todo.txt win is a todo.txt client for windows 10 devices. It works on mobile, tablets and normal computers and supports a part of todo.txt's protocol. While complete support is planned down the road, you can already use the app with your existing todo.txt files. It will not alter them in a way which makes them unsusable.
You can download it from the Windows App Store here: https://www.microsoft.com/en-gb/store/apps/todotxt-win/9nblggh678jj
Any bug reports/ideas/pull requests are welcome and will be considered :)
Thank you!
