You will find that these apps are by far the elite in the iTunes App Store. These are recommended for the iPhone, read on to find out why…
Evernote -Productivity (Free membership offered)
To download the apps for Evernote are free from the iTunes store for iDevice or from their website for PC or from the Mac App Store for your Mac. What this App does is that it lets you sync your notes, where ever you typed them, between your devices. Sign up with them, you can choose the free option or the paid one. The free option is what I chose and I find it really satisfying. The main difference between both memberships is that you can view the notes offline which isn't such a train smash because once you synced from your device, the note is there until you delete it.
You basically use the same log in information on all your devices and it will upload the notes to their servers and you can download them from anywhere on any of your devices which has the same credentials.
