About

QuesToDo

Features
Read full description

QuesToDo turns your daily to-dos into quests in a small RPG. Finish a task and you earn XP. Your adventurer levels up, learns skills, and unlocks new pixel-art gear. Nothing about the task list changes — what changes is that clearing it visibly moves something forward. Most to-do apps are hard to stick with because completing an item does nothing. In QuesToDo, every completion shows up as growth. ◆ Quests - Three difficulties (Easy / Normal / Hard) that award different XP - Repeats: daily, chosen weekdays, every other week, or every N days - Due dates with optional times, priorities, and genres - Folders, search, sorting, and drag-and-drop reordering - Tapped the wrong one? Undo the completion and carry on ◆ Growing your adventurer - Earn XP on completion and assign stat points on level-up - Over 50 skills: spells, techniques, titles, and passives - Activate a skill once a day to boost the XP you earn that day - Achievement titles that unlock from how you actually use the app ◆ Pixel-art avatar - Over 80 parts across hair, clothes, accessories, weapons, and shields - New parts unlock as you level up — dress your adventurer your way - Completion animations play the effect of the spell or technique you triggered ◆ Built to keep you going - Streak tracking for consecutive days - Daily reminders, due-date alerts, and a heads-up when a streak is about to break - Share your level-ups to X ◆ Records (Premium) - Total XP, monthly and yearly completions, and a range of averages - Charts by month, by weekday, and by time of day, so you can see your own patterns ◆ Premium (In-App Purchase) - Removes banner ads - Unlocks Records (statistics) - Plans: Monthly (auto-renewing, 1 month) / Yearly (auto-renewing, 1 year) / Lifetime (one-time purchase, yours forever) - Prices are shown on the plan screen in the app and in the In-App Purchases section of this page ◆ About auto-renewing subscriptions - Payment is charged to your Apple Account at confirmation of purchase - The subscription renews automatically at the same price for the same period unless auto-renew is turned off at least 24 hours before the end of the current period - Your account is charged for renewal within 24 hours prior to the end of the current period - You can manage or cancel auto-renewal any time in your App Store account settings All of your data is stored on your device, and no account or sign-up is required. Backups can be exported and imported. Register your first quest and start the adventure.
