Optus Mobile Security
Price: Free trial for 30 days, then $5/month
Do you trust security apps that appear on April Fool's Day? What if I told you it was branded as an Optus app, but it was actually based on F-Secure inside? What if I then mentioned that the telco was going to bill you an extra $5 a month for the pleasure of protecting one of the telco's flagship handsets?
Despite those three questions, fleet administrators may be interested in being able to lock, wipe or reset the passwords of devices, and use the Optus Apps portal to control their fleet. But then why wouldn't those administrators be using a full-featured mobile device management suite?
And the last kicker for Optus is that much of this app's functionality is offered by the handset makers themselves. (But all those annoying "anti-theft" SMS messages from Samsung Apps can wait for another time).
As venerable as the camel book is, the idea of having a quick and offline reference for Perl on a tablet does sound appealing.
I'm sure that there are ways to have the same content at your fingertips for free, but if you can spare the $3, it could be a handy purchase to Perl developers.
This app is another one of those "the first taste is free" type apps. It starts on a 15-day trial, after which it goes into Free Edition mode unless an add-on in Zoho Projects is purchased.
If you think that this is a good purchasing model for your app, I suggest you read a few reviews of this app before you head down that path.
