Here is a tiny device that helps you make better sense of car issues. FIXD works with most vehicles sold in the U.S. after 1996 and translates your check engine light into understandable terms. It gives you a better idea on the severity of each issue and what could happen if you keep driving your car before fixing it.
FIXD is compatible with iOS and Android devices. It reminds you when to perform maintenance on your car. The product is shipping for under $40 at this time.
