Rememory is a next-generation platform for shooting, editing, viewing, and sharing volumetric video (three-dimensional video in space and time). It creates a new place for video experiences where you can capture and save recordings, performances, and everyday discoveries in 3D, which until now could only be captured in 2D. In addition to creating your own spatial video contents and sharing them with your friends and family, you can also enjoy the future experience of recreating your favorite artists' performances in 3D at home. ■Shoot with LiDAR-equipped devices! With LiDAR-enabled devices, you can shoot volumetric videos (spatio-temporal stereoscopic videos) with Rememory. Enjoy capturing performances, spatial messages, pets, and idea videos, and publish or send them to your friends. ■3D video editing with AR! Rememory's volumetric video can be easily edited in AR. Create your original spatial video by cloning yourself, playing back time, or cropping a part of the video. ■Non-LiDAR devices can also watch volumetric videos! If your device is not a LiDAR device, you can still experience the volumetric videos published on Rememory. Please find the content you are interested in from the top of the app. ■Watch the content from any angle you want. Rememory displays volumetric videos in AR, so you can view the content not only from the front, but also from various angles. ■Take photos and record videos of the content You can take a photo or record a video of the volumetric video you are watching with AR. Create new 2D contents by taking photos of them together.

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 clearest difference is review sentiment: EchoVision at 80% against Rememory's 0%. Rememory's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (14.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
