Simple Shot Timer

Simple Shot Timer is a clean, no-nonsense shot timer for dry-fire and live-fire practice. Made for practical shooters who want fast feedback, accurate splits and a full history of their drills, without ads, tracking or accounts. DRILL MODES • Standard: open string. Beep, shoot, tap STOP. Splits and total time on screen. • Par: set a par time and the number of cycles. Each cycle has its own start and end beep, with an optional rest interval between cycles. • Stage: a long single-window timer up to 200 seconds for stage walk-throughs and scenario practice. START DELAY Instant, fixed, or random within a min/max range. SAVED DRILLS Save the drills you run often (mode, start delay, par and stage timing) under a name, and load any one with a tap. SHOT DETECTION • Listens through your phone's microphone and picks out each shot as it happens. • The start and par beeps never count as a shot, a shot fired during the beep still does, and an echo filter keeps one shot from counting twice. • The clock starts when the mic hears the beep, so speaker lag never ends up in your times. • Auto-configure: fire a few shots and the app suggests a sensitivity and frequency band for that gun and range. • A mic test screen with a live level meter lets you dial in sensitivity before going hot. • Add shots by hand at any time, after the string or in review. HISTORY & REVIEW • Every string is saved automatically (rolling cap from 50 to 5000, default 500). • Review each string with split times, first shot, fastest, slowest and average. • Editable label, notes and penalty per string. CSV EXPORT Export a single string or your whole history as CSV through the share sheet: email it to yourself, save it to cloud storage or open it in a spreadsheet. KEEPS RUNNING Lock the screen or switch apps mid-string: the timer keeps detecting shots and playing par beeps. PRIVACY FIRST • 100% on-device. No accounts, no cloud, no analytics, no ads, no tracking. • The microphone is used live, in memory, only while the app is listening (a string, the mic test or auto-configure). No audio is recorded or sent anywhere. • Delete all your data and settings from Settings at any time. • Open source (GPL-3.0): the full code is on GitHub at github.com/Mr-Jami/simple-shot-timer, so you can check every claim above. QUALITY OF LIFE • Screen flash on the beep for loud ranges and heavy ear protection, plus optional haptics. • A notice warns you if the media volume is muted while a string runs. • Keeps the screen awake during a string. • Monochrome Material 3 theme with System, Light, Dark and High-contrast options. LANGUAGES English, Finnish, French, German, Polish, Portuguese, Russian and Spanish. PERMISSIONS • Microphone: required for shot detection. Requested the first time the mic is needed. • Notifications: on Android 13 and later, needed for the notification that keeps the timer running in the background. • Vibration: optional haptic on the beep. • Wake lock: keeps the screen on during a string. Built for the range, the dojo and the basement dry-fire setup. Free, lean, no upsells.
