Jammy Guitar, a futuristic-styled travel guitar, is set to launch next month. For the next 4 days you can pre-order it for $400, down from $600.This is an actual guitar, not just a controller like the Jamstik. You can plug it directly into an amp and start playing. It also includes a USB-C connection if you want to get MIDI out of it.
They've already released an app on the app store, but here it shows its Indiegogo roots by over-promising and under-delivering. The promo shows the app with a lot of great features; like being able to tweak the tone of the guitar from the app, and record your performance in MIDI. Neither of these functions are mentioned on their website, nor the iTunes description for the app, so I don't think they'll make it for release.
