Industry 16 / Sports & fitness
Fitness products are retention businesses. Habit mechanics and honest data matter more than feature count.
Start a project →Where it usually breaks
01
Retention
Most users lapse within weeks. Streaks, reminders and social pressure move the number.
02
Wearable data
Device APIs disagree, sync late and report the same activity differently.
03
Background tracking
Continuous tracking has to work without destroying battery life.
04
Trust in numbers
Users abandon a product the moment its data contradicts their own sense of effort.

How we approach it
We instrument the retention curve first and design against the week where users drop off. Wearable data gets reconciled through one normalisation layer so the product shows a single believable number.
