Coming soon for iPhone

Stop converting. Start feeling Celsius.

Aha! trains the quick gut sense Americans need abroad: 21°C means t-shirt, 10°C means a jacket, and 35°C means hide from the sun.

Pip, the Aha guide
Pip helps the number click. Short practice moments turn Celsius from math into instinct.

Pip says: build the feel before the numbers disappear.

Google converts. Aha teaches.

Converters answer one number at a time. Aha! builds pattern recognition so the forecast, oven, pool, and thermometer stop feeling like a translation exercise.

1

Practice real moments

Weather, clothes, heat, cold, and travel scenarios instead of sterile conversion drills.

2

Fade the hints

Start with guidance, then gradually remove the crutches until Celsius feels normal.

3

Expand from Celsius

Temperature is just the beginning. More courses are coming soon, including distance, speed, weights, and other everyday units.

Pip waving

Pip keeps it light.

Metric confusion is annoying, not a moral failure. Aha! stays playful: quick prompts, friendly feedback, and enough repetition for the number to finally feel obvious.
