How much does Index make per month?

Based on our ML-calibrated revenue forecast, Index earns approximately $4.7K/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 $160K and monthly revenue $4.7K, Index looks break-even-grade — payback period sits around 2.8 years. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

How many users does Index have?

Estimated audience: ~19K lifetime downloads, ~3K monthly active users, and ~1K 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.

Browse the full Business category catalog to find similar apps with revenue, build cost, audience and tech stack data. Each /p/{slug} page also shows a Compare side-by-side widget with three peer apps from the same niche.

What is Index built with?

Our heuristic places Index on the Native iOS (SwiftUI) stack (Medium confidence, 60%). Signals: app bundle size, category context, store-description markers, release-date era. We don't disassemble binaries. Alternative possibilities: React Native, Flutter.

Is Index still actively maintained?

Maintenance status: Active (15% abandonment risk). Last shipped version was 3 days ago. The risk score combines time-since-last-update with Editor's Choice / curated featuring + user-base maturity adjustments.

How much would Index sell for?

Estimated acquisition value: $75K (marketplace range $50K – $100K). Calculated as 17× 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 Index last updated?

Index last shipped a new version on 2026-09-24 — less than a month ago. This is the date Apple / Google last accepted a new build, not a content-only push.

Index is published by Pinger, Inc. on the Apple App Store. See the full publisher portfolio (other apps by the same developer) via the More by developer block on the product page above.

💰 Revenue: Modest — $1K - $11K/mo · INDIE tier · medium confidence, trajectory unclear.
⭐ Quality: 3.92★ across 377 reviews — weak — significant quality concerns.
📍 Market: Not yet charting in any of the 9 monitored markets.
📈 Growth: dev shipping weekly.
⚠️ Risk: High — scam/fraud mentions detected, rating drift -2.04 ★ (recent 50 vs lifetime).

🎯 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 = $56K-$103K. Portfolio play ($96K/mo combined) commands premium. Discount applied for operational risk..
