Private beta · iOS & Android

Train with purpose.
Every minute counts.

X4X is built around timed circuits (EMOM-style: work that fits the minute), a guided session timer, and programs that put your next workout on the calendar. We’re in private beta on iOS and Android — not on the public App Store or Play Store yet.

Free while we’re in beta. Spots are limited so we can support early testers well.

What “beta” means here

The timer, circuits, programs, and exercise library are real and already in daily use. Builds still move fast — expect rough edges, and a short path to tell us what broke.

  • Invite only — we add testers in small batches
  • iOS & Android — TestFlight and Android beta installs
  • Your feedback shapes the app before a public launch

How X4X works

Four building blocks — from a single movement to a multi-week plan.

  1. 01

    Exercises

    Hundreds of movements (bodyweight, free weights, machines, and more) ship in the app — or add your own.

  2. 02

    Circuits

    Timed blocks where one or more exercises rotate set by set. The clock keeps the structure honest.

  3. 03

    Workouts

    A full session: circuits in order, with optional warmup and cooldown routines attached.

  4. 04

    Programs

    Multi-week plans on your schedule so Home already knows what’s next.

Built for intentional training

Less deciding in the gym. More finishing the session you planned.

Guided timer

Per-set countdown, rep and weight logging as you go, then a clear session summary when you finish.

Home that knows what’s next

Enrolled programs, today’s plan, and a daily circuit spotlight so you open the app and train — not rebuild the week.

Warmups & cooldowns

Real routines you attach to a workout — not a sticky note on the side.

Train with people you trust

Friends, live spotting during a session, groups, and coach–client tools when you need them.

Simple start, room to grow

A calmer library for beginners; deeper builders and advanced controls when you’re ready — same app.

Library on your phone

The built-in exercise catalog ships with the app so you’re not stuck searching mid-set when the gym Wi‑Fi dies.

Early access

  • iPhone (TestFlight) or Android phone
  • Willingness to send blunt feedback when something feels off
  • No credit card — beta access is free
