About Calfmaxx
Calfmaxx turns calf raises into a real training system. Calfmaxx requires a paid subscription. A free trial is available; after the trial, all features require an active Calfmaxx Pro subscription. Most people skip calves or do them with terrible form. Calfmaxx fixes both. Prop up your phone, step into side view, and the camera counts every valid raise — full range only. No cheating. No guessing. Rep counting runs entirely on your device. Your camera feed is analysed in real time and immediately discarded — nothing is recorded, saved, or uploaded, and no video ever leaves your phone. What you get with Calfmaxx Pro (subscription required): • Automatic on-device rep counting with form feedback • Daily ranked challenge (60-Second Burnout) with Today, This Week and This Month leaderboards • Weekly boss fights that carry damage across sessions • Soleus and single-leg variations • Streaks, ranks, and a transparent Calf Score • Simple “Start Raise” sessions for everyday volume Your Calf Score combines your best Burnout, training consistency, and lifetime volume so you can see real progress — not just vanity metrics. Whether you’re trying to fix skinny calves, build diamond shape, or finally stop neglecting your lower legs, Calfmaxx makes the work measurable and addictive. No equipment needed. Just you, your phone, and honest raises. SUBSCRIPTION Calfmaxx Pro is required to use the app and is available as a weekly or annual auto-renewing subscription. Prices are shown in the app before purchase and may vary by region. If a free trial is offered, any unused portion is forfeited when you purchase a subscription. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. Manage or cancel your subscription in Settings › Apple Account › Subscriptions.

What’s new
Version 1.0.1 · Updated October 7, 2026
• New workouts: Soleus Grind (bent-knee) and Single-Leg Standard, which alternates legs and labels which one is up • Leaderboards now show Today, This Week and This Month for the 60-Second Burnout • Timed challenges wait until you're locked in frame, then count you in for 10 seconds, so the clock never starts while you're still walking into place • Stability and performance fixes
