Most days end without an answer to a simple question: did any of that actually move me? Mark is an intention journal built on evidence — a quiet record of what you did, and an honest read on whether it counted. Most tools optimise the plan: tasks, projects, schedules. Mark optimises the evidence. HOW IT WORKS • Set 3–7 directions — short statements of what you're moving toward. • Through the day, log quick "marks" about what you did, on a live half-hour spine. • An AI reads each mark, files it under the direction it belongs to, and returns a one-line signal: did it move you, or not. No categories, no projects, no priorities. Just your directions, what you did, and honest feedback. It is a small, plain tool for intentional living: it does not tell you what to do, only whether what you did matched where you said you were going. A QUIET WEEKLY REFLECTION Once a week, Mark writes you a short reflection on how the week actually moved against your directions — a calm Sunday ritual, not another notification to chase. BUILT WITH RESTRAINT • No points, badges, or leaderboards. • No social feed, no followers, no comparison. • No ads, and no tracking you across other apps. • Dark mode and a considered, typographic design throughout. YOUR DATA Your marks are yours. We collect only what the product needs to work, never sell your data, and let you delete your account and everything in it at any time. SUBSCRIPTION Mark is a subscription with a 7-day free trial. After the trial it's US$9.99/month (prices may vary by region). Payment is charged to your Apple ID; the subscription renews automatically unless cancelled at least 24 hours before the period ends, and you can manage or cancel it anytime in your Apple ID settings.

Verdict
The clearest difference is review sentiment: Mark at 100% against Plankstar's 29%. Mark also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). Plankstar's advantage is monetization model (free with in-app purchases vs subscription). On price, in-app purchases, device support and iOS requirement there is nothing between them.
