📝 About this app
There used to be an entire industry based on red lights, that would have nothing (or very little) to do with scarcely dressed women - they called themselves photographers.
If you remember these times you probably call at least one of the mechanical wonders your own, which are today known as analog cameras and the best of them didn't have something called "in-camera metering" on the feature list.… View full description on the official store →

About this analysis
Why low confidence: only 19 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Photometer is a small / niche iOS app in the photo & video space with weak public traction — only 19 ratings, no founder-verified MRR, and not ranked in any monitored grossing chart. The app appears to be monetised, but public signals are too sparse for a precise revenue estimate.
Bottom line: treat all revenue, audience and acquisition-value numbers on this page as directional only — not founder-verified facts.
