visual storage scans any QR code (version 1 to version 40) and saves the data payload contained in the QR code as a file on your iPhone. With modern compression technology, photos and even short videos can be stored directly on QR codes. As such, this app works as a form of visual file delivery without an internet connection. If the file is ≤2,953 bytes, it can be stored on a QR code, and it can be scanned by visual storage. Such files can include, but are not limited to: JPEG - .jpg PNG - .png GIF -.gif JPEG XL - .jxl AVIF - .avif HEIC - .heic MP4 video - .mp4 MOV video - .mov AV1 IVF - .ivf VVC video - .vvc WAV - .wav MP3 - .mp3 FLAC - .flac Ogg - .ogg Lyra audio bitstream - .lyra Codec2 audio bitstream - .codec2 ZIP - .zip PDF - .pdf and more. visual storage can be used without an internet connection once downloaded.

SCANNING Memo exports high-accuracy, COLMAP-compatible capture data, ready for training on your PC with the 3D reconstruction pipeline you prefer. Memo refines ARKit camera poses to improve tracking accuracy and uses diffusion-based depth estimation to generate detailed geometric priors. This reduces reliance on LiDAR and helps 3DGS training converge faster with more stable initial geometry. Memo works on any AR-capable iPhone. On supported Pro models, LiDAR-assisted capture can also be enabled in Settings. ON-DEVICE TRAINING Train 3D Gaussian Splatting scenes entirely on your iPhone. Memo is deeply optimized for Apple hardware, delivering fast, high-quality local reconstruction without sending your captures to external servers. Choose a preset for a quick start, or adjust training parameters for greater control over the final result. Once training is complete, export a camera-path video or scene file directly from your device. You can also upload your scene to SuperSplat with one tap. PRIVACY FIRST Your captures and reconstructions stay on your device. No cloud processing, no mandatory uploads, and no account required.

Verdict
The clearest difference is in-app purchases: visual storage at none against Memo 3D Scanner's 1. Memo 3D Scanner's advantage is iOS requirement (18.0 vs 26.2). On price there is nothing between them.
