I study 10-30 minutes a day once (have a lot of cards in a lot of topic) and I just don't miss a day no matter what. I use the Anki mobile app if I can't use the computer on a day. I'm very lazy, but even I find this method very easy to do. I just made it as a habit; wake up, do the Anki review quickly and that's all.

Also I prefer a desktop app, because it's open all day, and whenever I encounter a new info, I immediately put it into Anki!
