### 4/5 — Most straightforward weather app

*2025-04-05*

However I can’t delete bookmarks once they are created. The app crashes instantly when I try to delete them

**Developer response:** Hi Azukisoba, kindly contact me at simsdev.app@gmail.com , i can delete it from my database. 
Sorry for inconvenience.

### 2/5 — Paid for the removal of ads but it won't work

*2016-11-08*

Please check on the app. I paid for the removal of the adverts but it won't remove it.

### 4/5 — Good Apps

*2015-09-16*

Very beautifully designed apps.

### 2/5 — Previous version much better

*2013-10-04*

Too bad changes were made. Previous version much easier to read and manage--easier to swipe around the island, gave the necessary info in one shot, albeit a little cartoonish in graphic design. But so what? The essentials were there. New version is just like a normal weather app, but more difficult to navigate. Zooming is choppy and frustrating to control, too many 'layers' that cloud the basic info you want (temp & weather radar). Could the previous version have used a couple of tweaks? Sure. But completely changing the main format and graphics is a bummer.

### 3/5 — Not bad but limited capability

*2013-08-15*

Somewhat limited in options. Can't zoom in. I would like to see a 5 to 10 day outlook page.   I will use it to see current conditions only.

### 3/5 — Ok

*2013-07-02*

The distribution of pollution doesn't show most of time:(

### 4/5 — Great app

*2013-06-21*

Very informative app with really detailed local forecasts. 

Would have given the app 5 stars if there was a paid version to get rid of the ads and if it opened and refreshed quicker.

### 3/5 — So so

*2013-03-31*

Not easy to use.

### 1/5 — SG Weather

*2013-02-26*

This app is very poor and very amateurish compared to say Weatherzone +. With Weatherzone + you get rainfall radar, the weather forecast for the next 24 hours, including the % chance of rain, and statistical data for the last 48 hours. The only problem is that it focuses on Australia & NZ only gives scant coverage of Singapore.

### 4/5 — Great app - sadly no iPad version

*2013-02-19*

This is a great app, especially in SG's changing weather. It is just a shame there isn't a native iPad version yet. I would get it ASAP especially for the added resolution :-) - developer if you listening :-)
