### 2/5 — Abandonware - DO NOT BUY

*2023-08-16*

The (free!) app you should get instead of this is Field Guide to Clouds. First of all, the developer has clearly abandon this app as it isn’t updated for 2019 or newer iPhones that have screen notches or “islands”. You SHOULD NOT pay for this unless they update that at least. (I did simply out of curiosity.) It does technically contain information about clouds but it’s not particularly useful as an app. It does have a nicely designed intro so it’s too bad they didn’t extend that thoughtfulness into making the cloud info and identification better.

### 2/5 — Bro

*2023-01-14*

I payed 1.99 to look at some pictures!!! I thought this would be some kind of cool cloud camera app I’ll give it 2 stars just for the cool pictures

### 1/5 — lol

*2020-02-08*

Je n’ai pas voulu juger l’appli avec précipitation, mais elle s’avère aussi nulle qu’un cumulonimbus.
Bref on est pas là pour parler de la Chine et du Bhoutan. 

Bon vent

### 1/5 — Worst app ever

*2019-09-15*

Just a few pictures of clouds that I could find on the internet. No other functions. Waste of my money.

### 5/5 — I’m so smart

*2019-05-19*

My friends think I’m so smart when I name the clouds. Name-dropping with nature and the weather. Smarter than saying “fluffy” or “rain clouds”.

### 5/5 — Lovingly crafted reference guide

*2019-02-13*

It’s great the developer continues to support the app some seven years after releasing it.

Not much to it: clouds and selected weather phenomena, pictures and brief descriptions. At a basic level, I wouldn’t change a thing. It’s accessible and utilitarian. 

If I were to nitpick however: It could use a little proofreading in the descriptions, but from what I understand, English is not the developer’s first language, nbd. Metric conversions would be nice for us savages that still use feet and fahrenheit. Also, common iOS gestures such as swiping left edge to right to go back and a downward swipe to exit a picture aren’t supported. On notched iPhones, the back button is partially obscured and not in the display’s safe zone per Apple’s Human Interface Guidelines. 

Otherwise, it’s a great app, honest in function, with a no nonsense pay-once price.

### 4/5 — I’ve loved this app forever...

*2018-05-24*

But because it’s been around for so long, they really need to update their images. The beautiful images look so low quality on current screens. Still, useful and I adore it.

### 4/5 — Very well done

*2018-05-17*

This new update works without a problem, bug free. Nice app with good descriptions of cloud types. Landscape mode not included but would benefit iPad users. Good job!

### 5/5 — Super

*2018-05-17*

Très intéressant et pédagogique. Application bien réalisée

### 1/5 — Not enough education

*2018-05-17*

Even in this app they have a actually picture of a Plane Contrails. They dissipate the Ice When the sun is out. Gov/CIA already admitted they spray toxins they change name to aerosols atmosphere injections if you don’t cover it then I think it is a CIA app
