Too many things to do? Which one first? Which Thing First? (WTF?) helps you decide. Instead of staring at a long list, it shows you just two things at a time and asks the one question that cuts through: which thing first? Make a few quick, easy choices and WTF turns them into a clear, ranked order - so you always know what to do next. Love a method like Getting Things Done (GTD) by David Allen? Even with a great system, one question remains: which thing to get done first? That's the gap WTF fills. It's a refreshingly simple way to prioritize. No due dates to juggle, no system to learn. Just compare, two at a time, and let the ranking fall out - and watch a beautiful animation bring your prioritized list to life. Everything you need, nothing you don't: • Multiple lists - keep separate ones for work, home, what to read next, anything • Share a list - export it as text, copy it, or send its items to Apple Reminders • Siri & Shortcuts - ask for your top thing without opening the app • Available in English, French, Italian, German and Spanish • A fast, clean, fully accessible design for modern iPhone and iPad Perfect for: • To-do lists and tasks you can't seem to start • Deciding what to read, watch, play, or buy next • Ranking options when every choice feels equal • Anything that needs a clear first, second, third Free to use, with a one-time upgrade (no subscription) to unlock unlimited lists and items. No ads. No accounts. No tracking - your lists stay on your device. Made with care by a small, independent studio. Thank you for trying it - and if it helps you, a review means the world.
