Features & Capabilities

Starfit is a health and fitness extension that tracks comprehensive body composition, including BMI, body fat percentage, body water, bone mass, visceral fat, basal metabolic rate, body age, and muscle mass. It also features body girth measurements and a baby/pet weight mode, plus cloud-based analytics that generate clear charts and reports for healthy living.

HealthKit integration lets Starfit share weight data with Apple Health after user consent; prompts appear on first use, and privacy controls let you modify permissions later. In guest/experience modes, data sharing is disabled to protect your privacy.

User Reviews

Starfit offers a broad set of metrics and an easy, multi-user experience that motivates tracking beyond weight. However, recurring issues with metric accuracy, chart data presentation, UI readability in dark mode, and connectivity/reliability undermine reliability. Users want more accurate body composition readings, correct chart calculations, smoother setup, and better integration with Apple Health. Overall, it shows promise for depth and motivation but needs substantial fixes to data accuracy and stability.

Pros

Wide range of body metrics (BMI, body fat, bone density, water, protein, muscle, etc.)
Easy to use with a simple scale-to-app workflow and automatic data syncing
Multi-user sharing allowing multiple household members to track their metrics
Motivational and helpful for weight management by showing progress across multiple metrics
Strong overall tracking of multiple metrics for comprehensive health insights

Cons

Inaccurate or misleading body composition readings and BMI guidance (recommendations/labels)
Chart and data display issues, including not averaging over periods and mismatched timeframes
UI/readability problems in dark mode and small font sizes
Connectivity and reliability problems (Bluetooth syncing, device not connecting, app crashes when using charts)
Cumbersome setup/onboarding and unit-switching difficulties

Recent reviews

After measuring weight a random popup appears with more information about the accuracy blah blah. It has a slider icon on the top which on the UX design point of view is supposed to allow sliding down the popup to dismiss it, doesn’t work. No X on the top corner either to dismiss it. How to dismiss it? Click the top part of the app where no popup exists, I forget every time because that’s extremely counter intuitive and the slider icon doesn’t work. I bet the dev will say it’s for aesthetics haha. Add that to the fact that it’s the same annoying popup I have to look at every morning, no way to tell it to go away forever.
