How we compared
Every row in the matrix below is a verifiable fact: pricing and features are taken from the public App Store listings (accessed August 2026). Where a competitor does not advertise a capability, the row shows “not stated” rather than a guess. Moon phase accuracy for all four apps is based on standard astronomical algorithms (e.g. Jean Meeus, Astronomical Algorithms, ch. 49) and is not a differentiator.

Frequently asked questions
What is the best moon calendar app for iOS?
It depends on your needs. MondPlan is the only one with a one-time purchase (no subscription), full privacy (100% local storage, no tracking), and dedicated gardening, haircut and sleep trackers. Moonly adds astrology and meditation but is subscription-based. MoonX adds weather forecasts.
Are moon phase apps accurate?
Yes - the major apps all compute moon phases from standard astronomical algorithms (e.g. Jean Meeus, Astronomical Algorithms ch. 49). MondPlan documents its method and states +/-1-2 minute accuracy.
Which moon calendar app has no subscription?
MondPlan is a one-time purchase with no subscription and no recurring fees. Many competitors (Moonly, etc.) require monthly or yearly subscriptions for full features.
Which moon calendar app is best for gardening?
MondPlan includes a biodynamic gardening calendar (sowing, harvesting, pruning by moon phase) out of the box, based on the Maria Thun tradition. General moon apps show phases but rarely include per-crop guidance.
Which moon calendar app is most privacy-friendly?
MondPlan stores all data locally, has no account, no ads and no tracking SDKs. Some competitors state they may use identifiers to track you across apps (e.g. Moonly).
