Questellar turns building habits into a game. Make your tasks into quests, and earn Stardust each time you finish one. Every day you live lights up as a star in your night sky, and that star grows on its own as much as you build up. [ How it works ] - Create daily and weekly quests and complete them. - Recurring quests come back each cycle; goal quests fill progress toward a target. - Attach today's tasks under a bigger goal so everything connects in one line. - Break a big quest into a checklist to work through it. - Keep your list tidy with favorites and archive. [ Your growing star ] Your star grows with the Stardust you gather, and when your rank rises you awaken it yourself to evolve the star. From an ember to a star, a supernova, a galaxy, and beyond to transcendence. Tap the star for a reaction worthy of your current rank. [ Records ] On the Records tab, the days you live light up as stars. The more you do in a day, the brighter it shines. Look back on your days at a glance. [ The promise ] Stardust can only be earned by real completion. It can't be bought, and nothing here sells an advantage. Your star is built only from the days you have lived. No account, no login. Everything is stored safely on your device. Korean and English supported.

Verdict
The clearest difference is ads: Questellar at none against 리턴's shown. Questellar also leads on iOS requirement (16.4 vs 18.0). On price, update cadence, in-app purchases and device support there is nothing between them.
