I have reviewed the new iPhone app tool to help you examine your conscience and then make a good sacramental to a priest (the only way to get absolution, of course).
I pointed out that there were flaws in the app. One of the flaws was that there was no explicit statement reminding people that using this app did not substitute for going to confession to a priest. Perhaps that on the surface seems too obvious to include in the app, but, based on news reports we saw in the last few days, it winds up being a good idea to include it.
The developers have updated the app with a statement toward the bottom of this screen.
They still lack a note about the need to be sure about the penance you are given.
After the screen which shows the list sins you created (in kind, but not in number – the app’s main flaw), there should be a screen that says that the priest may ask questions and/or give advice, and then assign a penance which you should be careful to remember. Then it could move to the screen with your default Act of Contrition.
Again, they need to at least add a note that you should confess your mortal sins in both kind and number.
UPDATE 11 Feb GMT:
I found that you can beginning a phone call, and use the app at the same time. Perhaps there could be a way for the app to be used only when the iPhone is in Airplane Mode.
Also, I found you can use an app such as Audio Notes, to make recordings, and then use the confession app at the same time.
