Bloomscrolling, but you have to go outside.
PocketPetal is a small game for walks. Snap any plant you pass and it joins your collection with a random rarity, Common to Mythic. Same odds for every plant, so a sidewalk weed can outrank a rose.
The names come from image recognition and are often wrong, so the match % is always on screen and you can fix it. It's a game, not a field guide.
