EchoVision is an interactive mixed reality art experience that simulates bat echolocation using custom-designed, handheld, bat-shaped masks based on the open-source HoloKit headset. As users initiate sounds, they experience echolocation—the remarkable navigation method bats employ in darkness—through visual representations of propagating echoes mapped onto the real-world 3D shape of the surrounding environment, scanned in real-time by the LiDAR sensor of a smartphone mounted on the masks. By providing a unique glimpse into how non-human creatures perceive their sensory world, EchoVision promotes an ecocentric design perspective, fostering interspecies understanding and appreciation.

Verdict

The call

The clearest difference is in-app purchases: EchoVision at none against VirtualFriend's 4. EchoVision also leads on update cadence (every 2 months vs every 24 months) and rating (5.0 vs 4.8). VirtualFriend's advantage is review sentiment (95% vs 80%) and ratings volume (20 vs 2). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

EchoVision holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: VirtualFriend has 20 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 95% of VirtualFriend's written reviews are positive against 80% of EchoVision's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

VirtualFriend ships an update every 24 months, EchoVision every 2 months. The most recent releases landed on September 18, 2026 and June 5, 2026 respectively.
