Most people determine whether a soccer is inflated enough by feel. You squeeze the ball and bounce it a little bit and if it feels great, that's it. But a perfectly inflated soccer ball can have a positive impact on your game. Fortunately there's an app for that. Balltune uses the sound the ball makes when you bounce it on a hard surface to calculate its pressure without a physical gauge and comes up with inflation recommendations. Higher pressures for power and lower pressures for control and accuracy. Available for both iOS and Android devices.
