Final Fantasy XI, much of it not covered by the in-game interface. There's no easy way to access the all-important airship schedules or the often-loathed Race Specific Equipment quest eligibility. Since the game has been out for several years, there are naturally more than a few applications to track these events... but due to the game's issues with alt-tabbing, they require a bit of a workaround for the player. Now there's another option available to anyone with an iPhone or an iPod Touch -- a new app from Duodyne Studios.
Although not officially affiliated with Square-Enix, the application is aimed at giving players easy access to the most commonly needed timers. That includes a recast timer feature that allows players to simply tap the ability when they use it, followed by an alert on the phone when it becomes ready again. It's not as useful as simple macro checks for short abilities like Provoke, but longer abilities will benefit from having the timer feature. At $0.99 for players in the US and comparable prices for other markets, Final Fantasy XI players might want to take a look.
