ChemTracker predicts which aircraft overhead are leaving visible trails — in real-time. Using live ADS-B flight data, atmospheric conditions from 8 pressure levels, and the Schmidt-Appleman criterion, we analyze every aircraft within 250km of your location. Features: → Real-time flight map with contrail scoring → Sky Scanner: point at a trail, identify the aircraft → Golden hour alerts when visibility peaks → Evidence packs & field reports Free 14-day trial. No credit card. Worldwide.
Hey PH! I'm Remy, founder of ChemTracker.
Whether you believe in chemtrails or not — millions of people look up and wonder what those trails are. I built ChemTracker to give them real data instead of speculation.
The engine uses the Schmidt-Appleman criterion (the same physics meteorologists use) combined with Monte Carlo simulations to predict contrail formation for every aircraft overhead. We recently added a Sky Scanner — point your phone at a trail and it identifies which plane left it.
Would love your feedback. What features would you want to see next?
