- 💰 Revenue: Modest — $891 - $5571/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.53★ across 19 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.

- ⚠️ Risk: High — bug mentions above category norm, rating drift -0.73 ★ (recent 50 vs lifetime), dormant (1684d since update).
🎯 For competitors: Vulnerable. Quality drift + slow updates create a clear opening for a fresh competitor with active dev cadence.
💵 For acquirers: Estimated asking range 12-22× monthly = $26K-$49K. Portfolio play ($13K/mo combined) commands premium. Discount applied for operational risk..

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.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.

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
Kopfschmerztagebuch Pro is a small / niche iOS app in the health & fitness 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.
