How much does Vocabulary.com make per month?

Based on our ML-calibrated revenue forecast, Vocabulary.com earns approximately $700K/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 Vocabulary.com profitable?

With estimated build cost $125K and monthly revenue $700K, Vocabulary.com looks highly profitable — pays back its build investment in under a month at the current run-rate. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

How many users does Vocabulary.com have?

Estimated audience: ~515K lifetime downloads, ~28K monthly active users, and ~5K daily active users. Derived from ratings count × category installs-per-rating × age decay. US-storefront-equivalent — global audience can be 5-10× larger for internationally-distributed apps.

What is Vocabulary.com built with?

Our heuristic places Vocabulary.com on the Native iOS (Swift / UIKit) stack (High confidence, 80%). Signals: app bundle size, category context, store-description markers, release-date era. We don't disassemble binaries. Alternative possibilities: Native iOS (SwiftUI).

Is Vocabulary.com still actively maintained?

Maintenance status: Likely abandoned (93% abandonment risk). Last shipped version was 5+ years ago. The risk score combines time-since-last-update with Editor's Choice / curated featuring + user-base maturity adjustments.

How much would Vocabulary.com sell for?

Estimated acquisition value: $12.5M (marketplace range $9.5M – $16.5M). Calculated as 18× monthly revenue using the standard multiple for the detected monetization model + adjustments for age, rating quality and category demand. Calibrated against 2024-2026 Flippa / Acquire.com / MicroAcquire closed-deal medians.

When was Vocabulary.com last updated?

Vocabulary.com last shipped a new version on 2021-09-22 — more than 5 year(s) ago. This is the date Apple / Google last accepted a new build, not a content-only push.
