Heater Meter measures pitch speed with your iPhone's slow-motion camera. No radar gun, no sensors, nothing to attach to the ball. Prop your phone on a fence, tripod or bucket, tap Record, throw, and tap Stop. Seconds later you get the speed, how sure the app is of it, and the ball's path drawn over your own video. WORKS FROM BEHIND THE BACKSTOP Most video apps need you side-on. Heater Meter can also read a pitch coming toward you, by measuring how the ball drops under gravity. There's no mound distance to enter and nothing to measure. SEE THE FLIGHT The pitch's path is drawn over your footage. Scrub along it and a zoom window shows the ball in every frame, so you can check exactly what was measured. BULLPEN MODE Prop the phone up, tap Start and throw. Heater Meter calls each pitch, records it, says the speed out loud and goes again until you stop, then shows the top speed, the average and every pitch. PLAYERS AND PERSONAL BESTS Pick who's throwing and every reading is kept under their name, with their best, their average and a progress chart. A new personal best keeps its video automatically. SHARE A PITCH Turn a pitch into a slow-motion video with the speed on it, ready to send to family or post. BASEBALL OR SOFTBALL Measure a baseball, or a 12" or 11" softball. HONEST NUMBERS Every reading shows its ± margin. When the video can't support a clean number, the app tells you instead of guessing. YOUR RECORDINGS Your last 10 recordings are kept with their readings, so you can look back over a session and compare pitches. Star any recording to keep it for good. PRIVATE BY DESIGN Video is analysed on your iPhone. Nothing is uploaded, and there's no account to create. TIPS FOR THE BEST READINGS • Keep the phone still: a tripod, fence or bucket works. • Film in good daylight. • Keep the whole flight, from the pitcher's hand to the catcher's mitt, in the picture. PRICING Your first 10 readings are free, with every feature. A reading only counts when it produces a speed. After that, Heater Meter Pro is $4.99 a month or $29.99 a year for unlimited readings. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in Settings > your name > Subscriptions.
