  • 💰 Revenue: Marginal — $320 - $2005/mo · INDIE tier · medium confidence, trajectory unclear.
  • ⭐ Quality: 5.0★ across 6 reviews — weak — significant quality concerns.
  • 📍 Market: Not yet charting in any of the 9 monitored markets.
  • 📈 Growth: Insufficient signal to assess trajectory.
  • ⚠️ Risk: Low — no material risk signals detected.
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $14K-$25K. Portfolio play ($2K/mo combined) commands premium.

🌍Geographic ReachNot ranked
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
ZCAnalyzed by Zakhar Chumak · founder, bumetric·Full methodology·Low confidence

Why low confidence: only 6 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.

📌 Final verdict — read this before you trust the numbers above

MBOX Viewer is a early-stage iOS app in the business space with weak public traction — only 6 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.
