Main features – Scan and Capture Large Spaces – quickly scan and capture accurately large area of space. Measure and Annotate – measure dimensions of space and objects inside. Annotate easily. Extract and Edit Objects – easily extract objects from scans and save them into personal library. Place Objects in AR View – design and preview using scanned objects in AR View Store and Share Space or Objects – share with friends and colleagues by email, sms and web views. Quantum Summer app and web services enable amatuer and professionals to effectively design and share in 3D
RTAB
This utility app enables real-time 3D scanning and mapping of environments using LiDAR or RGB-D sensors. It features online loop closure detection and map optimization for immediate feedback, with export options for various 3D formats.
- Online 3D scanning and mapping
- Loop closure detection and map correction
- Save maps in DB format
- Export in PLY, LAS, or OBJ
- Multi-session mapping
- AR/VR visualization mode

RTAB-Map (Real-Time Appearance-Based Mapping) is an Open Source LiDAR / RGB-D / Stereo Graph-Based SLAM (Simultaneous Localization and Mapping) approach based on an online incremental appearance-based loop closure detector. The loop closure detector uses a bag-of-words approach to determinate how likely a new image comes from a previous location or a new location. When a loop closure hypothesis is accepted, a new constraint is added to the map's graph, then a graph optimizer minimizes the errors in the map in real-time. An optional memory management approach can be used to limit the number of locations used for loop closure detection and graph optimization, so that real-time constraints on large-scale environnements are always respected. ARKit's visual inertial odometry (VIO) is used as the SLAM front-end for RTAB-Map (the SLAM back-end). * Note that unlike other scanning apps that optimize the map only after mapping, with RTAB-Map you get loop closure detection and map optimization online so you can have a live feedback to know when you have enough constraints in the map for good global optimization before stopping the scan. *** 3D reconstruction available only with LiDAR sensor. Features: * Online 3D scanning/mapping of the environment. * Online loop closure detection and map correction. * Save in DB format (RTAB-Map desktop and rtabmap_ros format). * Export in PLY, LAS or OBJ. * Multi-session mapping (save and continue later). * Use Apriltags to help finding loop closures in textureless environments. * Mixed AR/VR First-Person in visualization mode. * Raw ARKit data recording (up to 60 Hz!), useful to record long sessions without comprising battery life.

Verdict
The clearest difference is review sentiment: RTAB at 100% against Quantum Summer's 0%. Quantum Summer's advantage is update cadence (every 3 weeks vs every 4 months) and iOS requirement (11.0 vs 14.3). On price, ads, in-app purchases and monetization model there is nothing between them.
