The log book that runs your workout. APX Tempo isn't another timer, and it isn't another spreadsheet with a gym logo. It's a training diary with a voice — it counts you in, calls your work and rest, and writes the session down so you never have to remember what you did last time. Terms of Use: https://apx-legal.vercel.app/terms Privacy Policy: https://apx-legal.vercel.app/privacy QUICK TIMER, FREE Open the app, set a work interval and a rest interval, go. No account. No signup. No setup screen between you and your first set. The free tier is a real timer, not a demo. YOUR LOG, KEPT AUTOMATICALLY Finish a workout and it's recorded — nothing to type after the fact. What you ran, how long, and when: streaks, a color-coded week strip, and all-time training totals. Your history is a training record, not a feed. AUDIO THAT COACHES THE SESSION "Get ready — 3, 2, 1, GO." Spoken cues and chimes on every transition, built for a loud room — so you keep your eyes on the bar instead of your phone. Cues keep firing with the screen locked, your phone in your pocket, and your own music playing, never pausing or ducking your playlist. Full audio, chimes only, voice only, or silent. BUILT FOR HOW LIFTERS ACTUALLY TRAIN Multi-exercise circuits with distinct work, rest, and round-reset phases. Single-limb and staggered set support. Set it once, save it, run it every week without touching anything. FULL DETAIL, ON YOUR CALENDAR Optional calendar sync writes every completed session to your calendar with the whole story: work, rest, and round-reset structure, sets per exercise, your exercise list, and real elapsed time. Tap last Tuesday and see exactly what you did. BUILT FOR THE ENVIRONMENT IT'S USED IN Dark interface that doesn't blind you in a dim gym. Controls big enough to hit with chalked hands. No ads, no notifications guilting you into a workout. It does one job and gets out of the way. APX TEMPO PRO Pro unlocks unlimited saved custom timers, multi-exercise circuits and phase sequencing, the full audio cue engine, session history, and calendar sync. $4.99/month or $29.99/year with a one-week free trial, or $59.99 one-time lifetime. Quick Timer stays free forever, with or without Pro. PRIVACY No account required. No advertising. Your training data stays on your device. APX Tempo is the log book layer of the APX training system — the first of a connected set of tools built for people who train seriously and want their data to be useful instead of decorative. APX Tempo Pro subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation of purchase. Manage or cancel in your Apple ID account settings. Lifetime is a one-time purchase and does not renew. Questions or feedback: Jesse@apex-precision-training.com

Sound Cue is a custom interval timer for workouts that need more than a last-second beep. Place spoken countdowns or beep cues exactly where you need them—early enough to prepare, change equipment, reset, or breathe before the next effort. BUILD EACH PART OF YOUR WORKOUT Choose how many timed work intervals (reps) and sets you want, then time Get Ready, Work, Rest, and Between Sets independently. Build a simple round timer or use Sound Cue for HIIT, Tabata, boxing, circuits, mobility, cardio, climbing, and more. PLACE CUES WHERE YOU NEED THEM Add up to five sound cues to each workout part: Get Ready, Work, Rest, or Between Sets. For each cue, choose a beep or spoken number. Each cue can play once, every second as a countdown, or on a custom repeating schedule. Set when it begins and whether repeating cues stop after a chosen count or continue until that workout part ends. FOLLOW ALONG BY SOUND Start the timer and stay focused on your workout. Phase announcements and scheduled cues tell you when to work, rest, and reset without checking the screen. STAY IN THE FLOW • Track time remaining, the current set and rep, completion percentage, and the next interval at a glance. • Choose beep or voice alerts—or turn them off—for interval changes and workout completion. • Adjust sound volume, turn haptic feedback on or off, and choose whether cues briefly lower music or other audio. • Hear scheduled cues while your iPhone is locked or while using another app. SAVE AND ORGANIZE WORKOUTS The free library starts with three included workouts and holds up to five saved workouts in total. Rename, reorder, edit, and reuse them. Use named groups to keep related workouts together and easy to find. A one-time in-app purchase expands the limit to 100 saved workouts. PRIVATE BY DESIGN Sound Cue has no ads, analytics, or tracking. Workouts, cues, and preferences are stored locally and are not transmitted by Sound Cue. Build your intervals, press Start, and let Sound Cue keep you moving.
