UnderDog is the gym app that actually feels like your gym. Track workouts, compete on your gym's leaderboard, connect with lifters who train where you train, and get coached — all without the clutter.
Most gym apps are built for everyone. UnderDog is built for your gym. Here's what makes us different.
Compete on bench, squat, and deadlift rankings at your actual gym. See who's the strongest where you train. Other apps show you global feeds of strangers — we show you who's lifting next to you.
Your feed is your gym. Follow people who train where you train, not random accounts. Share workouts with people who'll actually spot you tomorrow. This isn't social media — it's your gym's network.
Find a coach, get custom weekly programs delivered right into the app, and start training with pre-loaded workouts. No separate platform, no PDFs, no back-and-forth on WhatsApp. Everything in one place.
We don't have 400 exercises with tutorial videos you'll never watch. We don't have 15 chart types. We built what serious lifters actually use — fast logging, clear progress, and real competition — and left out everything else.
Most workout apps connect you to random people worldwide. You'll never train with them, never compete with them, never see them at the squat rack. It's social media dressed up as fitness.
Meal tracking, yoga timers, running routes, meditation, calorie counters, body scan integrations. They try to be everything for everyone and end up being average for lifters.
Everything you need to train smart. Nothing to get in your way.
Weight, reps, RPE. Auto-fill from your last session. Set types for warmups, drops, and failure sets. The fastest way to track your lifts on iOS.
Bench. Squat. Deadlift. See where you rank at your gym and globally. Separated by gender. Updated in real time as you hit new PRs.
Follow lifters at your gym. Share workouts, post updates, and build a crew. Three feeds: Following, Discover, and My Gym.
PR tracking, volume charts, and complete workout history. Clear data on how you're improving — no analytics degree required.
Save your favorite workouts as templates. Build multi-week programs. Follow structured training without the spreadsheet.
Message lifters directly inside the app. Talk training, share tips, coordinate gym sessions. No need for external apps.
No separate coaching platform. No spreadsheets. No PDFs over email. Find a verified coach, get custom programs delivered weekly, and start every workout with your sets already loaded.
Coach your clients from anywhere. Write weekly programs, see exactly what they lift, communicate directly, and get paid monthly. Register as a coach inside the app — we'll review your profile within 48 hours.
