### 5/5 — MERCI ✨

*2026-07-23*

C’est spécifiquement ce que je recherchais

### 4/5 — Excellent but one major flaw

*2026-06-29*

This is a genuinely impressive astronomy weather app with enormous potential. The observing data, weather information and overall concept are excellent, and it is already one of the most capable astronomy planning tools I have used.

There are, however, a few things that stop it feeling like a polished premium application. The logo feels rather amateur for such a sophisticated piece of software, and although I appreciate the reference to Ouranos, the name is not especially memorable or immediately meaningful.

My main concern is the forecast itself. On my app which is the premium version, the weather forecast does not begin until around twelve hours in the future. As an astronomer, one of the most important questions is simply whether it is worth going outside this evening or in the next few hours. I have tried changing forecast models and other settings, but the behaviour remains the same, so it does not appear to be a configuration issue. If this is a bug, I hope it can be fixed. If it is by design, I would strongly encourage the addition of an immediate forecast view, as this would make the app considerably more useful.

Despite these criticisms, I am impressed. The foundations are excellent, and this feels like an application with a very bright future. I look forward to seeing how it develops.

### 3/5 — Widget problem

*2026-05-23*

Widget doesn’t allow west, negative, longitudes.

### 5/5 — One of the Best Weather Apps for Astronomy

*2026-04-14*

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

**Developer response:** Thanks you so much !

### 4/5 — Mostly great app

*2026-03-19*

I find the app really useful, the interface clicks with me. Bortle scale for the map is incorrect and needs fixing.

### 3/5 — Bien mais abonnements

*2026-03-19*

L’application est très bien faites, complète et pratique mais basée sur des abonnements pour profiter des fonctionnalités étendues sur plusieurs jours. Je veux bien payer un achat unique à vie mais pas d’abonnements.

### 2/5 — Has potential but….

*2026-02-07*

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!

**Developer response:** Hello !

This bug has been fixed :) !

### 1/5 — Ouranos - Switch and bait?

*2026-01-03*

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.

### 3/5 — Needs more features

*2025-12-01*

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.

### 5/5 — Great weather, but some aspects of interface poorly tested

*2025-11-27*

Weather tabs are excellent.

Sky analysis graph section is unusable. Tap anything and the legend covers the whole graph so can’t use that. Hard to move away when legend is up. Graph hogs half that screen for no reason even when scrolling down. 

Move weather back to front and centre of the app - that’s why I’m using it, not for community photos, that’s what reddit is for. 

The app is super useful, please don’t clutter it up. Focus on the core function and get that sorted.
