Taskpile
Pick a shelf. Everything is sorted by how many hours it takes to finish at your pace.
Bring your lists into the app
The app on your home screen keeps its own lists, apart from Safari. Open taskpile.org in Safari, go to Settings → General → “Copy lists”, then come back here.
Use Taskpile like an app
Add it to your home screen: it opens full screen, works offline and is one tap away.
Drag a card by its handle to change the order.
