The only todo app that ever worked for me for several months was Habitica [1]. It&#x27;s the best gamified system I&#x27;ve ever seen, at the time it turned me in a big believer of gamification as the future of work. Until I basically reached a typical RPG plateau, and you couldn&#x27;t switch to a new character without losing all your progress forever, so I gave up. If only they had a mode where you could &quot;collect&quot; characters that you level up one after another, I would still be using it.<p>[1] <a href="https:&#x2F;&#x2F;habitica.com&#x2F;static&#x2F;front" rel="nofollow">https:&#x2F;&#x2F;habitica.com&#x2F;static&#x2F;front</a>
