So much promise, but ...

I love the way this app brings biodynamics into the mainstream. It also helps people understand why the same wine can taste amazing one day and be underwhelming another day.

But try as I might, the app doesn't let me purchase the upgrade. Can someone on the team please share a link? Thanks!

Biodynamic Wine

I love the biodynamic principals of wine - it’s the planting, growing, harvesting & making of wine based on the cycle of the moon. It’s very cool. Our bodies are 70% water, and greatly affected, like the tides of oceans by the moon, as is everything. Wine tastes different based on the lunar calendar.

I bought the app last year and again this year. Cannot rave about it enough.

Not worth any money

This app unfortunately isn’t worth the paywall it is set behind. Limited data, awful interface, old UI. Skip it and just set yourself a google search widget on your Home Screen and you can get twice the data.
