📝 About this app
Doesn't support iPads.
Developed in collaboration with Glyn Evans [the founder of iPhoneography], Provoke Camera was inspired by Japanese photographers of the late 1960’s like Daido Moriyama, Takuma Nakahira and Yutaka Takanashi.
Simple, elegant and easy to use, Provoke Camera does just one thing, produce black and white images with that gritty, grainy, blurry look reminiscent of the “Provoke” era of photography, and in two great formats; square format 126 and 35mm format 135.… View full description on the official store →

★☆☆☆☆ Provoke No Longer Working Properly
Provoke no longer saves JPEG images to my Photos (Camera Roll) since the iPhone iOS 16 Update. Now it only saves HEIC images. Previously it saved JPEG. This was a 5-Star app… now down to 1-Star. Sure would be nice if this glitch, or wha…
★☆☆☆☆ Can be so great, but is often rubbish
It simply doesn’t work all the time. It’s so incredibly frustrating. I often delete and reinstall, but even that doesn’t always get it working. What I mean when I say “working” is that it seems to be taking a photo, but it actually does not…

This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.

About this analysis
Why low confidence: only 5 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Provoke Camera is a early-stage iOS app in the photo & video space with weak public traction — only 5 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.
