Analytics and monitoring decision
ChartsGPT
A single developer can reproduce the core screenshot→analysis workflow and a web-based assistant in about a week, but the full mobile product experience (native app, lock‑screen signals, App Store subscription polish and academy content) and any proprietary backend optimizations are not reproduced cheaply.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All ChartsGPT alternatives, with the arithmetic →
What a replacement has to do
- Upload or photograph a chart → detect symbol/timeframe → extract structure/key levels → run rule-based technical-analysis engine → generate human-readable trade setup and score
What it still won’t have
- Native iOS app UX and App Store distribution (lock‑screen live signals and push notifications)
- Polished, production mobile UI/animations and built-in Academy content
- App Store subscription handling and built-in referrals/ratings
- Any proprietary backend optimizations or internal models not documented on the App Store page
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a small web service (React frontend, Flask or FastAPI backend, Postgres) that accepts a chart photo upload, identifies the market symbol and timeframe (use an OCR/vision model or OpenAI Vision), runs a rule-based technical analysis engine (trend, support/resistance, simple pattern detection) to produce entry/stop/target and a quality score, and uses an LLM (OpenAI-compatible) to render human-readable explanation and an interactive Q&A assistant. Core features in scope: image upload, symbol/timeframe detection, TA rules engine, LLM explanation pipeline, basic watchlist with live quotes via a market-data API, user account & saved analyses. Out of scope: native iOS app, App Store subscription integration, advanced Academy lessons, push notifications. Include error handling, input validation, unit tests for analysis logic, and deployment scripts (Docker + small cloud instance).

- 2 cited sources+1
- Price verified on pricing page+3
- Evidence score61
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
