Brief summary: The goal of this study is to evaluate the effectiveness of financial incentives delivered in real-time at point of purchase, on low-income consumers' purchase of fruits and vegetables, fruits and vegetables consumption, diet quality, and weight/BMI. The study will test real-time incentives compared to a no-incentive control condition.

Detailed description: To address diet quality disparities in low-income families, policy makers and health experts recommend strategies such as financial incentives to promote consumption of fruits and vegetables. Real-time incentives for purchasing fruits and vegetables are promising strategies to improve families' diets and health.

The aims of the study are:

1. To test the effects of financial incentives, delivered in real-time at the point of purchase, on low-income consumer purchases of fruits and vegetables
2. To evaluate the impact of real-time financial incentives compared to a control condition on FV consumption among adults and their children ,shopping habits, home food environments, diet quality, and weight/BMI
3. To adapt mobile platform technology to provide regular feedback to participants to motivate use of the incentive program to increase purchases and consumption of fruits and vegetables
4. To evaluate participant satisfaction with real-time healthy food choice incentives technology in both SNAP participants and income-eligible non-SNAP participants
5. To assess the acceptability and ease of use of real-time healthy food choice incentives technology among retails supermarket managers and staff in low-income neighborhoods.
