DooNuts turns your todo list into a nut harvest. Every todo is a nut. When it's done, tap the nut: the squirrel carries it to the basket โ and your pile grows. PLAN SIMPLY โข Today shows what's due today, category by category. โข Later gathers everything with a date, week by week and month by month. โข As many categories as you like, each with its own nut: Work as a walnut, Home as a hazelnut, Sports as a pine nut โฆ โข Checklists: open a nut and tick off the small steps one by one. โข Hold a nut to move it โ into a new order or another category. โข Repeating nuts: daily, weekly, monthly โ they come back on their own. โข A calendar with every nut at a glance, per category too. โข Reminders at the time you choose, notes on every nut. โข Search across everything. HARVEST, DON'T JUST CHECK OFF โข Every finished nut lands in the basket. This season's harvest grows into a pile of nuts, next to the harvest of all time โ category by category. โข Every nut plays a note: each nut that lands in the basket and each tap on your pile plays the next note of the day's melody. โข Seven classical melodies, one for each day of the week โ played on a piano sampled note by note just for DooNuts. The note button switches melodies; the info button tells you what's playing. โข Tap the squirrel โ it's happy to see you. A SCENE THAT LIVES WITH THE DAY โข The view of the waterfall changes with the season, the time of day and the real weather: sun, clouds, wind, rain, thunderstorms โ plus snowy winters, sunsets and starry nights. โข The habitat: visit the squirrel and the deer by the river. CALM AND PRIVATE โข Everything stays on your iPhone. No account, no ads, no tracking. โข Your location is used for the weather only โ and only if you allow it. โข English, German and Japanese. DOONUTS PRO DooNuts Pro is all about the look and the sound: โข Three more critters: a flying squirrel, a ground squirrel and a dormouse. โข Three more instruments for the melody: pizzicato strings, vibraphone and synthesizer. โข Set the scenery yourself: any season, any time of day, any weather. โข Seven more app icons. Pro is a growing collection: new critters, instruments and icons join it over time.
