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 0โ100 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 โ 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 โ 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 โ 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 (20ร20) - 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 (Rยฒ 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 โ not a stream of repeats. PROGRAMMABLE MARKET CONDITIONS Combine up to three conditions into one rule across 14 metrics โ 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 โ no AI, no fitting, fully inspectable.

Verdict
The clearest difference is price: CoinTool at Free against GoldBug's $3.99. CoinTool also leads on iOS requirement (17.0 vs 26.0). GoldBug's advantage is in-app purchases (none vs 3). On review sentiment, update cadence, ads and monetization model there is nothing between them.
