Microsoft has bought Wunderlist and merged it to Microsoft To Do app.
After testing multiple todo list I dare to announce Wunderlist as the simplest one with just right amount of features. You can categorize tasks to folders and set reminders if needed. Additionally it’s possible to attach files or notes for each task. That’s all I need from a task list.
At some point I tried Google Tasks-to-do-list with and idea to integrate it more closly to Google’s office tools such as calendar. In reality I never use task list for anything else than to write the task down and mark it as done. That’s why I switched back to Wunderlist.
The mobile application exists for both Android and iOS and works seamlessly via browser too.
