Arrow is the #1 workout and nutrition tracker built for changing your body. Log your lifts, meals, and weight in one app, get calorie and macro targets that adapt to your real results, and see whether training and diet are actually adding up, whether you're cutting, bulking, or just looking to maintain. TRAINING AND NUTRITION IN ONE LOOP Changing your body is one problem, not two. Your lifts create the stimulus, your food decides what your body does with it, and your weight trend tells you whether the plan is working. Most apps track one piece. Arrow connects all three. • Adaptive TDEE: Arrow estimates your real daily energy expenditure from your weigh-ins and food log, not just a formula, and keeps your calorie and macro targets adjusted as your body responds • Scale Weight vs. Trend Weight: every weigh-in is plotted against a rolling trend, so you can tell a water swing from true gain or loss before you change your plan • Oil detection: if a scanned meal was likely cooked in oil, Arrow asks before you log, so hidden calories don't slip past your numbers • Arrow Score: one number built from Strength (PRs and volume), Nutrition (calories, macros, weigh-ins), and Consistency (workouts and meal logs), weighted for your goal. A cut and a bulk are scored differently. • Estimated daily deficit or surplus and a four-week projection • Arrow Coach flags when a sudden scale jump or drop is likely water, not fat NUTRITION TRACKING THAT'S FAST AND HONEST • Smart Scan: photograph your plate and get the foods, calories, and macros • Describe a meal in plain words or by voice, scan a barcode, or look it up in the database • Heads Up before you log a scanned meal, and a meal score when you do • Edit any target yourself. Arrow never locks you into its numbers. • Recent foods, saved meals, custom foods, and copy-a-previous-day for meals you eat on repeat • Optional meal and post-workout reminders WORKOUT TRACKER BUILT FOR THE GYM • Log sets, reps, and weight in a few taps, no clutter mid-set • Plan your own routines or generate one from your goal, equipment, days, and session length • Flip any exercise card to see your history and personal records • Rest timer, dropsets, cardio and activity tracking • Custom exercises, swap exercises mid-workout, reorder on the fly • Lock Screen Live Activity and Dynamic Island keep your workout in view • Close the app mid-session and resume where you left off ARROW COACH Coach reads training and nutrition together: a recap of your week after workouts and on your Stats screen, a Heads Up on meals before you log them, and a call-out when a weight swing is likely water. Every note ends with what to do next. PROGRESS YOU CAN SEE • Muscle diagram shows which muscles you hit this week and how hard • Volume, PR, and lift progress over time • Week Overview calendar for training and nutrition days • Apple Health steps on your Profile and in Performance • Arrow Wrapped: your year in review TRAIN WITH FRIENDS • See your friends' workouts (and their meals, if they share them) in your feed • Share workout cards to Instagram Stories OPTIONAL GAMIFICATION Want extra motivation?

Track protein without turning meals into homework. Buff Kitty is a protein-only tracker for lifters who care about hitting one number every day. No calorie diary. No macro spreadsheet. Just your daily protein target, fast logging, and a gym cat that reacts as you get closer. Set your goal once, then log protein in seconds: - Quick-add the amounts you log constantly, straight from the dashboard - Type the grams when you already know them - Say what you ate when typing is annoying - Snap a meal photo and get an editable AI estimate - Scan a barcode for packaged food - Every estimate is yours to edit before it saves - Today's total, what's left, your streak, and recent entries on one screen Works the same whether you're bulking, cutting, maintaining, or recomping. Build a streak by hitting your protein target, and choose the reminder settings that work for you. Sign in with Apple or Google if you want to back up your protein target, food log, and Kitty progress, then restore them when you reinstall or change phones. Sign-in is optional. Manage your backup, email preferences, and account deletion in Settings. Buff Kitty is a subscription app. Setting your target is free, and a subscription unlocks tracking, the AI estimates, streaks, and the home-screen widget. AI estimates can be wrong, so check them before you save. This is a tracking tool, not medical advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
