Walkle is a daily word game. You get 2 guesses. That's it. Unless you walk, in which case you get more. This is the whole thing. Run out of guesses? Go touch grass, or better yet walk on it. More steps unlock another guess. Here is how it works: • You get 2 guesses free, always. • Walk 25%, 50%, 75%, 100% of your step baseline → unlock guesses 3, 4, 5, 6. • Your baseline adapts to your actual activity level over time. • Green = right letter, right place. Yellow = right letter, wrong place. Grey = wrong letter entirely. You get the idea. One word. Every day. Everyone's suffering together with the same word. After you finish, check your Stats to find out if you're more Brain (solved it early, minimal effort) or Brawn (walked 9,000 steps and got it on guess 6). Connects to Apple Health automatically. No account required. No ads. No visual clutter. Its baby's first app really (its me, I'm baby. This is my first app).
