Every so often, we come across an app that makes us wonder “Why didn’t someone think of this before?” This is definitely the case with developer Dor Sakal‘s latest offering, FloatNote.

The app allows you to create a reminder note that will appear the next time you call a certain contact. It’s a simple concept, yes, but a very useful one nonetheless. Ever forget to invite someone over to dinner or compliment them on their new haircut? Then this app is for you.

Step 1: Install FloatNote

You can find Sakal’s app on the Google Play Store with a quick search of the term FloatNote, but if you’d rather skip straight to the install page, point your Android device to this link.

Step 2: Create a Reminder

When you first launch FloatNote, the app will give you a nice little overview of its features. Press the “What is it?” button to view the demo, then tap anywhere on the screen to head to the app’s main menu.

From here, simply tap the + button at the bottom of the screen, then select either “Choose from Contacts” or “Choose from Call Log”. Use the next screen to select a person for whom you’d like to create a reminder.

Next, just type in a note that you’d like to see when you call this person, then press the save icon at the top of the screen.

The free version of FloatNote limits you to 5 reminders comprised of 30 or fewer characters, but more reminders can be unlocked via an in-app purchase for as little as $1.77, and a unlimited version is available for $4.88.

Step 3: Use Your Reminder

Amazingly, that’s all there is to set up. You can forget about this reminder now, but you’ll see it the next time you call (or receive a call from) the person it’s associated with. A floating note will appear in your call screen interface when you contact this person, and you can move the reminder freely around the screen.

Like I said, this is one of those apps that just works on all levels. Has FloatNote helped you remember to broach a topic with one of your friends or family members?
