About this app
Krisalya Energy goes beyond price comparators. Instead of showing you the cheapest station per liter, the app computes the TRUE TOTAL COST of every fill-up: fuel price + detour + time lost + vehicle wear. The result? The most cost-effective station is almost never the one you think. WHY IT'S DIFFERENT Driving 10 km out of your way to save 7 cents per liter? On a 50 L fill-up you save €3.50 on fuel... but you lose €4.80 in detour, time and wear. Net: −1.30 €. Krisalya shows you the real best option right away.
