HoloKit X is a simple, affordable accessory for iPhone that unlocks the world of stereoscopic AR and allows people to Dream Together in new realities. Download the HoloKit X app, follow the simple instructions to pair iPhone, try out a few of the included realities, and then get ready to transport into a new reality to become a wizard or dragon hunter and play with friends. The HoloKit X app includes all content, a series of realities, to demonstrate the capabilities and wonder of stereoscopic AR, experience immersive art dreams created by world-renewed digital artists, and battles with wizards and dragons by casting spells. HoloKit X’s killer feature is face-to-face multiplayer, which allows friends to battle together or against each other as wizards, by casting spells, and hunt down and battle dragons together. This has never been done before with AR and is now available for anybody to use. The HoloKit X app also enables others, with their own iPhone or iPad, to Dream Together with their friends using a unique spectator mode feature where battles, dragon hunts, and immersive art experiences can be viewed in real-time from a second screen. Simply download the app and await a pair request from a friend or friends with HoloKit X (using AirDrop). The HoloKit X app, once iPhone is docked and paired, includes simple controls to switch between realities. The included Apple Watch app enables motion control within HoloKit X realities with any object and using the built-in gyroscope. Now any object you want can be your wand to cast spells in these new worlds and shared experiences. The app also integrates with the Health app on iPhone and Apple Watch, allowing dreamers to track their activity and achieve fitness goals through individual battles and with their friends.

Verdict

The call

The clearest difference is ads: Brainwave Visualizer at none against HoloKit's shown. Brainwave Visualizer also leads on monetization model (free vs ad-supported) and iOS requirement (7.1 vs 17.0). HoloKit's advantage is update cadence (every 7 months vs every 42 months) and review sentiment (67% vs 58%). On price, in-app purchases and device support there is nothing between them.
