Call every pitch from the dugout and win every count. NextStrike turns your phone into an easy pitch-calling system. Tap the pitch, tap the location, and your catcher hears the call in their earpiece ("Slider, up and away") before the batter digs in. No hand signs, no wristband cards, nothing for the other dugout to read. Built for baseball and softball coaches from 9U to college. WHY COACHES SWITCH - Calls in under a second. Tap your phone instead of touching your face or arm, and the call is in your catcher's ear. - Private by design. With an earpiece connected, calls play only in your catcher's ear, so your dugout and the other bench can't hear them. - No hardware to buy. Works with Bluetooth earbuds your catcher already owns. - More than a walkie-talkie. Pitcher arsenals, pitch counts and outcome tagging are built in. EVERY PITCHER'S ARSENAL Set up each arm on your staff with the pitches they actually throw: four-seam and two-seam fastballs, slider, cutter, sinker, changeup, splitter, curveball, knuckleball or a custom pitch. Call locations by number (zones 1 to 9) or by name (up and away, down and in) when you want to paint corners. Pick-off and shake are one tap away. SEE WHAT WORKED, PITCH BY PITCH - A full pitch log for every pitcher, organized by game and inning - Tag each pitch as a strike, ball, foul, hit, out, error or hit by pitch - Innings advance after three outs, and pitch counts keep themselves - Game summaries with strike rates to review between starts TALK TO YOUR CATCHER Hold the mic to send your voice straight to your catcher's earpiece between pitches: "3-hole is on deck," "let's steal an out with a back pick," or anything you'd usually shout from the dugout. If a call gets missed, replay one of your last three calls with a single tap. ONE ROSTER, EVERY COACH IN SYNC Invite your assistants and pitching coach at no extra cost. The head coach subscribes, and the whole staff works from the same roster and pitch history. Run up to three teams, like JV and varsity or several travel age groups. WORKS AT ANY FIELD Pitch calling keeps working without a signal, and calls sync when you're back online. The voice that reads each call runs on your phone, not over the internet. PLANS - Free: try pitch calling in the demo, and join a Pro coach's team as an assistant at no cost. - Pro: $99.99 per year or $14.99 per month, with a free trial. Up to 3 teams, 30 players per team, 3 coaching licenses, full pitch history, offline calling and Hold to Talk. - Organization: custom plans for programs with many teams. Contact us through the support link. REQUIREMENTS An iPhone or iPad for the coach, and any Bluetooth earbuds for the catcher. Call it, coach it, win it.
