I heard exams will start on Saturday how true is this information and if is true where can we go to write it

Depends on the app. You have to take into consideration such factors as whether the app will be hybrid (browser based) or native (relies on core phone functionalites) ...will it require a backend? will this backend be so data intensive you will contemplate using cloud services amongst others. Also, are you doing it with a company (500k and above but you get great after-deployment support, speed, assurance and other perks) or an individual developer (100k upwards).

Anyway, I charge 150k to 300k for native android apps. excluding hosting costs. The price shifts forward based on the number of object classes I foresee the app will require. (more classes, more complexity).

Finally, speaking from experience, its not wise to do an app for IOS, Android,Windows, e.t.c at the same time. You should target one platform and if you succeed on it, expand.

To create an app goes for 150 to 300k what about a website
