Dropbox for iOS does a wonderful job in the cloud. But now there’s competition in the form ofGoogle Drivefor iPhone and iPad.

Like Dropbox,Google Drivelet you access your files that have been uploaded from a Mac or a PC.

To begin, you need to download the app from the iTunes App Store and install it and then sign in with a username and a password. This is the easy part.

Now starts the Captcha deal. First you will need to enter a Captcha and your password again. That is not too easy. The iPhone screen’s pretty small for fitting keypad and Captcha and the input area. You will then be directed to a second welcome screen. You need to hold your phone in the landscape mode to read it. You need to supply a mobile phone number or email so that they can send you a reset code in case you forget your password.

Once you are through, you can start using theGoogle Drive. And it works reasonably well.

Basically, both Dropbox andGoogle Drivedo the same thing, share files via synching to the cloud. But Dropbox asks your username and password only once and there’s no Captcha headache here.

However, Dropbox has started an intercept strategy on the Mac to get photos uploaded to its cloud store. An iPhone sync session gets you one of these annoying intercept windows. Google Drive , thankfully, is free of that.

So will you stick with tried and tested Dropbox or go forGoogle Drive?
