DailyQuad is a free iPhone habit tracker built around four daily goals and a 365-tile year wall that shows your whole year on one screen. Rest days are planned in, so a rest day never breaks a streak. Goals can auto-fill from Apple Health, and an optional GLP-1 module handles dose logging, injection-site rotation, symptom tracking, and a one-page Visit Summary PDF for your prescriber. There is no premium tier, no ads, and no upsell — the whole app is free.
