5/5One of the Best Weather Apps for Astronomy
Ouranos is one of the best ways to plan your night under the stars. I’ve been using this app for over six months and have appreciated my communications with its developer. Paul does a great job with this app and updates it often! Michael, Late Night Astronomy

3/5Needs more features
The data given is useful. Seeing, temps, cloud%, etc. However, there are free alternatives out there that do just that. There needs to be a difference maker on this app that makes me want to pay $40/year.

3/5Widget problem
Widget doesn’t allow west, negative, longitudes.

2/5Has potential but….
This looks to be a great platform. My biggest issue is you can’t search for deep sky objects. If you use their name or scientific designation, it is empty. I paid for the pro version and it is no better. Please fix this app!

1/5Ouranos - Switch and bait?
I had purchased Ouranos Pro by this developer. Looks like they have abandoned it and instead switched to a subscription model. This is not good. I am not happy that they took my money and now killed that product.
