If you need remote access to your desktop from your iOS phone or tablet, now you can get there for free. Starting today, LogMeIn has a new app in the Apple App Store and it is free. This replaces their low-end Ignition app that they previously charged $30 for. It doesn't give you everything that the current paid app provides, such as file management and cloud storage and HD video/audio streaming. But if you just need remote access, then the free app will do quite nicely. You of course need to run the free version (or the paid version) of LogMeIn on your Windows or Mac desktop, and set up an account online with them to complete the connection.
What I like about LogMeIn is how they are upstanding guys. If you put down your money in the past for Ignition, you will be grandfathered in and have the premium features forever. They are planning on an Android app next year, naturally. The Pro version is $40 a year.
