Overview

What it is, in plain words.

It adds a biodynamic gardening calendar, solunar fishing and hunting times and tools for astrophotography and stargazing. All calculations run on your device, and the store listing says there are no ads, tracking or data collection.

Is it for you?

Biodynamic gardeners, anglers and hunters, astrophotographers, stargazers and anyone who wants a lunar calendar without an account or cloud service. Solunar times are a planning aid and should be compared with local conditions.

Privacy and permissions

Private by design.

The store listing says there are no ads, tracking, analytics, in-app purchases or data collection, and that the core calendar needs no internet connection. According to the privacy page, location is used only to compute sunrise, sunset and moon times and notifications only for moon and event alerts. Both are optional, and the app works with a manually chosen city.
