Does today's walk count? StepDay tells you. You walked today — commuting, errands, the dog, a stroll after dinner. But did any of it count as exercise? StepDay answers just that: whether it counts, how far short you are, and how to close the gap. No watch required. The Daily Verdict One glance, one answer: • "It counts" — today's brisk minutes met your goal • "Moved" — you moved, a few brisk minutes short • "Crushed it" — you went past your goal • "No signal" — your phone probably wasn't with you, and we say so We acknowledge what you did before telling you what's missing. No red rings, no "you failed". Share today's verdict as an image in one tap. Japanese Walking, Guided A few minutes short? One tap starts Japanese walking — 3 min fast + 3 min slow × 5 — with a Live Activity countdown and pace guidance on your Lock Screen and Dynamic Island. Finish, and today's verdict updates. No Watch Needed Reads Apple Health and your iPhone's own motion sensors — an Apple Watch is not required. No custom step engine, no competing with the system's numbers. StepDay Pro • 30-day brisk-minutes trend • Weekly review: which days counted, and why • Personal baseline: goals that adapt to you, not someone else's 10,000 steps • Custom interval pacing Privacy First Everything stays on your iPhone. No account, no uploads, no location tracking. The free version always shows today's verdict and gap. Pro includes a 7-day free trial.

Verdict
The clearest difference is ads: StepDay at none against Plankstar's shown. StepDay also leads on update cadence (fortnightly vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
