Someone in your corner, calling the shots. Shot Caller is a Muay Thai round timer that calls techniques out loud while you train. Set your rounds, pick a style, put the phone down. You keep your hands up and your eyes forward, and the app calls the next shot. No counting reps in your head. No stopping to read a screen. Just the bell, the callout, and the work. TRAIN THE WAY THE SPORT IS ACTUALLY FOUGHT Eighteen styles, each with its own vocabulary: - Nak Muay Newb - free, and where most people start - Muay Mat - heavy hands and low kicks - Muay Tae - the kicking specialist - Muay Khao - clinch work and knees - Muay Femur - the technician - Muay Sok - elbows - Meat & Potatoes - the high-percentage basics - Buakaw's Corner - pressure and the left kick - Low Kick Legends, Elbow Arsenal and KO Setups - Feints and Fakeouts, The Answer Back and Two-Piece Combos - Boxing, Dutch Kickboxing and Southpaw for cross-training Pick one or stack several, and the callouts change with them. Nak Muay Newb and freestyle are free; the rest come with Pro. START FROM ZERO Ten guided levels take you from your first jab to full combinations, one technique at a time. Each level introduces the shot, drills it, then folds it into everything you have already learned. KNOW WHAT YOU ARE THROWING 35 techniques and 48 combinations, each with what it is for, how to throw it, and the mistakes that make it miss. BUILT FOR REAL SESSIONS - Shadow boxing, heavy bag, or pads with a partner - Rounds, round length, rest and difficulty all yours to set - Southpaw mode - Optional calisthenics between rounds - Every session logged, with streaks and achievements FREE TO START The round timer, freestyle callouts, the Nak Muay Newb style and the first level of the guided path are free, and always will be.

Verdict
Boxing Interval Timer and Shot Caller both sit at 4.8 stars, but that hides the real split: 100% of Shot Caller's written reviews are positive against 59% of Boxing Interval Timer's. Shot Caller also leads on ads (none vs shown) and update cadence (weekly vs every 3 months). Boxing Interval Timer's advantage is ratings volume (13K vs 6) and monetization model (free with in-app purchases vs paid). On price, rating, in-app purchases and device support there is nothing between them.
