Snapchat has released an update on iOS and Android that brings two new features.
The first is Lenses. Now in the selfie mode, you just press and hold on your face, which triggers the facial recognition. It then enables multiple effects that appear at the bottom that align to your face and animate. There are several Lenses available at the moment and we expect more to be added later. On Android, this is device specific, so it doesn't work on some devices.
The second feature is paid replays. Previously, you could replay a snap sent by someone but you could only use one replay per person during a day for some reason. The reason seems to be clear now, because Snapchat now allows you to purchase extra replays, where you can get 3 replays for a dollar. This is an absurd way to make money but then Snapchat has always been absurd.
