After your message is ready, you can choose who to send it to. Slingshot gives you the option to select multiple recipients, which a handy feature. You can choose to save the images or videos you capture yourself to your camera roll, but the messages disappear, although someone might screenshot your photos and you'll never know.
Slingshot isn't a must-use app, especially when Facebook already offers you Facebook Messenger and WhatsApp. It lacks the spirit and ingenuity that the network's Creative Labs team put together with Paper. And the world doesn't really need more ways to send disappearing messages. But Slingshot is a better option than Poke, and maybe that's all Facebook was aiming for.
