Remember turning over a rock just to see what was underneath? Flip Rock brings that little thrill to your pocket, one rock a day. Each day you get a single flip. Tap the rock, lift it, and see what you uncovered. It might be a beetle, a snail, a glowing firefly, an ancient fossil, or a plain pebble. Once in a while it's nothing but damp dirt. Whatever turns up goes into your field guide, and every entry teaches you something true about the real creature behind it. That's the whole game. No countdown timers, no streaks to keep alive, no pressure to come back. Just one small, calm moment of curiosity a day, and a collection that fills in over weeks and months.
