Free to receive
It is always free to receive the passwords and notes which you send, so that the process has no barriers for your recipients.
You can send three passwords for free. After that there is a one-time fee of $1 to continue sending.
OK, there is no mention of this on the Apple App Store, and if this is verbatim true, it's the first time I have seen a one-time fee (unlimited use?) for an app. But it does put it in the "free" category.The app store web page for it says "iphone only" but lists iphone, ipod touch and vision (No Ipad?)
It is available on the app store viewed on an ipad, and not on the mac app store at all.
Developer is being done a disservice by Apple because a search for crosspass on the app store substitutes crosspath, showing up to 32 dating apps, and making your click on "crosspass" as if you really meant crosspath.
