So far the app has functioned excellently. I have not run into any issues. It's very simple and straight forward. However, I do recommend you read the user start guide as you'll find out about not so intuitive functions which make everything not only more seamless but even simpler than before. I would seriously recommend to anyone looking for a Todo app, I've been using the free version and no complaints and no ads. Definitely give it a try and you won't regret it.
