> CoachAI turns an iPhone into a form-checking personal trainer. Prop up your phone, and it uses the camera plus on-device AI to watch you exercise, counting every rep, reading your form in real time, and flagging when your technique breaks down, all without a coach standing over you. The privacy angle is the quietly important part. Because the analysis runs on the device, your workout video is not shipped off to a server, which is reassuring for something that is literally watching your body. Beyond the live feedback, it builds equipment-free workout plans tailored to you, so you do not need a gym membership or a rack of machines to use it. It is the kind of narrowly useful AI product that is easy to root for: it takes one thing people genuinely struggle with, exercising with correct form and without an expensive trainer, and does it in your pocket. With a solid early rating and a small, focused review base, it is worth a try for anyone who trains alone and worries they are doing it wrong.
