Is there any answer choices? Because there are a lot of things you should look at like storage space, you can't download anything if you are running out of space cough* iphone users. And reviews, you don't know if a app is what it says it is based only on the description. You need to read the reviews of someone who has used the application hands on. And this is just a random one but also your virus protection. Can't be too safe when downloading things especially when from untrusted sources unlike Google play and Apple app store.
