Take a picture of any price chart. ChartGrade reads what's on it - the trend, the levels price actually reacted to, the candlestick patterns it can trace - and tells you how clearly it saw each one. Then it gives you the call: buy, sell or hold, with a number for how sure it is and the reasoning underneath. WHAT YOU GET - A straight call, and a certainty score that isn't rounded up - The reasoning behind it, not just an arrow - Support and resistance, with how many times price actually reacted there - Chart patterns and indicators it can genuinely see, each with its own confidence - A look beyond your screenshot: the longer timeframe, and what analysts have published - A history of every reading, with what happened next WHAT IT READS Trend direction and structure. Support and resistance levels, with touch counts. Chart patterns - double top, double bottom, head and shoulders, ascending and descending triangles, rising and falling wedges, channels, cup and handle, ranges and consolidations. Moving averages, RSI, MACD, volume and Bollinger Bands, when they're on the chart and labelled. Timeframes from one minute to monthly. WORKS WITH THE APP YOU ALREADY USE Point the camera at your screen, or pick a screenshot from your library. If you can screenshot a price chart from your broker or charting app, ChartGrade can read it. Stocks, crypto, forex, indices and commodities all work the same way. It doesn't need to know which app the chart came from. It just reads the picture. IT LOOKS PAST THE CHART Your screenshot is one timeframe, and a one-day chart routinely looks bullish inside a six-month downtrend. One tap pulls the longer view and what analysts have published about the instrument. That part comes from the web rather than from your image, and the app says which is which. IT TELLS YOU WHEN IT CAN'T HELP Point it at something that isn't a price chart and it says so instead of guessing. A blurry photo gets a refusal, not an invented analysis. This matters more than it sounds: a tool that always has an answer is confidently wrong some of the time, and you've no way to tell which times. IT KEEPS A RECORD Mark how each reading played out - moved as read, moved against, still unclear. The history builds a track record instead of a folder of screenshots, and you can see which setups you read best. TECHNICAL ANALYSIS, WITHOUT THE MYSTICISM Chart patterns don't reliably predict prices, and any app telling you otherwise is selling something. ChartGrade describes what the present structure favours and attaches a confidence to it. That's a defensible claim. "This will go up" isn't. WHO IT'S FOR People who already look at charts and want a second read on one. Day traders and swing traders checking a setup. Anyone learning technical analysis who wants the reasoning spelled out rather than a signal to copy. WHAT IT ISN'T ChartGrade is an educational tool for reading charts. It's not a signal service, not a trading bot, not financial advice, and it can't predict prices. Trading carries a high risk of loss. Seek qualified professional advice before any financial decision. NO ACCOUNT No sign-up, no login, no email address. SUBSCRIPTION ChartGrade Unlimited is a subscription with weekly and six-month options. Prices show in your local currency before you buy, and you can cancel any time in your App Store settings.

One chart screenshot is all it takes. Chart Lens identifies the instrument, checks its price history and indicators, and sums up what the chart is showing right now. [ How it works ] 1. Pick a chart image from your photo library. 2. AI reads the instrument, market, and chart structure. 3. Your device fetches a year of price data and computes indicators. 4. The reading and the computed values are combined into one report. [ What the report covers ] Ā· Instrument and current signal Ā· A price & volume chart drawn from real market data Ā· Key price levels such as support and resistance Ā· Upside and downside scenarios with invalidation conditions [ The report screen ] Support and resistance lines are drawn over a price & volume chart built from real market data, alongside signal scores for trend, momentum, and participation, evidence statements, and response scenarios — all on one screen. When market data is verified, the signal and score are fixed by on-device rules, not by the AI. [ Indicators are computed on device ] 52-week high and low, period return, SMA 5/20/60, RSI 14, MACD, ATR 14, Bollinger Bands 20, and 20-bar average volume are calculated by the app itself, so no number is invented that isn't grounded in real data. [ Please read ] Chart Lens is a technical analysis reference tool, not investment advice. Scores shown are rule-based signal strength, not probabilities or expected returns. Past data and indicators do not guarantee future results. You are solely responsible for your own investment decisions and their outcomes. Available in English, Korean, and Japanese. [ Chart Lens Pro ] Every user gets 3 free chart analyses. Chart Lens Pro removes that limit - unlimited chart analyses, nothing else is gated. - Chart Lens Pro Yearly: US$22.99 per year, including a 3-day free trial - Chart Lens Pro Monthly: US$2.99 per month Prices vary by region and the exact amount is shown before you confirm the purchase.

You can manage or cancel your subscription in your Apple Account settings after purchase. Any unused portion of a free trial is forfeited when you buy a subscription.
