I can not locate the Todoist App on Google Play (HTC) in order to download it to my phone.
in order to use our mobile site, simply go to https://todoist.com/m using your mobile browser (note - your browser must support HTML5).
We will soon release our brand new first-party apps for Android and iOS, but you can try out a variety of apps created by other programmers using our API. For more information, please go to http://todoist.com/mobile
I've been using Budoist on Android and it works pretty well.
