A DISCIPLINED SECOND OPINION—WITH A RECEIPT ChartSnap turns a photo or screenshot of a trading chart into structured, educational decision support. Bring a readable chart, choose the market, and get a clear bullish lean, bearish lean, no-trade zone, or request for a better image. The result is designed to help you challenge a decision—not outsource it. UNDERSTAND THE EVIDENCE ChartSnap evaluates six visible technical factors: trend structure, support and resistance, candlestick or chart patterns, momentum, volume, and chart context. Its Confluence score summarizes how strongly those visible factors align. It is evidence strength, not win odds. MAKE RISK VISIBLE For directional reads, ChartSnap puts the proposed entry, invalidation level, targets, and measured reward-to-risk geometry together in one decision receipt. The app clearly labels whether the measured geometry meets its 1.5:1 quality bar. When the evidence is mixed, WAIT is a useful result—not a failure. KEEP AN HONEST JOURNAL Save each readable result automatically, then mark what happened later: Hit TP1, Hit TP2, Stopped Out, or Didn’t Take. Your chart, evidence, and outcome stay connected so hindsight does not rewrite the original decision. LEARN ONLY WHEN THE SAMPLE IS USEFUL Personal Insights summarize the outcomes you mark on this device. ChartSnap withholds headline and segment rates until minimum sample sizes are reached, so one or two results are never presented as meaningful performance evidence. WHAT EACH READABLE RESULT INCLUDES • Bullish lean, bearish lean, or no-trade zone with text and symbols • Confluence/evidence-strength score—not a calibrated win probability • Entry, invalidation, two targets, and measured reward-to-risk when directional • Six-factor evidence breakdown with supporting notes • Annotated chart and concise shareable decision receipt • Automatic entry in your private on-device Journal PRIVATE AND STRAIGHTFORWARD No account, API keys, contacts, or location access. Your first three analyses are free. Chart images are sent to ChartSnap’s analysis service only to produce the requested read; saved Journal records remain on your device. SUBSCRIPTION After three free analyses, ChartSnap offers auto-renewing weekly and yearly subscriptions for continued chart analysis, Journal continuity, outcome review, and Personal Insights, subject to the current fair-use limit. Payment is charged to your Apple ID at confirmation. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID settings. Terms of Use: https://chartsnap.app/terms Privacy Policy: https://chartsnap.app/privacy IMPORTANT—PLEASE READ ChartSnap provides model-assisted technical chart analysis for educational decision support only. It is not financial advice, a recommendation, or a solicitation to buy or sell anything. The Confluence score is not a calibrated chance of profit. No read predicts the future. Trading involves substantial risk of loss. Past results do not predict future performance. Always do your own research.

Verdict
The clearest difference is ads: ChartSnap at none against Nexus's shown. Nexus's advantage is iOS requirement (15.1 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.
