Sync: Plan and Actual is free on App Store

Sync: Plan and Actual is an iOS app that usually costs $4.99 on the App Store. Right now it's free to download. Going by the name, it's a planning tool for setting out what you intend to do and checking that against what you actually did.

It's worth a look if you plan your days on an iPhone and want to see how closely your schedule matches reality. No end date has been given for the free price, so grab it soon if you're interested.

Paid App Store apps you get for free are normally tied to your Apple account. Once you've claimed it, you should be able to download it again later from your purchase history, even after the price goes back up.
