Ringya, a clever and useful contact-management app for iPhones, is now available for Android devices. It\u2019s free. It does something very cool. And you\u2019re going to want to try it.\n\tiOS and Android have no shortage of apps that manage contacts, allow group texting, and\/or provide contextual caller ID. Ringya does all of these. But here\u2019s what impresses me: Ringya can take a photo of a printed contact list and import the names and numbers into a new "Ring" (or group) within the app.\n\tYou just take a picture, wait a few minutes for Ringya servers to process the image and convert it into contact entries, and it appears within the app. The first time I tried it on my Samsung Galaxy Note, the conversion failed. But I tried again on that phone as well as on my iPhone 5 and it worked beautifully on both.\n\tThe printed list of contacts I threw at Ringya wasn\u2019t perfect, either. The font size was small, and the piece of paper had been folded in several places. A spot check of the contacts the app captured showed complete accuracy.\n\tIn reality, you probably won\u2019t have that many printed phone lists to import. Ringya also imports contacts from your phone\u2019s address book or a Word or Excel document. You can enter contacts manually, too.\n\tThe service isn\u2019t designed for importing business cards, however. Another downside: You can\u2019t choose to import your Ringya contacts into your phone\u2019s address book. As the app\u2019s help section confusingly states: "Ringya places your contact lists in Rings within the application and keeps some contact information in your address book, not as normal contacts; that is, you will most likely not see them at all although they are there." Come again?\n\tOnce you\u2019ve set up a Ring, you can send group texts or emails or call individuals within a group. When someone from one of your Rings calls you, you see some information on them, such as the Ring you\u2019ve added them to. If you share that Ring with the others in it and they later change their contact information Ringya updates their information on your device accordingly. In fact, Ringya will update that contact info for everyone within the Ring, as long as they use the Ringya app. \u00a0\n\tRingya has some room for improvement. But if the developers stick with it and add a little more functionality, it could be a killer contact-management app.
