smoggyapp

Citizen science platform for observing airplane contrails and their correlation with weather changes.

📡

How it works

1️⃣ Radar shows real aircraft near you
2️⃣ Tap the camera → photograph a trail
3️⃣ AI analyses the traces
4️⃣ Submit, take a 2nd photo to check spread

🌍

Your data matters

Your observations help researchers understand the relationship between trails, clouds, and weather. No photos stored — only anonymous data.

⚠ DELETE MY DATA

This permanently erases:

This cannot be undone. Observations already merged into an anonymised research dataset can no longer be linked to you, and cannot be removed from it.

‹DATA
🌐 See the world's sky

Turn this on to add your own observations to the shared world map — everyone can already see it, this just adds yours.

Never linked to your name or your account. Every observation you publish gets a small, fixed, private shift before anyone sees it — enough that repeated posts from the same spot can't be pieced together to work out where you shoot from.

You can turn this off anytime — just one tap.

Not now

🌐 Turning off sharing

Your future observations won't be added to the shared map anymore — you'll still see everyone else's.

Under GDPR you can withdraw consent at any time — this is exactly that.
