## What is CoinTool?

CoinTool is a sentiment and cycle dashboard for the crypto market. The CoinTool Sentiment Score answers a single question: where is the market right now, and how does it feel?

Deterministic. Transparent. Replicable. No AI.

THE COINTOOL SENTIMENT SCORE
A 0–100 composite of five public market indicators, weighted and disclosed:
- Fear & Greed Index 
- MVRV Z-Score
- Multi-Exchange Funding Rate 
- Market Breadth (Top 20 above 50d MA) 
- Altcoin Season Index 

The full methodology is free for every user.

AUDIT EVERY NUMBER
Tap the score and see the complete calculation: raw values, normalization, weights, contributions — with timestamps for every data source. If a source is down, you see exactly how weights redistribute. 

THE SCORE ACROSS MARKET CYCLES
See how the score behaved against BTC price back to 2019 — recomputed on your device through the exact same formula as today's live score. Descriptive market data, not a performance claim.

SENTIMENT DASHBOARD
The default tab. Hero CoinTool Sentiment Score plus 10 tiles covering Fear & Greed, BTC Dominance, TOTAL/TOTAL2/TOTAL3, Stablecoin Supply, Altcoin Season, Funding, MVRV, Pi Cycle, Halving Countdown, and the Market Story Narrator — a short data-driven readout that summarises today in plain English.

ON-CHAIN VALUATION
MVRV Z-Score, Puell Multiple, and NUPL with 5-zone threshold bands and full historical context. See where the cycle sits, not just where price sits.

MULTI-EXCHANGE FUNDING & OPEN INTEREST
Aggregated perpetual funding rates and open interest from Binance, Bybit, and Deribit. Cross-venue view, no single-venue bias.

MARKET STRUCTURE
- Correlation Matrix (20×20)
- Market Breadth analytics
- Bitcoin Network Health: hashrate, difficulty, mempool depth, mining-pool distribution
- Pi Cycle Top Indicator
- Bitcoin Rainbow Chart, refit on 4,742 daily closes (R² 0.91)

NEWS & MARKET CONTEXT
Aggregated headlines from 8 RSS sources. Today's Bitcoin Moment / "On This Day". Halving Countdown. TOTAL, TOTAL2, and TOTAL3 market-cap aggregates.

WATCHLIST & ALERTS
Build a watchlist, observe live prices, and configure edge-triggered alerts for price, volume, and market-cap moves. Edge-triggered means one notification per cross — not a stream of repeats.

PROGRAMMABLE MARKET CONDITIONS
Combine up to three conditions into one rule across 14 metrics — from any coin's price to on-chain valuation and the Rainbow zone. Rules are edge-triggered with re-arm hysteresis: one notification per event, not spam. Fixed thresholds you define yourself — no AI, no fitting, fully inspectable.

DAILY SENTIMENT BRIEFING (PRO)
Optional local notification each morning with the current CoinTool Sentiment Score, day-over-day delta, and the active zone. Local-only — no push server is involved.

WIDGETS & LIVE ACTIVITIES
Eleven widgets across Home Screen, Lock Screen, and StandBy:
- CoinTool Score Circle (Lock Screen)
- Halving Countdown (Lock Screen Rectangular)
- On-Chain Snapshot (Lock Screen Inline)
- Network Health (Lock Screen)
- Watchlist (Lock Screen Rectangular)
- Plus Home Screen tiles for Fear & Greed, Rainbow zone, Funding, Network Health, and watchlist coins
- Live Activities and Dynamic Island for live BTC and Score readouts

PRIVACY & TRUST
- No accounts. No email. No login.
- No ads. No tracking. No analytics SDKs.
- No backend. No proxy.
- The app talks directly to public APIs (Binance, Coinbase, Kraken, mempool.space, BGeometrics, alternative.me, DefiLlama). All caching is on device.

PRO
Pro unlocks deeper detail-charts with longer periods, the full 20×20 Correlation Matrix, Live Activities, the Daily Sentiment Briefing, all 11 widgets, and unlimited alerts.

### 4.2.4 — 2026-08-25

- Composite Rules are now visible right on the Alerts screen — rule count and triggered state at a glance, even before you create a simple alert.
- Rule Builder: type a threshold directly instead of dragging the slider to the exact value. The slider stays for quick adjustments.

### 4.2.3 — 2026-08-24

Minor improvements and refinements.

### 4.2.2 — 2026-08-13

Composite Rules (Pro): combine up to 3 conditions into one rule — "Fear & Greed below 25 AND MVRV below 1.0 AND SOL below $150" — and get one notification when all of them hold. 14 metrics to pick from: any coin's price, 24h volume or market cap, CoinTool Score, Fear & Greed, MVRV Z-Score, BTC funding rate, BTC dominance, Altcoin Season Index, Rainbow zone, Pi Cycle distance, Puell Multiple and NUPL. Deterministic and transparent — you define the thresholds, CoinTool checks them. Free users see a preview with example rules.

Also in this update:
• Score share cards redesigned — and they now save straight to Photos.
• VoiceOver support across all dashboard tiles, improved light-mode contrast, full Reduce Motion support.
