Auer Circle vs Red Diary

Auer Circle is a minimal meditation timer that focuses on easy of use and a simple interface. Select the duration of your session by tapping the bottom left, and then tap start. That's all. You can track your sessions per day.

A period and cycle tracker that keeps your data on your phone. No account. No cloud. No tracking. No ads. Most period apps send your most private information to their servers. Red Diary doesn't have servers. Free to track your cycle, log symptoms, and get predictions — no trial, no card, no expiry. Premium unlocks the fertility, pregnancy, and insight modes. PRIVATE BY DESIGN Your cycle history, symptoms, and intimate details never leave your device. There is no account to create, no server to breach, and no company reading your data. Export anytime for a doctor's visit or your own backup — it's your information. BUILT FOR REAL CYCLES, NOT AVERAGE ONES Most trackers assume a textbook 28 days and get confused when yours doesn't cooperate. Red Diary reads each cycle on its own terms, so irregular, long, short, and changing cycles are understood instead of flagged as wrong. BODY WEATHER Your own forecast, built from your own logs. Red Diary looks for patterns across your history and tells you what today has tended to look like for you — sunny, clear, mixed, overcast, or stormy. If it doesn't have enough history to say something true, it tells you that instead of guessing. WHAT SHOULD I DO TODAY? Every time you open the app, you get an answer. Phase-aware guidance for movement, food, and rest that shifts as your body does. FOUR MODES Track My Cycle — phase-by-phase analytics and predictions Trying to Conceive — fertile window, peak day, cycle health, and support through the two-week wait Avoid Pregnancy — honest fertility status, including the days it can't be certain about I'm Pregnant — 40 weeks of content, kick counter, appointments, and trimester insights Switch whenever life changes. The app changes with you. A CALENDAR THAT ACTUALLY WORKS Start and end your period with one tap, right from the calendar. Backdate cycles you missed. Log intercourse. See period, predicted, fertile, and logged days at a glance — with moon phases, if you like tracking alongside them. WHY YOU FEEL LIKE THIS Log symptoms, mood, sleep, temperature, and more. Red Diary finds what repeats across your cycles and explains what's behind it, instead of just recording it. SHARE HOW YOU FEEL Send a phase-aware note to a partner, a friend, or your birth control buddy through iMessage, WhatsApp, or anywhere else. No accounts, on either end. ON YOUR WRIST Cycle day, phase, and progress ring on your watch face in phase-matched colors. Start or end your period, log your mood, and get guidance without reaching for your phone. APPLE HEALTH Steps, calories, exercise, and sleep flow in automatically. See how your energy and activity really shift across your cycle — no extra logging. BIRTH CONTROL REMINDERS Pill, patch, ring, shot, IUD, or implant. On-time reminders, streak tracking, and insights that adapt to your method. WHAT'S PREMIUM Trying to Conceive, Avoid Pregnancy, and Pregnancy modes, Body Weather, full cycle insights, fertility analytics, and mood sharing. Cycle tracking, logging, predictions, calendar, and birth control reminders are free and stay free.
