Shuodingle

Shuodingle is where you and up to three friends do one thing together. Agree on something you'll each do daily — push-ups, a journal entry, sleeping earlier, whatever — and light it up when you've done it. When a friend's light is on, you know they did it too. No streak grid, no day counts, no leaderboard. A few things, on purpose: · Just pick a nickname — no sign-up, no phone number · Make a pact with up to three friends, each lights up daily · Someone's been quiet? Nudge them gently, or keep a light on for them · A pact ends when it ends — you can leave it for the record, no forced renewal Shuodingle is deliberately small. No streaks, no rankings, no "keep going or lose your progress" pressure — just turning something you said you'd do together into something that actually happens.
