This is a simple app that should be easy to use and not require ads getting in the way. ### 5/5 — I like this app *2026-07-30, version 1.5* It is accurate and easy to use. ### 1/5 — Publicités insupportables *2026-06-29* Des publicités beaucoup trop longues ,insupportables et inadaptées **Developer response:** Merci beaucoup pour votre commentaire. Je suis désolé que les publicités vous aient autant dérangé. La toute nouvelle version 2.0 vient d’être publiée et apporte de nombreuses améliorations importantes : une interface entièrement modernisée, de nombreuses optimisations techniques en arrière-plan, de nouvelles fonctionnalités ainsi qu’une expérience d’utilisation globalement améliorée. La fréquence des publicités en plein écran a également été réduite afin qu’elles interrompent moins souvent l’utilisation de l’application. Si vous souhaitez utiliser l’application sans aucune publicité, la version Premium supprime toutes les publicités et plusieurs formules sont proposées, dont actuellement une option particulièrement avantageuse. J’espère que vous donnerez une nouvelle chance à la version 2.0. 🙂 Si vous trouvez cette nouvelle version plus agréable à utiliser, je vous serais également très reconnaissant de bien vouloir reconsidérer votre note. ### 1/5 — Klappt nicht u *2026-06-17* Bleibt seit einiger Zeit schon nach der Eingabe der zu berechnenden Daten in der Werbung hängen, die sich auch nicht mehr schließen lässt. App wurde gelöscht! **Developer response:** Vielen Dank für deine Rückmeldung, und es tut mir sehr leid, dass es bei dir zu diesem Problem mit der Werbung gekommen ist. Gerade wurde Version 2.0 veröffentlicht, die die App in allen Bereichen intensiv verbessert und modernisiert. Dazu gehören ein deutlich überarbeitetes und moderneres Design, technische Modernisierungen im Hintergrund, verschiedene Optimierungen sowie neue Funktionen. Auch die Darstellung und Häufigkeit der Werbung wurde verbessert. Ich würde mich sehr freuen, wenn du der neuen Version noch einmal eine Chance gibst und ausprobierst, ob das Problem damit behoben ist. 🙂 Falls die App jetzt wieder zuverlässig funktioniert und dir die neue Version besser gefällt, wäre es natürlich ebenfalls sehr schön, wenn du deine Sternebewertung noch einmal überdenken würdest. Vielen lieben Dank! ### 5/5 — Muito bom *2026-06-04* Adorei o aplicativo, muito bom para calcular datas futuras ao marcar algum compromisso. Pena que tem propaganda ao gerar resultado. Mas sendo gratuito, a gente espera. ### 1/5 — Нужно больше рекламы *2026-04-13* Реклама вылезает с каждым запросом. Есть куча других бесплатных и без рекламы приложений. Спасибо, удаляю. ### 1/5 — No fluidity *2025-11-01, version 1.5* Not easy to use and send you some sticky adds before you can get your calculation to be done. Add don’t want to disappear from your screen… but I do: I am about few seconds away from vanishing from their users list😀 ### 5/5 — Vá a pena. *2025-09-23* Esse app é excelente. Vale muito a pena. Gostei muito. ### 1/5 — Мошенники *2025-09-01* Оплатил за год подписки а через 2 месяца всё заблокировали. ЖУЛИКИ! ### 1/5 — Older version easier to use *2025-04-02, version 1.5* The older version was less key strokes ## Frequently asked questions about The Date Calculator PRO ### What does the Date Calculator PRO app do?
