Try as I could, I was not able to get this App to stay open for more than 3 seconds after launching on my 3GS 32GB running IOS4.0.01 Given the weather in Hong Kong, there is a No.3 Wind signal up as I write, I would like to think that this will be atleast as good as the other Hong Kong Weather Apps. Assuming that the crashing gets fixed, the next question is why use this in preference to some of the other, excellent Hong Kong Weather Apps? Tried to start again after a couple of hours and it has stopped crashing. The language setting. By default it is preset to Cantonese. In the top right hand corner press the icon that looks like a knife and fork. Its actuallu a spanner & screwdriver. You are now in settings, but it is still in Cantonese. Look at the top of the second second box on the screen. It is full of chinese characters with an arrow on the far right handside side. Press that line of characters (it is traditional chinese for "Language"). You can now selecte either traditional or simplified chinese characters or English. When you select English, every thing in this App changes to English. Frankly, not well designed from the point of view of a non traditional character reader and obviously a feature that needs to be improved. Everything else is very good except for what appears to be a major ommission that the competition offers. I cannot find any push alerts for warnings / alerts from the Observatory. Whilst I accept that this app is free, but so is the competition which does offer all warnings / alerts from the Observatory. Given that this App is the official App from the Observatory, the ommission of push alerts that carry warnings / alerts that are generated by the Observatory is a huge ommission, given that they are provided by the competition. So in conclusion, this is good, but obviously must be improved ASAP just to match the competition. How to be better however is the real question.
