That’s the thing though - the app isn’t just doing the measuring in my scenario. You’re using either the phone’s AR functionality OR an external, super-precise measuring tool, in conjunction with the app, to rapidly make photo-based diagrams of buildings, floor plans, etc. That’s the selling proposition. Their app description focuses on the tedium of making paper sketches, rather than the measuring per se:
Making paper sketches of objects can be a tedious job. You have to draw the object, add dimensions and make sure others will understand what you meant. Often they don´t. My Measures is a powerful application for storing and sharing object dimensions. All you have to do is take a photo of an object and add dimensions: arrows, angles, photos of details and equip them with text comments for easier understanding.
It’s not a “tape measure” as much as it’s a purpose-built image editor with specific AR functionality, sync, and third-party measuring tool integrations for when Apple’s AR doesn’t cut it.
But you don’t. The benefit of a subscription is that if you’re not using it, you just stop paying. There’s no “lock in” with this, other than maybe the muscle memory of “how I do diagrams”, is there?
This might also be one of the reasons they have a separate app where you pay once for the app, and pay monthly for the features that actually cost them money to run monthly (cloud):
