Ark Core.
Workout and nutrition apps built to work together—helping you lift stronger, eat smarter, and recover faster without the guesswork.
Two specialized apps. One shared brain.
Ark Fit
Your smart gym partner. Track your lifts effortlessly, check your lifting form with your phone camera, and get workouts that automatically adjust to how your body feels.
Ark Nutrition
Food tracking without the headache. Snap a photo of your plate to log meals in seconds, track key vitamins alongside calories, and build instant grocery lists.
Your apps finally talk to each other.
Most workout apps have no idea what you ate, and most diet apps don't care how hard you lifted. Ark connects both in the background so your food goals and workout plans adjust to each other automatically.
- Works Instantly, Even Offline:
Everything saves right on your phone first—no loading spinners or lost workouts when gym Wi-Fi drops.
- Meals & Workouts Adjust Together:
What you eat and how you train stay connected automatically, so you never have to copy numbers between apps.
- Private & Always Backed Up:
Your personal health data stays locked down and syncs quietly across your devices.
Two Apps. One Brain.
Most fitness apps have no idea what you ate. Most diet apps don't care how hard you lifted. Ark connects both so your meals and workouts actually work together as a team.
Crushed leg day? Ark Nutrition automatically bumps up your dinner protein target so your legs don't feel like bricks tomorrow.
Ate a light lunch? Ark Fit gives you a heads-up before your 5 PM workout so you pace your sets and don't burn out early.
Taking a rest day? Ark Fit dials back workout intensity while Ark Nutrition adjusts your daily calories automatically.
