## What is Sparr?

A virtual boxer throws punches at you. You slip, block or duck for real, and your iPhone's camera judges every defense.

Stand your phone up at chest height, step back about two big steps, and the round starts. No partner, no bag, no gloves, nothing to wear. Just you, your phone and a bit of space.

Made for anyone who boxes or wants to: beginners learning head movement, and fighters training alone at home between sessions.

HOW A ROUND WORKS
• He throws: jab, cross, hooks to the head, uppercuts to the body.
• You defend: slip, block, parry, duck or pull back.
• Every punch gets a verdict on the spot: Defended or Hit.
• If the camera couldn't see a punch, it says "Not measured" instead of counting it against you.
• After the bell, see what you defended, what got through, and the punch that gave you the most trouble.

THREE WAYS TO TRAIN
• Single punches: one punch at a time. Read it, defend it.
• Shadowboxing: your corner calls a combination, you throw it at the mitts, and Sparr checks each called punch, in order.
• Fight flow (Contender): combinations of two to four punches coming at you.

ROUND OF THE DAY
No time to set anything up? One tap starts today's round, picked for you from your level. It changes every day.

MAKE IT YOURS
Chill, Standard or Intense. Four opponent styles. Rounds of 1 to 3 minutes. Survival mode, where three hits end the round. Sessions of up to 12 rounds with rest between them (Contender). The corner's voice, the bell and the music keep time, so you can train with the phone across the room.

A RATING YOU EARN
Every scored round moves your defense rating, from 0 to 1000, through five ranks: Rookie, Amateur, Fighter, Pro and Champion. Your history and progress show your record and your weak spots over time.

STAY CONSISTENT
Set a weekly goal and a daily reminder, and keep your weekly streak alive. A Home Screen and Lock Screen widget shows your rating, your rank and your week.

YOUR VIDEO STAYS ON YOUR PHONE
Tracking runs entirely on your iPhone. Camera images and body positions are never uploaded or saved. Your account keeps your round results, never footage. Download your data or delete your account at any time from the Account tab.

FREE TO START
• Your first round is free: one minute, no account.
• Then create a free Sparr account with a code sent to your email (no password). It keeps your round, your rating and your progress.
• Unlimited training needs Contender: unlimited rounds, every mode, sessions of up to 12 rounds, full history and defense insights.
• Two ways to get it, both in the app: Contender monthly, or the Lifetime Pass, paid once, with a limited number of places.
• Your plan stays on your Sparr account, so it works on every iPhone you sign in on.

What you need: an iPhone with iOS 26, room to step back, and decent light. Sparr is solo practice. It does not replace a coach or real sparring, and its feedback is an estimate from the camera. Train in a clear space, on a non-slip floor, and stop if you feel pain.

PURCHASE TERMS
Contender is an optional auto-renewable subscription of 1 month. Its price is shown in the app, in your local currency, before you confirm. Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel it in Settings > [your name] > Subscriptions. Deleting your Sparr account does not cancel an App Store subscription.
The Lifetime Pass is an optional one-time purchase, not a subscription: it makes your account Contender for as long as Sparr offers Contender, and nothing renews. The app shows how many places are left.
