Your iPhone can help you become a better tennis or golf player. You are just going to need the right app and a decent wearable to track your performances. Sweet Spot happens to be a golf & tennis tracker that aims to make practice fun again. It uses games, lessons, and challenges to improve your game and keep you entertained. Each Sweet Spot ships with one sensor, a clip that attaches to the grip of your golf club and a sleeve that attaches to the end of your tennis racquet. This is a Bluetooth device, so you just have to bring your phone along to view and analyze your data.
Sweet Spot not only tracks your practice sessions but also encourages you to do more by gamifying practice. You can practice alone or with friends. Its games teach you basic shots, including volley, serve, upswing/downswing, and more. Sweet Spot is compact and based on an innovative idea. It is available on Indiegogo right now.
