Just the standard stuff: Calendar - I have a CalDav server running which provides CardDav as well but there are plenty of commercial alternatives. In addition I use the notes app - without sync - on my phone to plan days if there is a need for it at that day. Like many others here, I also tried this todo-$timeframe approach. It's better than nothing. But honestly, since I have my own Redmine installation pursuing any long term goal or complex personal project becomes actually doable and isn't a pain anymore. (Trello etc. would probably work as well but I like that it's open source and provides a lot of interoperability which I didn't set up though yet) What I especially like is the Gantt chart feature and that tasks can be split (manually of course), set in dependency and to some degree stuff automatically gets rearranged when it comes to the time frame. My only recurring daily todo is somehow to actually use these tools.
