Apple’s devices are good, but developer service is very bad, they reject my app upload due to “one or more reasons”.
I’m now going to upload TidGi mobile app to https://developer.i4.cn (a parite app store), The TidGi mobile app on it will be free (and also Free for me to upload). I will upload to real iOS app store whenever Apple allows me to do, but it will also charge some money to pay for Apple’s 99$ annual fee.
I’m not sure if there is an alternative Free iOS app store for English users, please recommend if you are using some of them.
