### 1/5 — Abandoned?

*2025-07-27, version 1.7*

Uninstalled a couple of years ago and just now reinstalled.  I clicked the "restore purchase " link and was informed I would get an email to restore my purchase.  Never got the email.  Uninstalled again.  Abandoned app?

### 5/5 — Recommendations for future updates

*2024-11-06, version 1.7*

It’s a really great app I like using it for multiple things, but I do have a few recommendations that I’m hopeful we added into the future as new features.
1. Surface Fronts
2. High and Low pressure symbols 
3. be able to change the color of land for not just for the United States; but for all countries and continents. Also able to change Lake River and sea color.

*2023-01-23, version 1.6*

### 3/5 — Had it for years, but now…

*2022-11-03, version 1.6*

When I launch it, it crashes. No updates for two years, apparently they want you to buy Seasonality Go for $10 now and I already paid for this app. It was great, before the crashing issues.

### 2/5 — Pain in the keister.

*2020-11-15, version 1.6*

Every time I choose NAM jet stream and low level jet option the app closes. Then on reopening if I don’t take it of that view it closes again. Completely unable to use NAM jet stream low level jet without app closing.

### 1/5 — Force quits

*2020-08-14, version 1.5.1*

Every time after opening the app it closes.

### 1/5 — Developer refuses to fix problem

*2019-09-30, version 1.4*

Problem with precip forecasts blowing up to larger than normal values.  Contacted developer who refused to fix and update.

### 5/5 — Love This App

*2019-01-29, version 1.4*

Update: Appreciate the update!  The load time and refresh time are a lot faster. 

Wow!  Now, I build my maps designed for our specific situation (summer monsoons, downdrops from the Colorado plateau, etc). Love it.  Worth the wait. I use S-Go for quick review, Storm for local storms, and Windy for big picture.

### 1/5 — Hrrr stopped working
