ecoTRX Pro Personalized MPG

IMPORTANT: ecoTRX Pro is an enhanced version of our free ecoTRX App (see chart in screenshots for detailed comparison). ecoTRX Pro is now free for a limited time.

The ecoTRX™ Pro App is designed to help you achieve and report more personalized fuel economy levels. ecoTRX combines your engine data (available on 1996 and later OBD-II equipped vehicles) with GPS location data, NOAA weather data, and EPA vehicle data to provide personalized and context-aware MPG information during and after your trip. For example, ecoTRX Pro senses when you are driving in city conditions and can report both your MPG and average miles between stops. When ecoTRX Pro senses you are in highway conditions, it reports MPG and average highway speed,. ecoTRX Pro can also report total trip fuel price in both modes. ecoTRX Pro harnesses the Android Text To Speech (TTS) engine to deliver this personalized MPG information in an audio format to help keep your eyes on the road. ecoTRX Pro also lets you share and compare fuel economy information with other users of the EPA My MPG site. Reports delivered through the ecoTRX Pro app can provide more detailed fuel economy metrics that may be used in the future to help other consumers find MPG ratings which more closely match their conditions (i.e. similar A/C usage, mix, highway speeds, city miles per stop, and flat vs. hilly terrain).
