## What is NimbusWx?

NimbusWx is a spot forecasting tool that visualizes the numeric model data from the weather computers used by industry experts. It's powered by the incredibly popular website SpotWx, which is used by professionals all over North America and the world. 

***New in Version 1.2: Create your own custom AI weather forecaster - powered by chatGPT

The difference between NimbusWx and other weather products is that we've lifted the veil on forecasts by giving you access to the raw weather data. That raw data is normally inaccessible because it requires special desktop software to open and interpret, we take that data and turn it into a human friendly visual format so you can make forecasts like a pro.  

NimbusWx features include: 

- Customizable AI weather forecaster. You can control what type of weather data you want to know about, and how the forecaster behaves.

- Select any coordinates on Earth. 

- View and compare multiple weather models for your coordinates. 

- Save your favourite places for fast viewing. 

- See the models simulated altitude, and spatial / temporal resolution. 

- View advanced weather metrics. 

Models currently available on the mobile version:

- GFS (Global Forecast System)
- RDPS (Regional Deterministic Prediction System)
- HRDPS Continental (High Resolution Deterministic Prediction System)
- HRDPS 1km West (High Resolution Deterministic Prediction System)
- GDPS (Global Deterministic Prediction System)
- NAM (North American Mesoscale Model)

### 4/5 — Nice interface for the full featured spotwx website

*2025-08-16*

2 yr user. I use NimbusWx for quick spot location forecasts. Usually for same day activities. The AI feature is merely ok. It needs a precise prompt to give a useful forecast. My best prompt is ‘detailed 24 hr forecast’. The AI feature hasn’t worked for the last month or so. :/

I wish the app had a feedback link instead of relying on Facebook (which I no longer us)

All round decent app!

### 2/5 — Needs access to different mb FCs

*2025-05-12*

The concept is great but the lack of ability to access weather for different mb levels on the models removes any usefulness for me. Will happily subscribe once I can access the different pressure levels on models.

### 2/5 — Not quite ready

*2023-04-30*

Could be better. Graph details are lacking. Was hoping for more of a SpotWx look. Would like to cancel pro version subscription but no option to do so?

**Developer response:** Which graph details were you hoping for? I'll add them if you keep the pro version ;)

If you decide you don't want it, you can unsubscribe in your iPhones settings > Purchases / your profile >  Subscriptions

### 3/5 — Interesting concept, but < spotwx

*2023-04-12*

On the GFS model (10 days) I can’t see days of the week on the graph. When I click and drag on the graph, the date appears but still not the day (monday, tuesday, etc) 

Also, an integration of the Nowcast stations data would be nice! 

Lastly, a better topo map underlay would be nice to see the selected altitude. Currently, only way to know is once you’ve selected your model. 

Lots of potential, i’m real close to buying the pro version.

**Developer response:** Hey Jack, 
I really appreciate the feedback! I'm working on a big update right now and will try to include the contour lines and also the days of the week.

It's hard to fit all the data into a small screen, but I should be able to squeeze it in, if it means you'll get the pro version :)

### 3/5 — Almost perfect

*2023-04-11*

Needs just one feature from SpotWX which I use heavily - timestamp for when the model was most recently updated! So vital.
Otherwise, looks great.

**Developer response:** Hey there, thanks for the feedback. I'll add that to the next update :) 

-Ben

### 5/5 — Just what I needed!

*2023-04-05*

Works fast and shows the models I want to see. Looking forward to future additions to this new app. Thanks!

### 5/5 — Wow

*2023-04-02*

Very cool app

### 1/5 — Needs much more functionality

*2023-03-31*

Useless until units of measurement (including time) are clearly shown and can be changed.

**Developer response:** Hey there, you can actually tap and drag on the charts to see a pop up with the time and units :)

-Ben

### 2/5 — Doesn’t show models

*2023-03-31*

No matter what location I choose in Canada or the US it doesn’t list any models to view so not very useful

**Developer response:** Hey there, we had a bug yesterday with the SpotWx backend. It was resolved and shouldn't happen again. The spotWx website was down as well, but everything should be good to go now :) 

-Ben

### 1/5 — No models.

*2023-03-30*

Paid for the pro version. Currently have zero models showing for anywhere.

**Developer response:** Hey there, there was a problem last night with spotWx backend. The spotWx site was also down this morning as well. The issue has been completely resolved and shouldn't happen again. Please take another look and reach out to me if you have any other issues
