SnapSize is an app that allows you to measure the length of objects captured by the camera at any time, whenever you need. It enables you to store both the camera images and 3D data together, so if you're unable to measure immediately or if you made a mistake in selecting the measurement point, you can use the app to measure later. The results of your measurements can be saved as images, making it easy to share information or add them to documents. [Main Features] ・Capture and save the data. ・Measure distances anytime by using the saved data. ・Output the results of depth since 3D data is saved. ・Save and share captured data and measurement results.

Verdict
The clearest difference is ads: SnapSize at none against くじら尺's shown. SnapSize also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). くじら尺's advantage is update cadence (every 2 months vs every 6 months). On price and in-app purchases there is nothing between them.
