PricePer.  This app is designed for Americans traveling elsewhere, and for others traveling to the United States of America.  It performs a "double conversion" of unit and currency; for example, if gasoline is $3.50/gallon, what's that in €/liter?  

There are three important views in Price-Per.  The first is the view on which the conversion takes place.  After the price field has been entered, the currency chosen, and the units chosen, tapping the down-arrow button will post the converted price-per.  Tapping the curly-arrow button will reverse the conversion (for example, if gasoline is €1/liter, what's that in $/gallon?)

On the currency page, choose among about 60 currencies.  On this page you can also edit an individual currency exchange rate, or download new values for one or all exchange rates.

On the units page, you can choose the units which go with the U.S. dollar ($, USD).  There are units for length, area, mass or weight and volume. 

The app works for all models of iPhone and iPod Touch (and for the iPad emulating an iPhone); it behaves properly in both landscape and portrait orientation.  It works for iOS versions 6.x and 7.0.  Internet access is required for the "download new exchange rates" feature. 

About Exchange Rates.  The exchange rates in the app were current at the time the app was sent to the iTunes App Store.  It might be a good idea to download all new exchange rates as soon as the app is installed, and then to download individual exchange rates, or edit exchange rates, before or during a trip.  The exchange rates are obtained from a ExchangeRate-API.com; internet access is required to download new exchange rates, and therefore may incur a cost to the user.  As currencies are added or deleted, revisions to the app will be required.

Stations of the Cross at St. Thomas  Welcome to the Stations of the Cross, or the Way of the Cross, at St. Thomas Episcopal Church, Lancaster, Pennsylvania.

This app, for  both iPhone and iPad (iOS 7) allows the user to experience the Stations of the Cross in the sanctuary of St. Thomas Church.  Of course, one can use the app without coming to the church as well.  

You can read a meditation taken from the Episcopal Church's Book of Occasional Services, and pray the stations by yourself or with a group.  There is no voice-over for this meditation . You can also read a meditation designed for younger people.  With this meditation, you can choose to hear the words of the narrator and the words of Jesus.  Finally, you can read (and hear) the comments of the artist, Virginia Maksymowicz, who designed and sculpted the stations for St. Thomas.

You can always choose to turn on or off the voice-overs or the brief phrases of music which accompany each station.  However, given that the sculptures in St. Thomas church are meant to be touched, the entire experience is accessible to the blind or visually-handicapped.

If you are in the sanctuary of St. Thomas, the app can tell which of the stations is closest to you.  It will ask if you want to see and read that station.  To use this technology, you must turn on Location Services and Bluetooth, and you must be running iOS 7.  The app appears with this feature turned off in an effort to save battery life; when you come to St. Thomas church you will be invited to turn this feature on.  You can always turn it on or off as you need.
