Best iPhone apps this week

Temple Run: Brave 69p
Temple Run addiction? We can empathise. Now Pixar's getting in on the action, setting Brave's feisty princess Merida against the dangers of the forest – looks like we'll be hitting the app store for another round. The gameplay sticks to what we know and love, but does include a few nifty new features – including a bow and arrow so you can fight back as you dash. Well, it wouldn't do for Merida to just run away, would it?

Celebrating Frogger's 30th anniversary (how he's managed to live so long is beyond us) the new game offers a choice between retro or HD visuals. How does he keep getting stuck on the wrong side of that road?
