One-time purchase and introductory pricing details
¹ Lifetime purchase: "Lifetime" refers to the lifetime of the app, not the lifetime of the purchaser. The one-time purchase permanently unlocks all Pro features for as long as the app remains operable on your device in a compatible version. Online components (cloud backup, cross-device sync, LensCode sharing) depend on the continued operation of our backend infrastructure (Supabase, Vercel). Should these services need to be discontinued or restricted, local use of the app remains unaffected; there is no entitlement to permanent availability of online services, future iOS/hardware compatibility, or unlimited future updates. Where reasonably possible, purchasers will be notified with advance notice before any online service is discontinued. The displayed prices (€9.99/year · €19.99 one-time) are introductory prices; regular prices (€12.99/year · €29.99 one-time) apply after the Early Bird phase ends.

Your ratings as a 3D terrain
Pure Eye Candy
Your matrix in 3D
Nobody needs it, but it looks cool.
Tap the cube in the matrix corner — and your 2D matrix transforms into a colorful 3D wireframe
terrain. High ratings become blue peaks, low ones red valleys. The camera tilts from top-down into
perspective, the terrain rises, and small summit crosses mark the strongest plateaus.
Transformation, not crossfade
The 2D dots grow directly into the terrain — the mesh blooms outward from your strongest ratings.
Altitude = rating
Red → yellow → green → cyan → blue. Color follows height, so you read the lens quality as topography at a glance.
Spin it around
One-finger drag rotates the terrain, pinch to zoom. Tap a point and the HUD shows focal length, aperture, and rating.

Every lens is context-dependent
A 50mm f/1.4 performs differently for portrait than for landscape. LensApp Pro separates ratings by use case.

Where do the ratings come from?
You enter your own observations from photos and tests. LensApp organises and compares those entries; it does not measure photos automatically. With Pro, LensCode also lets you import other people’s ratings. Treat them as a reference: cameras, subjects and personal expectations can differ.
