About

How was today? elou asks one question and keeps your answer as a single colored square. Over time the squares become a year you can read at a glance. ONE TAP A DAY Pick Good, Okay or Bad. That's it. If you want to say a little more, add a short note about what made the day feel that way. YOUR YEAR, IN COLOR Every day you log fills in a square on your year ribbon: sage for good, sand for okay, terracotta for bad. Swipe back to see earlier years, and see how many days you've logged in each one. LOOK BACK, GENTLY Tap any day to read what you wrote. Your most recent entries sit under Lately, so the last few days are always close by. MISSED A DAY? Tap its empty square and fill it in. You can edit any entry later, too. EVERY MOOD COUNTS The colors are earthy on purpose. A bad day isn't an error, and logging one counts as much as logging a good one. PRIVATE BY DESIGN Your entries stay on your iPhone. There's no account to create, nothing to sign in to, and no ads, analytics or tracking. elou never connects to the internet, so your notes are never sent anywhere.
