You keep forgetting things at the gym, the office or a friend’s place? Yoyo helps you remember what to bring for each occasion and asks again before you head home, so nothing gets left behind. GETTING READY Before you leave home, remember to complete tasks and confirm items as you pack them. Add what you are bringing from your Library, by typing, or from suggestions. WHILE AWAY At your destination, remember what to pick up or drop off, and confirm everything else is still with you before you head home. An item can be left somewhere to pick up later, dropped off where it was headed, or marked lost, and Yoyo goes on saying where it is until you tell it you have it again. BACK HOME As you unpack, put everything back where it belongs and finish the tasks that waited until you got back, so everything is ready the next time you go. THE PLACES YOU GO Save a checklist for each occasion and the places it stops at. Work day, gym, beach: each one is ready the next time you go, and something you need just once can be added for that occasion alone. Add your home too, and Yoyo can send a notification if you leave it while a checklist is still getting ready. FREE AND PRO Yoyo is free for five checklists, with no time limit. Yoyo Pro is one purchase for unlimited checklists. Private by design. No account, no tracking, no third-party ads. Your checklists, places and activity stay on your device, and back up to your own iCloud Drive if you switch that on.
