The Sea Level

See the world as it would look if all the ice melted.

Sea Level – If All Ice Melts turns your GPS location into a live picture of climate change. Track your real elevation in meters and feet, and find out whether the place you're standing would survive a 70-meter (230-foot) sea level rise — the amount locked in by Earth's remaining land ice.

Live elevation Get your current altitude in real time from GPS with online elevation data to back it up, updating as you move. Meters and feet are always shown side by side.

The 70m threshold A warning pops up the moment you're at or below the level the oceans would reach if every glacier and ice sheet melted. No guesswork — it's tied to your actual position.

Simulate Melt Watch the water climb to the 70m mark and see exactly what your location would look like: underwater, or 54 meters above the new shoreline. A few seconds is all it takes.

Background alerts Turn on system notifications for near-instant warnings when you're in a below-70m area — even when the app is closed or your phone is in your pocket. 2-hour tracking sessions keep it battery-friendly.

Clear at a glance A simple visual gauge tracks your elevation against the rising water, so you always know where you stand — with light and dark themes for reading comfort.

Sea Level is a tool for awareness and conversation. It makes an abstract number — 70 meters of sea level rise — feel personal. Underwater or not, the answer is one tap away.
