What Is Starfit?
Starfit is a health and fitness app that helps people track their body and stay active at home. The app brings fitness tools directly to your smartphone and removes the need for a gym.
Two main versions exist. One version connects with a smart scale and tracks your body data. The other version shows you workout videos led by professional trainers. Both versions serve different needs but share the same goal, to help you stay healthy.
Version 1: Body Tracking App (by RUNSTAR FL INC.)
This version works with a smart weighing scale. You step on the scale, and the app reads your body data automatically. It launched on December 30, 2021, and supports many languages including English, Chinese, Japanese, and Korean.
The app measures and tracks the following:
Body fat percentage: shows how much fat your body carries
Muscle mass: tracks your strength gains over time
Body water percentage: monitors your hydration levels
Bone mass: keeps a record of your bone health
BMI (Body Mass Index): tells you if your weight is healthy
Basal metabolic rate: calculates how many calories you burn at rest
Body age: compares your body health to your real age
The app also includes a Baby & Pet Weight Mode. You hold your baby while standing on the scale, and the app calculates the baby’s weight separately. This feature helps new parents track their baby’s growth easily.
The app stores all your data in the cloud. You can view your health history on any device. It also connects with Apple Health on iPhone and shares your weight, BMI, and body fat data with permission.
The app supports multiple family members under one account. Each person gets their own profile. This makes the smart scale useful for the whole family.
Version 2: Home Workout App (by FITSTARS FZCO)
This version focuses entirely on exercise. It launched worldwide in 2025 after a successful beta period. You do not need any equipment, just follow along with the video trainers on your phone.
The app offers:
Over 200 workout videos across more than 20 training programs
Programs for weight loss, yoga, stretching, abs, glutes, and meditation
Professional trainers who are champions and masters of sport in their fields
Offline access: download workouts and use them without internet
A healthy recipe section for better nutrition
Seasonal events with 30 free workouts for 30 days
Progress tracking with badges and workout streaks
Blog articles that teach you about fitness, nutrition, and recovery
The app syncs your progress across your phone and computer. It also filters workouts by time of day (morning, afternoon, or evening), fitness level, and body focus area.
Privacy for Beginners
Many people feel embarrassed exercising in front of others. They worry about looking foolish or being judged. With Starfit, you exercise alone at home. No one watches you. No one comments on your form. You can pause, rewind, or stop anytime. This privacy helps beginners build confidence.
User-Friendly Interface
The Starfit app has an intuitive design. Anyone can use it without training. You can filter workouts by time of day: morning, afternoon, or evening — as well as by fitness level and focus area. The main page shows popular programs in a carousel format.
How Starfit Educates You About Body Fitness
The app includes blog articles covering:
Fitness tips and techniques
Health and wellness
Nutrition advice
Recovery and motivation
You learn why certain exercises work and how nutrition affects your body. This knowledge helps you make better decisions even outside the app.
Language Support
The Starfit app supports 11 different languages:
English
Chinese (Simplified and Traditional)
Japanese
Korean
German
French
Spanish
Italian
Russian
Portuguese
This makes the app accessible to users across many countries.
App Size and Storage Requirements
The body tracking version takes up approximately 301 MB of storage space on your phone. The workout version requires about 283 MB. You will also need additional free space for saving offline workouts and storing measurement history.
Customer Support Availability
The developer of Version 1 (RUNSTAR) provides email support at service@runstar.com for technical issues. Response time typically ranges from 24 to 48 hours. The app also includes a built-in FAQ section that answers common user questions.
Offline Access
You can save workouts directly to your phone. This means you do not need an internet connection to exercise. You can work out anywhere; in a park, hotel room, or basement. The workouts stay on your phone until you delete them.
Starfit App Recipe Section
The app includes a section with healthy recipes. These recipes help you eat better while you exercise. Good nutrition combined with exercise gives better results. The recipe section was a long-awaited feature that users had requested for a long time.
How It Works
1. Syncs with your plan: The app already knows your weight, height, target calories, and protein from your profile. The Recipe section uses that data.
2. Filters recipes: It shows only recipes that fit your calories and macros for that meal. For example, if lunch = 500 cal, 30g protein, you see only meals in that range.
3. Step-by-step cooking: Tap a recipe, you get an ingredients list and a step-by-step cooking timer. The app walks you through each step like a coach.
4. Auto logs: When you mark “Cooked it”, the calories and macros go straight to your daily food diary. No manual entry needed.
Types of Recipes You Get
| Goal | Recipe Types |
| Weight Loss | Low-calorie, high-protein: Grilled chicken salad, Oats chilla, Lentil soup, Greek yogurt bowls |
| Muscle Gain | High-calorie, high-protein: Chicken + rice, Paneer bhurji + roti, Protein smoothies, Egg bhurji |
| Vegetarian / Non-Vegetarian | You set the filter. The app shows only veg or non-veg based on your choice. |
| Time-Based | 10-minute recipes, 20-minute recipes, meal-prep for 3 days |
Seasonal Events
The Starfit app runs special monthly programs called seasonal events. These events give you access to 30 workouts for 30 days completely free. You can explore all the app content through these events, which helps you decide if you want to subscribe.

Our Editorial Take
Starfit offers the best of both worlds in one place. Many fitness apps only track your data or only provide workouts, but Starfit connects your smart scale measurements directly to your exercise programs.
This means you can see your body fat percentage drop right alongside your workout progress, which keeps you motivated. The offline workout feature also gives you the freedom to exercise anywhere without needing an internet connection. For someone who wants a complete fitness solution without buying multiple apps or subscriptions, Starfit delivers real value at a reasonable price.
Which Version Is Right for You?
It depends on your needs:
Choose the body tracking version if you want to monitor your health metrics and own (or plan to buy) a smart scale.
Choose the home workout version if you want to exercise at home with video guidance and no equipment required.
