Too expensive to purchase

Surely you understand that we are all trying to save money. Charging a premium for the app is counterintuitive

Expensive!

What is it with the annual charge? I don’t have a contract with the weather. A modest one off fee and people would pay it.

Not accurate

Wasted money, miles off the reality of the output and weather forecasts. Nice interface, but defo not worth £4.00 GBP. Let alone £40.

Geometrie stimmt leider nicht

Die App soll den Gesamtertrag von bis zu 4 Teilanlagen mit unterschiedlichen Ausrichtungen berechnen, das ist zunächst vielversprechend. Aber wie kann es sein, dass an einem wolkenlosen Tag mit Sonnenuntergang um 20:40 die Prognose um 15:00 einbricht und um 16:00 auf null ist, trotz Ausrichtung eines Teils der Anlage nach Südwesten? Das kann nicht sein, andere Apps weisen Ertrag bis nach 20:00 aus. Das kann nur auf ein fehlerhaftes geometrisches Modell schließen. Schade.
