Petrollo offers a free mobile app that uses a phone’s accelerometer, GPS, and engine‑load data to detect optimal coasting moments and prompts drivers with a visual cue to lift off the accelerator. The app calculates real‑time fuel and CO₂ savings and displays cumulative results in a dashboard, with an optional €1.99 in‑app purchase for a custom overlay image. All processing runs on‑device with optional encrypted cloud backup for trend analysis.

Problem
Many drivers maintain excessive throttle input when approaching stops, roundabouts, or traffic lights, resulting in unnecessary fuel consumption and elevated CO₂ emissions. The lack of real‑time feedback on optimal coasting moments makes it difficult for motorists to adjust their driving style efficiently.
Solution
Petrollo delivers a free mobile application that leverages the phone’s accelerometer, GPS, and engine‑load data to identify moments when coasting is advantageous. The app provides an on‑screen visual cue prompting the driver to lift off the accelerator, thereby harvesting kinetic energy and reducing fuel burn. It continuously calculates estimated fuel savings and CO₂ reduction, presenting the data in an easy‑to‑read dashboard that reinforces smoother driving habits. Users can personalize the interface by purchasing a custom image overlay for €1.99, which is displayed during the coasting prompts. All telemetry is processed locally on the device, with optional cloud sync for historical trend analysis while maintaining GDPR‑compliant data handling.
Target Audience
The primary users are private motorists—especially urban commuters—who seek to lower fuel expenses and environmental impact, as well as small fleet operators looking to improve driver efficiency.
