🌍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
Why low confidence: only 79 ratings · no founder-verified revenue (model estimate only) · revenue figure is directional only.
❓ Frequently Asked Questions
8 answers · auto-generated from this app's public dataHow much does LingVo make per month?▴
Based on our ML-calibrated revenue forecast, LingVo earns approximately $86/mo. This is a US-storefront-equivalent estimate; global revenue can be several times larger for internationally-distributed apps. See the methodology page for the full formula and confidence bands.
Is LingVo profitable?▴
