Serendipity Planner looks at your calendar, finds the gaps, and suggests a way to spend them. ■ Finds the gaps for you It reads your calendar and tells you where today has room. You don't have to go looking. ■ Picks by weather and place Outside when it's clear, indoors when it isn't. It points you to a café, a park or a bookshop near where you already are. ■ Set where you're headed Going somewhere today? Name the place, and suggestions come from around there instead. You arrive knowing what's nearby. ■ It learns as you go The app remembers what you pick and gradually leans toward what you like. ■ A widget for the next gap Your next free window, and an idea for it, on your home screen.
