How much does Saily make per month?

Based on our ML-calibrated revenue forecast, Saily earns approximately $5.0K/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.

With estimated build cost $80K and monthly revenue $5.0K, Saily looks break-even-grade — payback period sits around 1.3 years. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

How many users does Saily have?

Estimated audience: ~14.5M lifetime downloads, ~2.1M monthly active users, and ~430K 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 Saily built with?

Our heuristic places Saily on the Native Android (Kotlin) stack (High confidence, 80%). Signals: app bundle size, category context, store-description markers, release-date era. We don't disassemble binaries. Alternative possibilities: Flutter.

Is Saily still actively maintained?

Maintenance status: Active (5% abandonment risk). Last shipped version was 8 days ago. The risk score combines time-since-last-update with Editor's Choice / curated featuring + user-base maturity adjustments.

How much would Saily sell for?

Estimated acquisition value: $75K (marketplace range $50K – $100K). Calculated as 16× 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 Saily last updated?

Saily last shipped a new version on 2026-10-27 — less than a month ago. This is the date Apple / Google last accepted a new build, not a content-only push.
