Brief summary: The purpose of this study is to evaluate the impact of personalized move goals in the Welltory mobile app on daily step count among adults from 30 to 65 years old. The study also aims to assess how personalized move goals impact workout quality and frequency.

Detailed description: The Welltory app sends users messages with move goals to help people move smarter. Adapted daily based on each user's historical data and overall wellbeing, Welltory's move goals gradually increase physical activity levels, motivating sedentary people to move more without demanding drastic lifestyle changes.

This randomized controlled study will assess if messages with personalized move goals in the Welltory mobile app help increase physical activity among adults.

Participants include individuals aged 30-65 who use iPhones, wear an Apple Watch, and lead sedentary lifestyles (their median daily step count does not exceed 6,000). Participants are selected among active Wellotry mobile app users who had previously not received any messages with move goals.

All participants are randomly assigned to 3 groups:

* Participants in group 1 receive daily messages with personalized move goals in the Welltory mobile app. Personalized move goals are computed based on each participant's historical physical activity data and their daily wellbeing.
* Participants in group 2 receive daily messages with a static move goal of 10,000 steps per day in the Welltory mobile app.
* Participants in group 3 use the Welltory mobile app but don't receive any messages with move goals.

For all participants, steps and workouts are automatically registered by their Apple Watch wearable devices and the Welltory mobile app. Additionally, participants regularly measure their body weight and manually record it in the Welltory mobile app.

This study's duration spans a total of 24 weeks for each participant.

Eligibility criteria: Inclusion Criteria:

* Using an iPhone smartphone
* Using an Apple Watch
* Willing to use the Welltory app every day for 6 months
