### 1/5 — Trop de pub

*2025-03-23, version 10.7.1*

Pratique il y a quelques années, maintenant c'est une pub toute les 10 secondes, inutilisable et supprimé

### 4/5 — Avis

*2024-10-04, version 10.7.1*

Le calendrier républicain devrait, à mon avis, s’ouvrir sur l’an I car c’est surtout pour la révolution de 89 que ce calendrier est utilisé et remonter tout es années est fastidieux .
Sur iPhone la barre de défilement des jours est partiellement cachée par des couleurs trop vives.
Belle application

### 3/5 — Même pb, un souci dans le calendrier chinois… 2022 égal annee du tigre ! application me demande

*2024-09-30, version 10.7.1*

Malgré l’achat de l’application, sa réinstallation… À chaque fois elle me demande mon avis… Je suis très content de l’application sauf avec ce bug qui me fâche vraiment ! Vivement une modification, s’il vous plaît !

### 4/5 — Suggestion

*2024-04-12, version 10.7.1*

Nice app, but do you mind reducing the frequency of fullscreen video advertisements while introducing banner advertisements as replacements?

### 4/5 — Mon choix

*2022-03-19, version 10.4*

Dommage que les calendriers choisis en bas d’écran ne sont pas stables et à chaque ouverture nous retrouvons votre sélection

### 1/5 — Keeps asking for feedback every 2 seconds

*2022-02-21, version 10.4*

Like I it says

### 5/5 — Communication svp :)

*2021-12-10, version 10.2*

Bonjour Jacques, j'adore ton application et je l'utilise beaucoup. La mise à jour d'il y a quelques semaines a cependant modifiée considérablement le visuel pour les jours du calendrier Républicain. Je l'aimais mieux avant, pour plein de raisons !
J'aimerais communiquer avec toi, pourrions-nous nous contacter ? Merci !!

### 1/5 — Dégradation catastrophique

*2021-11-29, version 10.2*

Pub tous les 3 calculs, injonction à donner mon avis à chaque calcul, ça rend l’appli totalement inutilisable si je veux chercher une date. Que se passe-t’il ? Ce n’était pas comme ça avant. Et toujours pas de prise en charge de Split View sur iOS. J’avais cette appli depuis plusieurs années, je vais en chercher une autre pour remplacer. Dommage

### 5/5 — Love learning about the French days of the week!

*2020-08-13, version 5.7*

Love learning about the French days of the week!

### 3/5 — Modifier l'ordre des icônes

*2019-09-04, version 5.7*

Comment mettre le calendrier hégirien à la place du calendrier maya, par exemple ? Les icônes ne veulent pas bouger dans l'onglet "modifier".
