MPG Stat

MPGStat is a subscription app. Try free for 1 month, then $1.99/month or $14.99/year. All features require a subscription. MPG Stat is the fuel economy tracker for people who actually care about the numbers. Built on Statistical Process Control (SPC) principles, MPG Stat doesn't just log your fillups — it helps you understand whether changes in your fuel economy are real signals or just noise. XmR charts show your individual values and moving range over time, giving you the same analytical tools used in engineering and quality control, applied to your daily drive. Track every fillup, spot trends, and know with confidence when something has actually changed — not just varied. Features: - XmR (Individual and Moving Range) control charts - Natural Process Limits to distinguish signal from noise - Fillup history with running stats - Clean, fast logging — just miles and gallons - A little whimsy for the road Perfect for engineers, hypermilers, data nerds, and anyone who has ever wondered whether that new air filter actually made a difference.
