Nothing inside you works alone.

Sleep affects your energy. Movement affects your mind. Stress can tighten your body and slow your recovery. Food, training, rest, and focus all shape how you feel and perform.

arc LockIn brings them together.

WORKOUT PLANNER AND GYM ROUTINES
Follow guided strength workouts for your goals and schedule. Build a custom gym routine. Track completed exercises. And work through progressive challenges and structured 40-day programs.

STRETCHING, MOBILITY, AND POSTURE
Use guided Bend & Stretch routines for tight muscles, desk stiffness, flexibility, mobility, posture, and everyday movement. Choose short sessions that fit the time you have.

NUTRITION AND CALORIE TRACKING
Search foods, scan barcodes, or use smart food scanning. Check serving sizes, calories, protein, carbohydrates, fat, and other nutrients. Log meals, water, weight, and body measurements. Then follow nutrition and diet challenges built around goals such as weight loss, muscle gain, high-protein eating, low-carb eating, Mediterranean meals, or balanced everyday nutrition.

SLEEP, RECOVERY, AND SMART ALARMS
Track available sleep and recovery signals in the same place as your activity. Review sleep duration, efficiency, timing, consistency, Deep and REM stages, HRV, resting heart rate, and more when supported by your connected data. Create a smart alarm with optional wake-up challenges and reminders for a more intentional routine.

FOCUS FLOW AND BRAIN EXERCISES
Start a Flow session for deep work, studying, recovery, a quick nap or a walk. Choose a soundscape and session length. Use short breathing, visual
attention and memory exercises when you want to settle into one task.

REMINDERS AND HOME-SCREEN WIDGETS
Keep the goal you chose where you can see it. Save quote cards, create personal stamps, add home-screen widgets, and schedule reminders that bring your next action back at the right time.

CONNECT YOUR HEALTH DATA
Sync supported health and fitness data through Health Connect. Available insights depend on the records your connected apps and wearable devices provide and the permissions you grant.

OPTIONAL PRIME AND LIFE PLANS
Optional subscriptions unlock more tools. Prime expands Flow, brain exercises, widgets, reminders, smart alarms, and stamp creation. Life adds the Health Performance Lab, ARC Age, advanced health reports, nutrition tools, Health Connect sync, and 40-day programs.
