Among the reasons are that it’s easy to use, looks great, is affordable and the support is fantastic — fast, friendly and accurate. ### 5/5 — Solid Calendar is solid! *2025-06-30, version 2.75* Finally! A simple calendar app that works. It offers different views, it’s easy to add entries, and once I got my Mac and iPhone calendars in sync correctly, it works great. (My problem; not the app’s!) I am delighted and strongly recommend this app if you like simple software that just does its job. Well done! What would I add? Just an option to display little checkmarks for appointments that I’ve finished. No need to cross things out or change the order of display. Just a little checkmark or dot to visually mark things as done. ### 5/5 — So close to perfection that stress melts *2025-06-30, version 2.74* I love using this app and bought their productivity bundle because my life is inextricably, organized and tied in ways I never realized. From calendars to habits to productivity, focus tools, EVO and the other bundle have been exceptional. When set of feedback guy would offer is a better task management landing pad, so that Dail to-dos do not have to be tied to reminders or calendars. Floating to-do’s on my widget page would be rad too. Just a passing thought ### 5/5 — Great App *2025-02-24, version 2.70* Lovely design, simple interface and solid performer. ### 4/5 — Solid Calendar Review *2025-02-10, version 2.70* Just downloaded the app along with its companion apps. Great working concept: not bloated; straight-forward; ease of use and visually appealing. ### 5/5 — Zippy, fast, gorgeous *2025-02-01, version 2.70* This app is great. It loads quick, it’s easy on the eyes, and it does a great job of fast natural language interpretation. I’ve tried almost every calendar app out there, and this one is the best value by a long shot for my needs. Highly recommended! ### 5/5 — A phenomenal calendar app! *2024-11-20, version 2.66* Background: I’ve tried a lot of calendar apps, my main one was the default apple calendar prior to this one because sometimes the simplest is best. However, I wasn’t a huge fan of the mobile appearance of apple’s calendar app. A while back I bought the solid apps bundle to try, and didn’t really try to integrate them into my life. Finally got around to it, and solid calendar is incredible! It provides a sleek design that isn’t overwhelming or requires a subscription. I also appreciate that the calendars and reminders are simply the ones on my device, so it’s still relatively secure. I know many are not fans about the requirement of an account, but it to me it is not the end of the world and simply a requirement for multi-device sync. Definitely give this app a try! ### 5/5 — A solid calendar app indeed. *2024-11-09* I just needed a clean and minimal calendar app with natural language processing and this exactly does that. ## Frequently asked questions about Solid Calendar ### What does Solid Calendar do?
