About ChartLens
ChartLens is an educational iOS app that analyzes trading charts with AI and publishes its own verified win rate.
Why it exists
There is no shortage of tools that will read a chart and tell you what they see. What none of them do is tell you how often they have been right — and without that, an analysis is just a confident paragraph. The same tone comes back whether the read was excellent or nonsense, and nobody is counting.
ChartLens counts. Every analysis with a numeric stop and target is logged the moment it is produced, checked against exchange candles until it resolves, and published — including the ones that went wrong. That constraint shaped the whole product: it is why the app is allowed to say there is no setup, why it refuses to quote prices off an unreadable axis, and why an idea that broke before it was ever fillable scores zero instead of counting as a loss.
What it will not do
- Tell you what to buy or sell. It has no idea who you are.
- Connect to a broker or exchange account, or place a trade.
- Quote a price it read off an axis it could not make out.
- Manufacture a setup on a chart that does not contain one.
- Publish a win rate computed from a handful of outcomes.
Who builds it
ChartLens is built by a small team that trades the charts it writes about. Everything published here is checked against the app’s own scored record before it goes out.
It is a small independent product, not a fund, not a signals service and not an affiliate of any exchange. There is no revenue share with anyone whose product might appear in an analysis, and the only thing sold is the subscription.
How it is built
The app is iPhone-only. Analysis runs on a vision model behind our own server — the model can be swapped without an app update, and every analysis records which model and prompt version produced it, so a change in quality can be traced to the change that caused it.
There are no accounts. The app generates an anonymous identifier on device; there is no email, no password, and no profile. Chart images are deleted once an analysis resolves or after 30 days at the latest, and Settings has a one-tap delete that removes everything.
Corrections
If something on this site is wrong — a comparison, a figure, a claim about another product — tell us and it will be corrected, including when the correction is unflattering. That is the same standard the track record is held to; it would be strange to apply it to our own results and not to everything else.
