- 💰 Revenue: Marginal — $351 - $2196/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.35★ across 26 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 2191d ago — possibly dormant.
- ⚠️ Risk: Moderate — dormant (2191d since update).
🎯 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 = $15K-$28K. Portfolio play ($25K/mo combined) commands premium.

★★★★★ Fantastic and it just keeps getting better

★☆☆☆☆ Honestly it deserves 4 stars BUT!!!
I paid for pro and can't access the favorites I think it's kinda messed up to sell a feature and then not have it work. I love the app it's amazing but it needs an update and as others have said ability to input user formulas…

About this analysis
Why low confidence: only 26 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Math Ref is a small / niche iOS app in the news space with weak public traction — only 26 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.
