Why a Place Comes Back

Each place you study has its own schedule. The app brings it back around the time you'd be likely to start forgetting it.

Find It, and It Waits Longer

Find a place and it waits longer each time: days, then weeks, then months. Miss it, and it comes back sooner.

Your Tap Does the Grading

Tap inside the outline and it's correct. A quick tap counts for more. Tap a neighbor, or just outside, and it's close. Anywhere else on land is a miss. A tap on open water isn't an answer; the card waits. There's nothing to rate afterwards.

Today Shows What's Due

Some days that's a lot, some days a little. A few minutes a day is the whole idea. Cramming isn't needed, and it doesn't earn you anything extra.

A Few New Places a Day

They arrive chapter by chapter, or from the whole deck at random. You choose, and how many a day is up to you in Settings.

The Globe Shows the Schedule

• Uncharted · You haven't met it yet.
• Sighted · You've encountered it at least once.
• Charted · Holding for weeks.
• Mastered · Comes back rarely.
• Fading · Due for review, or missed recently.

Mastered means you'll probably remember a place for at least a month, so it won't come back for a while.

Mastery comes from the schedule itself. There's nothing to set.

Missing a Day Is Fine

Nothing is lost. The places that came due are marked Fading and wait for you. Your first session back runs longer, since everything that came due is waiting. The streak starts over, but the schedule doesn't.

When Today's Study Is Done

You can keep going, if you want to. “Learn More” gives you another batch of new places, and “Study Ahead” asks about known places before they're due (which earns a little less progress than waiting for them to come due would have). Reviewing your mistakes at the end of a session is practice, and doesn't change the place's progress or your overall schedule.

That's all of it. A few minutes a day goes a long way.
