Microsoft today announced that they are retiring the Photosynth mobile apps which includes both their Windows Phone and iOS apps. They are retiring it because they think the new Photosynth Preview technology and its cloud processing is a more immersive way to capture a place than the spherical panoramas that our apps produce. If you use the Photosynth Windows Phone App, you can continue to use it, but it will not be updated going forward. And it will be withdrawn from Windows Phone Store. If you have any panoramas stored in this app on your phone, you can upload them to Photosynth.net. Photosynth.net is still maintained and you will be able to view your panoramas online with or without the Photosynth app.
