Tandem

An AI-powered walking habit app that adapts to your mood and health

The project is in continuation of the research presented in the Interactive- Ux map

How do you help someone prevent a condition they don’t even feel?

Diabetics begin lifestyle changes—but struggle to stay consistent without external support

Pre-diabetics live with unbalanced habits but since symptoms stay silent, effort stays minimal.

Through conversations with doctors, diabetics, pre-diabetics, and families (Sample size- 10, in-depth interviews), I uncovered two key problems:

Background

"After one year of maintaining lifestyle got bored and ditched it"

Demographic stats

Meanwhile, data reveals a larger crisis:

49.4%

Indian adults are physically inactive

Type 2 diabetes has a strong hereditary component, meaning family history significantly increases the risk of developing the condition

Pre-diabetic Indians don’t even know their status

42%

Digging deeper into using COM-B behaviour models, I learned:

Behavioural research insights

People need physical and emotional alignment to move

Most of all, the user wasn’t seeking discipline.
They were seeking ease and a sense of togetherness.

Habits are hard to break—but easier together

Flexible routines and human warmth beat rigid tracking

Tandem helps intergenerational pairs—like a father and daughter—build a habit of physical activity.
Moderated by AI, motivated by human connection.
