Milestone is a private, offline commitment tracker for people who want to actually follow through. Design your own challenge — 7 to 365 days — with the daily rules that matter to you. Wake before 6. No alcohol. Read ten pages. Move for thirty minutes. Whatever you're committing to, you set the terms. Each day, complete your actions and deliberately "keep" the day with a press and hold. Milestone records it. Watch your streak build, your milestones unfold, and your progress fill in — one kept day at a time. Choose how strict you want to be: • Strict — one missed day restarts the count. • Flexible — a couple of grace days absorb a slip, so a single off day doesn't erase your run. REQUIRES A ONE-TIME PURCHASE Milestone is a paid app. Starting a challenge is a one-time in-app purchase, priced by length (from $3.99 to $29.99) — there is no subscription and nothing auto-renews. You buy a challenge once; when it's finished you can start another (returning finishers get a reduced price). A purchase is required to create and run a challenge. Private by design. Everything stays on your device — no account, no login, no feed, no ads, and no data leaving your phone. Just you and the commitment you made to yourself. Make the promise. Keep your word. Prove you can follow through.

Verdict

The call

Atoms's advantage is ratings volume (11K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

UpkeepUpdate frequency
