalendersymbol klicken und den Tag und die Zeit auswählen. Rechts unten wird die Uhrzeit für die Auswahl nicht richtig dargestellt.

### 5/5 — Great info

*2026-03-26*

All may celestial dates and time in one place

### 5/5 — Beste App für Gebetszeiten

*2026-03-10, version 6.1*

Für Muslime um die nautische Morgendämmerung für den jeweiligen GPS Standort herauszufinden und dann den morgendlichen Fastenbeginn im Ramadan zu starten, besser und genauer, als islamische Gebetszeiten-Apps. Auch der Sonnenuntergang für den jeweilen GPS Standort, um das Fasten zu brechen, ist viel genauer als die Gebetszeiten-Apps. Ich nutze das schon lange und bin sehr zufrieden.

### 5/5 — Parfait et utile

*2026-02-14*

Utilisée chaque jour

### 5/5 — Calculo de la luz

*2026-01-11, version 6.1*

Muy interesante para calcular la iluminación solar en cualquier lugar y momento, para fotografia, viajes o excursiones. 
A mi me resuelve las necesidades al respecto

### 5/5 — A

*2026-01-01*

Clair et précis

### 5/5 — Alle Funktionen & Kostenlos

*2025-12-22, version 6.1*

Man kann sie Kostenlos benutzen und bietet alle wichtigen Funktionen. Sie ist nicht die hübscheste von der Benutzeroberfläche aber das ist egal. Alle anderen apps verlangen immer ein Abo wenn man die Zeit verändern will und das Datum.

### 5/5 — Einfach, schön, genau und hilfreich

*2025-11-09*

Ich hatte früher eine Armbanduhr, die Sonnenaufgänge und -Untergänge berechnen konnte. Und die Uhr war megaschwer zu bedienen. 

Welche Freude bereitet es da, bei jedem Gebrauch dieser App sofort die gewünschten Informationen zu erhalten. Und die App bietet sogar mehr Infos als ich benötige.
