Kaizer is the app where you train with your trainer or your gym: your routine, your classes, the chat and your progress, all in one place. WITH YOUR GYM If your gym runs on Kaizer, you join with the link they share and see the app with their name, logo and color. Book your classes or keep a fixed spot, read your gym's news and train with the routine they assign you. WITH YOUR TRAINER Your trainer sends you your routines, follows your progress, adjusts whatever needs adjusting, chats with you and asks for form videos. All of it in one place, without leaning on three other apps. NO TRAINER YET? Browse the marketplace inside the app. Every profile shows how that coach works, their specialties and whether they train online, in person or both. Subscribe to the one that fits and they are notified the moment you join. YOUR SESSIONS, IN DETAIL Sets, reps, load, rest. Supersets, circuits and dropsets when your plan calls for them. Every exercise ships with an illustration of the muscle it works, so you know what you are aiming at before you lift. ASSISTED PROGRESSION Week over week, Kaizer writes the loads of your upcoming sessions from what you actually lifted. You always know what to do when you walk into the gym, and the weight on the bar keeps moving. SMART REPLACE Machine taken? A movement you cannot do today? Kaizer suggests alternatives that keep the point of the exercise intact, so swapping one leaves the rest of the plan standing. EVERYTHING IN ONE PLACE - Direct chat with your trainer: text, photos, files and voice notes - Nutrition plan with meals, recipes and macros, when your trainer sends one - Full training history, streaks and progress your trainer sees too - 1,500+ exercises with illustrations - Apple Health sync and Live Activities while you train - Rest timer that runs on your lock screen TRAINING ON YOUR OWN? You can also use Kaizer without a trainer. Describe what you want in plain language (four days a week, bad knees, dumbbells only) and Kaizer builds a complete structured program in seconds, and keeps adapting it as you log your work. Kaizer works in Spanish, English and Portuguese, in 20+ countries. Terms of Service: https://kaizer.app/en/terms-and-conditions Privacy Policy: https://kaizer.app/en/privacy-policy

Sector Fit turns every run and walk into a battle for your city. The map is divided into sectors — named places, neighbourhoods, landmarks, and streets. Every kilometre you cover contributes to your group's control over the sectors you pass through. The more your group moves, the more of the city you own. HOW IT WORKS Start a run or walk and your GPS route is tracked in real time. Every sector you cross gets attributed to your group. Leaderboards show which group controls each sector, and groups compete for dominance across the entire map. JOIN A GROUP, DOMINATE THE MAP Create or join a group with friends, teammates, or coworkers. Pool your kilometres to take and hold sectors. Watch rival groups challenge your territory in real time and climb the leaderboard as your group's reach expands. BUILT FOR FAIR PLAY Pace validation prevents impossible speeds from being counted. Daily distance limits keep competition balanced. Anti-fraud checks ensure every kilometre is earned honestly. PRIVACY FIRST Location is only tracked while you are actively recording an activity — never in the background. Sign in with Apple, Google, or Strava, or create an account with email and password. Whether you run every day or take a casual evening walk, every kilometre counts toward your group's territory. Lace up and claim your city.
