It is half-baked. I'm migrating the Android app to Compose Multiplatform to target Android + desktop, and eventually iOS. There is a mountain of work left to do!
If you used the installer from tasks.org/download you should find Tasks.org under 'Installed apps' in your system settings. Here you can click on ⋯ and select uninstall. If you have any more trouble with this please contact [email protected] to follow up with me!
Tasks exports json backup files, but editing these and importing them would not be convenient. You could synchronize with CalDAV or EteSync and look for a CLI client (e.g. https://calcurse.org)
One is the ability to schedule a repeating task based on the completion date rather than the due date. The other is to hide a task until a particular date
I use these two features together for all of my habits/chores that I don't need cluttering up my to-do list
You should be able to have all three installed at the same time
Open up your device's settings, click on apps, and make sure Tasks.org is not there. If it is, tap on it, tap on the overflow menu, and select 'Uninstall for all users'
The F-Droid version is built by the F-Droid build machine, not me, so it has a different signature. If you have the Google Play release installed then Android will only allow upgrades that are signed by me. If you uninstall the Google Play version then you should be able to install the F-Droid version
I use Apple Reminders on my desktop, but the Apple Reminders app is fairly basic and doesn't support things like subtasks or tags. And unfortunately the app abandoned the CalDAV protocol in iOS 13/macOS 10.15
Technically the Apple Reminders app can still be used with third party CalDAV servers, and third party clients can still synchronize with iCloud, but icloud.com, icloud.com list sharing, and Apple Reminders with your Apple account on iOS 13/macOS 10.15 now use a proprietary protocol.
Currently the Nextcloud Tasks (web) app offers the greatest feature parity with the app. Thunderbird + Lightning + TbSync is another option. There are some others but I haven't used very many. I've heard from a couple users that run tasks.org on their desktop with Bluestacks
The app supports infinite-depth subtasks, but there is no way to link two tasks at the same level
Subtasks are themselves tasks, so their priorities can be set separately from their parents. Collapsible subtasks will be displayed in searches and filters, so if you have a custom filter for high priority tasks, you will also see their lower-priority subtasks
Sharing is done at the list level, and this is handled by your synchronization service
I haven't personally used any command line CalDAV clients so I have nothing to offer there, sorry!
When you edit an existing task there is a big button on the app bar with a checkbox that completes the task. The button is not visible on a new task. Since you toggled on the "hide" option it will not be displayed at all.
If you toggle on 'Look and feel > Back button saves task' then you can use your back button instead of the save button up in the corner
Yes it does! The CalDAV URL is https://caldav.fastmail.com/. If you have 2FA enabled you will need to set up an app-specific password. E-mail [email protected] if you have trouble getting set up
Nextcloud supports list sharing, you can find some free providers at nextcloud.com/signup. EteSync also supports list sharing.
The app itself doesn't include any sharing functionality, but if you set up list sharing through your provider then the shared lists will appear on both user's devices
