STK Callout is the pickleball score keeper for open-play doubles. Tap the side that won the rally and your iPhone calls the score out loud: 4-2-1, every serve.
From the first serve to the last lesson of the night, this is how a day of doubles goes with STK Callout on the fence.
The app opens on the court, ready to tap. The top half is one team, the bottom half is the other, and each half is the button. Quick Setup remembers your last game and the last eight names, so a repeat game is two taps: open it, Start.
Doubles starts on the second server, so the first call is 0-0-2. Try it here: tap the team that won each rally and watch the call change, the way it does on the court.
With Voice on, your browser reads each call aloud, like the app does. Side-out scoring, game to 11, win by 2.
A long dink rally, and nobody is sure any more. The call settles it: serving score, receiving score, server number, read before every serve. Tap the strip to hear it again, or hold it to see the last five calls.

In a tournament-style game, STK Callout flags the switch when a side first reaches the midpoint, says it out loud, and one key flips the halves so the phone still matches the court.
The game is saved the moment it ends: winners, final score, length and every rally. Next game keeps the same partners; Rotate moves everyone one place. Today keeps the whole session in order, with who you played with.
Scoring Coach has five two-minute lessons: who serves first, what 0-0-2 means, side out vs point, the second server and when to switch. Watch the rally on a mini court, pick the call, earn XP. A lesson day keeps your court-day streak alive.
It reads every call out loudPlain numbers or Referee style, slow, normal or fast. It speaks over the silent switch and lowers your music while it talks.

It keeps your court-day streakA 21-day chain, a weekly goal from 1 to 7 court days, your win rate with each partner and your longest run of points.

Games, partner and opponent names, lesson progress, streaks and settings are saved on your iPhone. They are never uploaded. Clear history in Settings deletes them.
STK Callout uses Firebase Remote Config (by Google) to fetch its app settings, such as whether to show an occasional message at launch. Firebase creates a random installation ID for this. It is used only to make that feature work, is not linked to you and is not used to track you.
No location, contacts, microphone or photos. The voice is your iPhone’s own text-to-speech, spoken on the device. Scoring works with no connection at all.
