Read full description

Memo, tasks, calendar, and health — the four apps you open every day, now one. Utility brings together notes, a to-do list, your calendar, and simple health tracking (weight, body fat %, steps) in a single app. No ads, no network calls except iCloud sync and the App Store. Works on iPhone, iPad, and Mac. Notes and tasks sync through your own iCloud; health records never leave the device and are not stored in iCloud. Memo Create, edit, and delete notes freely. Pin the ones you need close at hand. Tasks Keep a to-do list with due dates and reminders. Calendar Synced with your device's own Calendar: see your existing events alongside your notes and tasks, and add or edit events right from Utility. Health Log weight, body fat % and steps by hand, or read them from the Health app (iPhone and iPad). BMI is calculated from your height, and charts show the trend over time. Your data Back up notes and tasks to iCloud and restore anytime. Choose Light, Dark, or System appearance. Free to use Save up to 10 notes, 10 tasks, and 10 manual entries of each health metric (weight, body fat, steps) for free. Utility is made by one independent developer — if it earns a place on your phone, the yearly Supporter plan (auto-renewing subscription) or a one-time purchase (pay once, no renewal) removes the limits, adds CSV export, and keeps development going.
