Comments on Simple Calendar for Android

★★★★★ Amit Patil · Jun 13, 2026

Simple UI and easy to use. That's what I want in any calendar

★★★★★ Charles Abiodun · May 23, 2026

Very simple and easy to use. Intuitive. The only grouse I have with it is that it is VERY slow in loading which is sometimes annoying and detracts from its beautiful performance and user-friendliness. I still give it 5 stars all the same because it's actually good except for this slow-loading problem. I pray the developers work on this.

★☆☆☆☆ T&T · Jun 13, 2026

Can you please stop responding? I'm leaving a review of your app. Yes your free version has ads, yes buying premium doesn't have ads but adds more clutter, I get it. That means this is not a simple calendar which is what the app is called. If it was simple then there wouldn't be bothersome ads on every open, and there wouldn't be a premium to add more cluttered features. Hence why a one star, this is not a simple calendar. If it was simple it would be just a calendar with no ads

Trust & Safety: Open-source, offline-first operation supports privacy and security. The app requests calendar read/write, notification, and networking permissions, among others, and provides a long description of privacy-focused, offline use. Review of requested permissions is advised; the app’s offline mode can reduce online exposure while offering CalDAV syncing for broader calendar compatibility.
