Welcome to Furbol, the platform transforming the way we organize and join football games! Drawing from the aesthetic of 8-bit video games, Furbol makes finding the perfect match as simple as typing on your keyboard. No matter where you are, with Furbol you can find, join, and even host REAL football games globally! You can play private games with friends or public games with total strangers. Plus a solid peer to peer rating system after the game makes sure players will earn their reputation in terms of skills, reliability and behavior. Furbol breaks away from traditional game setups and offers a brilliant and flexible user experience with features unique to our platform: **Game Hopping** Why limit yourself to one game? With Furbol, you can book spots in multiple games, even on the same day. If one of your games gets sold-out, you'll automatically be removed from all other games - keeping your schedule clear and your options open. **No Penalties** Tired of being locked in a game? Furbol lets you join and leave games at any time without penalties. Plus, you can bring along external users to play your games. **Choose Your Position** Select your preferred position in the field, and play your game, your way. Plus, goalkeepers never pay anything to play! **Play Anonymously** Only your reputation matters in Furbol. You can play anonymously, allowing your stsidricis to do the talking. **Be A Host** Anyone can be a host on Furbol, and host games. Even sports centers can let other hosts buy out and take over their games. **Transparent Participation Fee** Our unique system ensures you're charged a fair participation fee based on the actual number of players and goalies on the field. Goalkeepers play for free, and can even be hired for a fee! **Fair Rating System** Experience an anonymous, non-mandatory peer-to-peer rating process that lasts only 4 hours after the game - ensuring honest feedback and player respect. Furbol's rules are designed to keep the game fair and fun, from registration to participation. And our self-sustenance model means we're rewarded by our players, not through intrusive ads or hidden fees.

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
