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.

Verdict

The call

The clearest difference is monetization model: Moon Style at free with in-app purchases against Artemis's subscription. Moon Style also leads on iOS requirement (15.6 vs 17.6). Artemis's advantage is ads (none vs shown) and update cadence (every 2 days vs every 4 months). On price, rating, ratings volume and in-app purchases there is nothing between them.
