### 1/5 — Prefer Actual Numerals on Clock Face

*2026-08-10, version 1.7.2*

dissipated displayI’d love to see actual numbers (numerals) on the clock face. 🙂

### 5/5 — Proper Clock

*2026-07-01, version 1.7.2*

Very clear and I use to set up my watches

### 5/5 — Ole Miss Rebels

*2026-06-21, version 1.7.1*

I have never kept a clock or watch that doesnt keep near perfect time.

### 5/5 — Pro‘s und Contra‘s

*2026-06-18*

Ich möchte auf dem Bildschirm gern eine klare, irnfache, runde Uhr.
Die Zeitanzeige einfach nur auf dem Tisch in einem ansprechenden Format hilft deine verfügbare Zeit effizient und bestmöglichst zu nutzen.
Wichtig für mich: einfache Darstellung sowohl in Analog Anzeige, die mittels ihrer Kreisform den Fortschritt der Zeit besonders plakativ darstellt, als auch die digitale Anzeige, die sehr unauffällig mitläuft und an der ein zeitlich gesetztes Limit einfach abzulesen ist.

+tolles, weil schlichtes Design
+einfacher Wechsel zwischen Analog und Digital

-eine WERBEFREISCHALTUNG, die bezahlt wurde, kann nicht von einem user auf 2 Geräten verwendet werden. Habe auf dem Pad bezhalt, auf dem Handy habe ich noch Werbung!
Ich hielte es für fair, wenn die Werbung Nutzerspezifisch freigeschaltet würde.
