<scp>mMotiv8</scp>: A smartphone‐based contingency management intervention to promote smoking cessation

The team built a phone app called mMotiv8. Each morning the user blows into a tiny breath tester. The app reads the carbon-monoxide number to see if the person smoked.

If the sample shows no smoking, the app instantly loads five dollars onto a debit card. The study used a multiple-baseline design across adult smokers.

Abstinence jumped from four percent to eighty-nine percent while the rewards were in place. People said the app was easy and they kept using it every day.

Lindhiem et al. (2015) looked at twenty-five phone-app studies and found a small but steady boost when mobile tech is added to any behavior plan. mMotiv8 shows one way to get that boost with a clear reward.

Rutter et al. (1987) got kids to buckle up by giving tokens after practice and praise. The same token idea now works through a phone and a debit card for grown-ups trying to quit cigarettes.

Zohrabi et al. (2025) also used a therapist-guided phone app, but they taught self-care to children with autism. Both studies prove a BCBA can run an effective program without being in the same room.

You can deliver powerful contingency management without a clinic. Ship the client a breath tester and load money from your laptop. The photo proof and auto-payment handle honesty and timing for you. Try it with any adult who wants to quit smoking, vaping, or even sugary drinks.
