FAQ
A biodynamic moon calendar connects the lunar cycle - a synodic month of about 29.53 days - with everyday activities such as gardening, haircare, and rest. Traditional biodynamic practice divides the cycle into waxing and waning halves: waxing periods are associated with growth and vitality, while waning periods are associated with settling, pruning, and rest. MondPlan turns this practice into a simple iOS app.
MondPlan is a one-time purchase. There is no subscription, no recurring fee, and no required in-app purchase. Pay once and the full app, including all moon phase features and home screen widgets, is yours.
No. MondPlan is privacy-first: it does not collect personal data, does not create an account, does not track you, and does not use advertising SDKs. Your moon phase data, sleep notes, and mood entries are stored locally on your device only.
MondPlan tracks all eight primary lunar phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent. It also shows the current illumination percentage and the countdown to the next phase.
In biodynamic tradition, the waxing moon (from New Moon to Full Moon) is a good time to sow seeds, plant, and transplant, because growth energy is believed to rise. The Full Moon favors harvesting, while the waning moon (from Full Moon to New Moon) is often used for pruning, weeding, and soil work. MondPlan marks these windows on a calendar so you can plan garden tasks around them.
