INTVL: The World Is the Game. INTVL turns every walk, run or bike ride into a game played on the real world globe. The idea is simple. When you run or ride in a loop, the ground inside that loop becomes your territory. The bigger, smarter and more tactical your routes, the more of the map you hold. Claim your territory Every loop you complete claims real space. Other players are out there doing the same thing, so the map is always moving. You can take a new route to take new ground, or go back over an area to defend what's already yours. Play it your way Some people want to be the best in the world, so they chase the global leaderboard. Others care more about home turf and work to become the territory leader of their own suburb or city. Both are worth playing for, and you can switch focus whenever you want. Hold ground, win real prizes Every bit of the map you hold earns you entries into our competitions, where the prizes are real. The more territory you hold at the end of the competition, the better your odds. Run and ride with clubs Join a club and play as a team. Your territory adds to your club's total, so a good capture from you helps everyone you're playing alongside. A feed built around the game INTVL has a social feed where you can follow other players, see their activities, and cheer them on. It's a good way to find people around you and stay connected to other athletes around the world. Bring your own gear INTVL works with the devices you already train on, so your activities sync straight into the game: - Garmin - Suunto - Polar - Coros - Fitbit - Hammerhead - Wahoo We built INTVL to give a new meaning to fitness. Movement without stakes is just exercise. The world is the game. Take it. This app integrates with Apple Health (HealthKit) to show insights about your activity, including steps, heart rate, and previous runs.

About

Stimuli

Features
Read full description

Most trackers treat every set the same. Stimuli is a hypertrophy training app that scores the real muscle-building work in each set you log, tracks how recovered every muscle is, and builds programs that progress with you. Train with intent, and know whether your training is working. SCORE EVERY SET Log weight, reps, and RIR (in 0.5 steps) and Stimuli scores the stimulus each set delivers to every muscle it trains, not just the ones in the exercise name. Rows credit your traps. Belt squats spare your lower back. The model knows the difference. SEE RECOVERY, PER MUSCLE A full-body muscle figure shows what is fresh, what is fatigued, and what is ready to train again, derived from the work you have actually logged. PROGRAMS THAT GROW WITH YOU Generate a program with AI that matches your schedule, equipment, experience, and muscle priorities, or build your own from scratch. Weekly progress keeps your plan honest, and targets update from your logged performance. KNOW YOUR NUMBERS Estimated 1RM trends per exercise, weekly volume per muscle, and session summaries show trajectory, not just history. Deload guidance is grounded in a sustained decline in your strength trend, never guesswork. BUILT FOR THE GYM FLOOR Fast set logging, rest timers, per-exercise technique cues with illustrations, bodyweight and weighted movements handled properly, kg and lb support, and history synced across your devices. Available in 13 languages. YOUR DATA, YOURS Your training history and analytics stay yours to browse even if your subscription ends, and you can delete your account, and everything with it, right from Settings. STIMULI PRO Stimuli runs on a Stimuli Pro subscription. Start with a free trial and get the full app: live workout sessions, AI program generation, per-muscle recovery, and all your analytics. Choose monthly or yearly. The subscription auto-renews until cancelled, and you can cancel anytime in your App Store account settings.
