Qlone 3D Scanner 4+

Of all the 3D scanner apps this one was by far the best I found for small objects

App app is an example of deceitful design, supported by willfully misleading app feature documentation: Qlone allows for 3D scanning through photogrammetry, and provides a visual identifier for when the camera is in range to build data points needed for the model’s surface. However, the app design intentionally prevents the actual model produced from being seen until a forced paywall subscription is authorized. It’s clear why, as every scan made is lumpy & misshapen - all promotional app material emphasizes models texture maps as a way of disguising the lack of usable resolution.

It is misleading to sell an app purchase for fine detail on small objects without the capacity to provide this service, or for the user to evaluate this quality before forcing payment. A further up sell is suggested by the Qlone app for additional, undefined features in their ‘educational’ app version - but only after the user experiences their first model. This suggests a way of fixing the shortcomings of the ‘paid’ add-on while marketing the sale of the same product twice.

It’s interesting to note as well - for initial scans made prior to the Premium unlock, the registration grid has a tendency to display as blue, filling in the quadrants with ease. However, after the purchase is made and any finished scan can display, there was an overwhelming shift toward red grids & scans failing. It might require a code review to prove, but from my experience today, it felt like the free version had UI tweaks to suggest quality & ease of use that were not present in the actual product.

For an app that markets its self as a scanner of small objects, it fails at this under optimal lighting conditions with both horizontal & vertical registration mats / and under both photogrammetry methodologies (stationary object, rotating camera / rotating turntable with object, stationary camera).

I have requested a refund of the ‘premium’ $21.99 add on that offered higher resolution scanning and model export, and recommend others steer clear of this app until the above design issues are addressed.

From the moment I downloaded this app, it started showing me a live activity countdown with the duration until my “premium discount expires”. This displayed in the Dynamic Island as well as the Lock Screen, and was not dismissible (other than at the system level).
