What this app does, and what it does not do
BadmintonPeak does not keep score, does not manage your club, and does not book courts. It does one thing: turn a video of your play into corrections. You film a rally, a drill, or a match sequence with your phone, send it from the app, and within minutes you receive a report that timestamps every shot, describes what it sees, and tells you what to change, with the exact moment to watch it. Around this core, the app features online courses where each step is validated by a graded video, a coach who remembers your analyses and answers your questions, and the Smash Challenge which measures your smash speed. Everything is designed for the player who trains without an outside eye on their movement.
What you send
A phone video, filmed in landscape, or a YouTube link. For a technique, place the phone on the side of the court at hip height; for a rally, behind the court. Thirty seconds are enough for a stroke, a few minutes for a match sequence. Your entire body, the racket, and the shuttlecock must stay in the frame; a tripod is unnecessary, a bag or a bench is enough. From the app, you choose what you want to look at, a specific shot or the reading of a rally, and the player to follow if there are several people in the frame. The video stays in your account, private, and can be deleted with one tap.
What you receive
A report in the app, in a few minutes for a short sequence, a bit longer for a match: the list of your shots with the timestamp of each one, an observation for every shot that matters, flaws sorted by frequency, and a concrete correction for each. On a drill set, the report counts repetitions and compares the best to the worst. Your history keeps every analysis, and Coach Peak relies on it to answer you: ask him what to work on this week, he starts from what he saw in your videos, not from generic advice. The courses then cover each stroke, one step at a time, with a graded video for each step.
Courses and coach, in the same app
An analysis tells you what is wrong; courses tell you how to fix it. Each course covers a stroke or a situation, the smash, the short serve, the split step, the smash defense, in short steps: a guideline, a drill to film, a grade on your video with points to improve. You progress at your own pace, the next step opens when the previous one is validated. Coach Peak lives right alongside in a chat thread: he has read your analyses and your steps, he suggests what to work on this week and answers when you show him a rally. Finally, the Smash Challenge measures your smash speed on a side video and ranks you against other players during the season.
Who it is for
For the club player who wants to progress between sessions, for the one who does not have a coach, and for the competitive player who wants to understand a lost point. The app also serves the coach who wants a tool to support their instructions: the report can be shared with a link. You start for free, with free analysis minutes upon signup and the first step of each course, without a credit card. Monthly or annual subscriptions add minutes every month and full access to the courses; you cancel whenever you want, from your profile. The same accounts and the same analyses can be found on iOS, Android, and on the web.
