Simple Cycle vs Artemis

Your cycle. Your business. Simple Cycle is a private period tracker for keeping useful records without accounts, ads, tracking, or subscriptions. Period dates, symptoms, and notes are stored locally on your iPhone. We don't collect your cycle or symptom data. There is no cloud sync, Apple Health connection, or automatic sharing. Export a copy only when you choose. START WITH WHAT YOU KNOW Add a period with start and end dates, record an ongoing period, or come back to earlier dates. Edit a whole period without losing its symptoms or notes. Setup is optional: you don't need to rebuild years of history to begin. LOG YOUR WAY Record flow, cramps, mood, and notes on any day. Add custom symptoms, put favorites first, and leave anything blank. An unanswered field stays unanswered. SEE YOUR HISTORY CLEARLY Compare completed cycle lengths and period lengths, with the number of records behind each summary. Browse a dated timeline of symptoms and notes, filter entries, and return to a day to make a correction. YOUR RECORDS. YOUR CALL. Create a readable PDF report or CSV file right on your iPhone. Choose the dates, symptoms, and notes to include, preview the result, then decide whether to share. Export and deletion remain available after your trial ends. Add an optional app lock using Face ID, Touch ID, or your iPhone passcode. ESTIMATES ARE OPTIONAL Show or hide period estimates and choose whether to receive a period reminder. An estimated fertile window is available only if you turn it on. It does not confirm ovulation. Estimated fertile window based on cycle averages. Not a contraceptive. Not for family planning. ONE PURCHASE. NO SUBSCRIPTION. Try everything free for seven days, then keep tracking with one lifetime purchase. No recurring payments. No ads. No tracking. Ever. Built by Under5.

Your cycle deserves better than a calendar guess. Artemis uses your body temperature to detect ovulation through real biphasic shift analysis, the same method used in clinical fertility awareness, powered by intelligent algorithms that improve with every cycle. What you get with Artemis: - Temperature-based ovulation detection, not just date counting - Cycle predictions that learn your unique pattern and tell you when to expect future fertility windows and menstruation periods - Data stored on device, your data stays yours - Handles irregular cycles, missing data, and anovulatory months gracefully - Anomaly awareness: flag sick days, alcohol, travel, or poor sleep - Takes new and historical temperature from any source connected to Apple Health or manual inputs, or operates with no temperature readings at all - Detailed phase visualizations: see the data underlying your cycle analysis - Interactive temperature chart with phase bands and ovulation days - Smart notifications: period predicted, fertile window, ovulation confirmed Partner sharing (free for partners). Share your cycle awareness with a partner through four granular privacy tiers, from phase-only to full temperature detail. You control exactly what they see, and you can change or revoke access instantly. Your partner gets their own view with phase-specific support tips. Your data stays yours. Period. No developer servers. No accounts to create. No tracking pixels. Your health data lives on your device and in your personal iCloud. We never see it, touch it, or sell it. Who Artemis is for: People practicing fertility awareness. People trying to conceive and people trying not to. People who want to understand their body with precision, not approximation. People who refuse to hand their most intimate health data to a corporation. Subscription. Artemis is free to download and includes a 14-day free trial.
