## What is Krisalya Energy?

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.

PREMIUM FEATURES

• Top 3 podium of the most cost-effective stations (gold, silver, bronze)
• Transparent math: price × volume + detour + time value + wear
• Around-me mode, address mode, route mode (2 km corridor)
• Real road distance computed for the top 3
• “Go” button that opens Maps, Waze, Google Maps, Coyote, TomTom, HERE WeGo or Mappy
• “I went there” confirmation that measures your actual savings
• Cumulative savings shown in your profile (€ + minutes saved)
• Multi-vehicle: one vehicle per use (personal, work, spouse)
• Adjustable fill-up volume (1/4, 1/2, 3/4, full, custom)
• Brand filter (TotalEnergies, BP, Esso, Carrefour, Leclerc...)
• Electric vehicle mode: chargers, connectors, power, customizable kWh rate
• Offline mode: the last station list remains available
