- 💰 Revenue: Modest — $721 - $4508/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.2★ across 15 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 698d ago — possibly dormant.
- ⚠️ Risk: High — 3.1% refund mentions, dormant (698d 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 = $21K-$39K. Portfolio play ($8K/mo combined) commands premium. Discount applied for operational risk..

About this analysis
Why low confidence: only 15 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
📌 Final verdict — read this before you trust the numbers above
Skoliometer is a small / niche iOS app in the education space with weak public traction — only 15 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.
