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 – and your pile grows. PLAN SIMPLY • Today shows what's due today, category by category. • Later gathers everything with a date, week by week and month by month. • As many categories as you like, each with its own nut: Work as a walnut, Home as a hazelnut, Sports as a pine nut … • Checklists: open a nut and tick off the small steps one by one. • Hold a nut to move it – into a new order or another category. • Repeating nuts: daily, weekly, monthly – they come back on their own. • A calendar with every nut at a glance, per category too. • Reminders at the time you choose, notes on every nut. • Search across everything. HARVEST, DON'T JUST CHECK OFF • Every finished nut lands in the basket. This season's harvest grows into a pile of nuts, next to the harvest of all time – category by category. • Music if you like: with the melody on, each nut that lands in the basket and each tap on your pile plays the next note of the day's melody – or keep it to a simple plop. • Seven classical melodies, one for each day of the week – played on a piano sampled note by note just for DooNuts. The note button switches melodies; the info button tells you what's playing. • Tap the squirrel – it's happy to see you. A SCENE THAT LIVES WITH THE DAY • The view of the waterfall changes with the season, the time of day and the real weather: sun, clouds, wind, rain, thunderstorms – plus snowy winters, sunsets and starry nights. • The habitat: visit the squirrel and the deer by the river. MADE FOR IPHONE DUO • Open like a book: one screen becomes two. Your list on the left; on the right your week or your harvest, with your nut pile – one forest across both screens. Nibbit the squirrel carries your finished nuts across to the pile. • Half open like a laptop: the river comes alive above. Below, switch between your list and a music box: your nut pile becomes an instrument to tap, and after dark a soft night light. • Open and held upright: your list on top, your nut pile below. • Closed: everything fits the outer display. As you close it, Nibbit climbs down the side of your list; open it again and he climbs back to his seat. CALM AND PRIVATE • Everything stays on your iPhone. No account, no ads, no tracking. • Your location is used for the weather only – and only if you allow it. • English, German and Japanese. DOONUTS PRO DooNuts Pro is all about the look and the sound: • Three more critters: a flying squirrel, a ground squirrel and a dormouse. • Three more instruments for the melody: pizzicato strings, vibraphone and synthesizer. • Set the scenery yourself: any season, any time of day, any weather. • Seven more app icons. Pro is a growing collection: new critters, instruments and icons join it over time. DooNuts Pro is a monthly or yearly subscription – the yearly one with 7 days free for first-time subscribers – or a one-time purchase that's yours for good, no subscription. The app shows the price in your currency before you buy. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple account; manage or cancel it in your account settings. Everything that matters stays free – Pro takes nothing away.
