Turn a chart screenshot into a clear, balanced study. Chart AI helps self-directed traders examine what a chart visibly supports—without promising profits or pretending a price prediction is certain. Upload one chart and receive a structured second opinion you can revisit on your device. EVERY CHART STUDY INCLUDES • Chart-quality and timeframe checks • Trend and market-structure observations • Approximate support and resistance zones • Bullish evidence and bearish evidence side by side • What observable move would change the current read • A practical risk and missing-information checklist BUILT TO HELP YOU THINK, NOT FOLLOW Chart AI does not connect to your broker and never tells you to buy or sell. It explains visible evidence, flags uncertainty, and separates a thesis from the conditions that would invalidate it. Use it to challenge your own read, prepare questions, and learn chart concepts over time. TRY THE FULL RESULT FIRST Open a complete sample study before uploading anything. Then use your included free analyses to study your own stock, crypto, or forex charts. PRIVATE BY DESIGN You choose every image. Metadata is removed and the chart is resized before secure upload. The cloud chart file is deleted immediately after the analysis request finishes. Written studies are stored only on your device. No brokerage login is required. CHART AI PRO Upgrade for unlimited chart analyses and an expanding on-device study history. Available plans and localized prices are shown in the app before purchase. Payment is charged to your Apple ID. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings. Chart AI provides educational chart studies only. It is not a broker, fiduciary, financial adviser, investment recommendation, or price-prediction service. Verify all information independently and make your own decisions. Privacy Policy: https://renaissanceapps.com/privacy-policy Terms of Use: https://renaissanceapps.com/terms-conditions

About

Snapper

Features
Read full description

Snapper is the iOS companion for the Snapper trading platform — a native SwiftUI app that lets you watch positions, place orders, attach stops, and respond to alerts from your phone, against the backend you configure and control. WHAT IT DOES • View live positions, orders, executions, and balances across multiple wallets and exchanges. • Place market and limit orders, attach stop-loss and take-profit brackets, and configure trailing stops — all with reduce-only safety on close-out flows. • Receive instant push notifications for fills, stop-loss triggers, system warnings, and alert routing rules you control per-device. • Manage alert preferences with per-(alert type, scope) overrides — quiet hours, mute timers, and minimum priority. • Switch between live and paper trading modes; the app surfaces the (paper) tag everywhere a wallet is referenced so the two modes are never confused. • Time-travel: replay historical bus state to inspect what your strategies saw at a given moment. WHO IT'S FOR Self-directed traders who run their own Snapper backend. The app is a thin client; it expects a Snapper-compatible API on the URL you configure. If you don't already run a Snapper backend, this app won't be useful to you on its own. PRIVACY Snapper is open source (MIT) and ships zero third-party SDKs — no analytics, no ad networks, no crash-reporting libraries. The app talks only to the backend you configured and to Apple Push Notification service (for alerts you opted into). Source code is at github.com/mateusz-klatt/snapper-ios. Privacy policy: snapper.ch/privacy-policy.html. REQUIREMENTS • A running Snapper backend (you provide the URL during sign-in). • iOS 26 or later. iPhone only. • Push notifications are optional; the app is fully usable without them. NOT FINANCIAL ADVICE Snapper is a trading interface, not a trading strategy. The app does not provide market analysis, trade recommendations, or financial advice. Markets carry risk; trade what you can afford to lose.
