Background updates are turned on in settings for the app on my iPhone 17 and my iPads but if you leave the app open on other devices you have to go to settings in the app and and hit sync to up day each device. If you don’t complete a dated task it doesn’t automatically move it to the next day. Which I think it should do then maybe change the color to indicate it was brought forward from a previous day. The widget on iOS is basically worthless because of the topics mentioned above and you don’t get to choose which checklist appears there. Maybe I want to see my work checklist widget on my work devices and my home checklist widget on my personal devices. ### 5/5 — Remembering Tasks *2026-06-26* As I age, it is good to have a reliable tool to keep up with appointments and tasks. One Tasks is the app for the job . ### 3/5 — Good App *2026-01-02* Easy to use but I am failing to locate a link to assign tasks to my team ### 5/5 — Nice for Organizing *2025-11-13* I like how the tasks directly transfer into the calendar app, making everything organized and flow smoothly ### 4/5 — Good app *2025-11-06* Good, easy to use app. I love that it syncs across devices. I like the features and how user friendly it is. A no fuss to do list, which is exactly what I needed. My only requests would be to have the ability to color code each task. Also manually sorting or being able to star/prioritize a task within a list would be helpful too. ### 5/5 — The BEST! *2025-10-24* One tasks and one calendar are simply the best calendars out there. They’re free and integrate with other calendars. I’ve used them for years and I’m so happy with them. ### 5/5 — Good app *2025-10-16* Good, easy to use app. I love that it syncs across devices.
