Onelink.to is a web based service for smart download links that simplifies the distribution and downloading of apps for mobile devices.
Instead of needing multiple download links or QR codes for your app, you only need one smart download short link (or QR code) from Onelink.to.
You add the download links to Google Play, Apple AppStore, etc; and we make sure to send each user clicking the smart Onelink.to link (or scanning the QR code) to the correct app store/marketplace depending on what device is being used. Or to your homepage or similar if it is not a mobile device (using a "Fallback URL").
Onelink.to launched in 2011 and is one of the first services offering smart download links.
