A little self-promotion, so to speak. 🙂
I’ve just released WhatsHare, a simple little app to share links and text across Android devices, or from Chrome on your PC/Mac to an Android device.
Of course, I only discovered chrome2phone after I was already done writing the app. Luckily, they’re a little different. My little app exists to make sharing links using any sharing app (any IM app, email, clipboard, whatever accepts text), whereas Google’s app is more to share links with browsers. Also, the reason why I started writing the app in the first place was to let me share stuff with my friends on Whatsapp, and that’s waaaay more easily done with my app than with Google’s.
The app uses Google Cloud Messaging to forward messages (it’s very fast!) and Google’s URL shortener to pair devices (GCM IDs are encrypted with a randomly generated key that’s communicated using a QR code encoder/decoder).
