## What is Heater Meter?

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.

### 5/5 — Great App for Youth Pitchers

*2026-10-26*

Really awesome tool to use while watching my son play 11U baseball. Easy to use and seems to be just as accurate as my pocket radar. Highly recommend for those looking for a quick option for training or documentation.

### 5/5 — ⭐️⭐️⭐️⭐️⭐️

*2026-10-26*

This is perfect for keeping up with my son’s pitching progress and logging his speeds. It’s so easy to use and much more convenient than carrying around a radar gun at practices and tournaments.
