Help Center

Open the app or visit karatehost.com/app, tap Sign Up, enter your email and password, and verify your email. You'll be set up as an Admin account with full control.

Admin has full control — create tournaments, manage students, add co-admins, delete data, and access all features. Co-Admin is assigned by the Admin to help run specific tatamis — they can score matches and update results but cannot delete data independently. Viewer can watch live match scores (requires tournament access purchase).

Yes. Admin accounts can be logged in on multiple devices simultaneously. Co-Admin accounts can also be used on any device. All data syncs in real time through the cloud.

Go to Settings → Language in the app. Available languages are English, Hindi, Tamil, and Malayalam. The change takes effect immediately.

Go to Students → Import. Download the template first, fill it with student data (Name, Belt, Age, Weight, Gender, Club), then tap Import Excel. Duplicate names are automatically detected and skipped. Free accounts can import up to 50 students total.

💻 Tip: the Excel import is much easier on a computer than on a phone — open karatehost.com/app on a laptop to fill and upload your roster in a couple of clicks.

The template includes: Name (required), Age, Belt, Weight (kg), Gender (Boys/Girls), Team/Club/School (club, dojo, or academy name), Kata (yes/no), Kumite (yes/no).

Use the sheet named Students. Other sheets (instructions) are ignored on import.

⬇ Download Excel Template

Go to Students and tap Renumber. This reassigns chest numbers in order (1, 2, 3…), filling any gaps caused by deleted students. A confirmation dialog appears before changes are made.

In Settings → General, enter host, venue, and date. Create tatamis (free plan: usually 1). Optionally use Import Demo Settings for a full brochure-style sample (ages, weight groups, belt groups) without changing tatamis. Then configure Kata and Kumite tabs, add students, and Shuffle.

📖 Full walkthrough: How to Conduct a Karate Tournament →

A pool (set) is one competition group — for example Boys 11–12 Under 35 kg Below Brown (kumite) or Girls 13–14 Intermediate (kata). Each pool has members, AKA/AO bracket matches, and prizes. Unlimited pools per tournament after shuffle.

Open Students → Shuffle & Generate. Choose Kata and/or Kumite, tatamis, and pool size. The app builds pools as:
• Kata = Gender + Age + Novice / Intermediate / Advanced
• Kumite = Gender + Age (if ON) + weight group (range) + Below Brown / Brown & Above
AKA/AO sides are assigned for both events. Do not reshuffle after matches start.

Yes. Shuffle both events; pools appear under KATA and KUMITE on the Pools screen. Assign tatamis per event. Free users can still run both on one tatami (at different times).

Open a kumite pool match → START MATCH. Score AKA/AO with +1 / +2 / +3, fouls (C1–C3, HC, H, S), and Senshu. Declare the winner to advance. Viewers can open WATCH LIVE on the same match.

Yes. Each score control supports remove/decrement (long-press or minus where shown). You can adjust scores and fouls during an active match before declaring a winner.

Scores are saved locally in offline mode. An indicator appears when you're offline. All data syncs automatically to the cloud once connectivity is restored. No match data is lost.

Kata uses the same pool/bracket style as kumite. Open a kata pool → assign AKA and AO → START MATCH. One dual screen shows both sides. Pick the kata name from your Settings → Kata list, enter J1–J5 for each side, then declare the winner (or Finish by Score). Scores update live for viewers on the same screen.

WKF (drop highest and lowest of 5 judges, sum the middle 3) or Total Sum (add all 5). Set this in Settings → Kata → Scoring Format before the event.

Typical brochure setup: Novice (White, Yellow, Orange), Intermediate (Green, Blue, Purple), Advanced (Brown, Black). These are separate from kumite’s Below Brown / Brown & Above. Rank belt is on the student; AKA/AO is only the match side after shuffle.

Each weight category is a group (min–max range), not one class per kg. Flyer “−35 / −45 / +45” means Under 35, 35–45, and Over 45 for that age. Bands can be scoped by age and gender so boy/girl cuts match your brochure.

Go to Settings → Co-Admins → Add Co-Admin. Enter the co-admin's email address (they must already have a Karate Tournament App account). Assign them to a specific tatami. They will see the tournament on their next login.

Co-admin can: Score matches, update kata scores, view all tournament data, manage their assigned tatami. Only Admin can: Delete any data, create/edit tournament structure, add/remove co-admins, access billing and settings, export reports.

In-app Reports: Tournament Summary, Student Roster, Bracket View, AKA/AO Sides (Kata and Kumite), Match Summary, Team Overall, Pool Print. Most export as print-ready PDF. Score sheets (blank judge forms) are printed from the Pools screen.

Go to Settings → Subscription and tap Upgrade to Premium. Premium includes unlimited students and multiple tatamis (plus multiple co-admins and watermark-free PDF reports). Free plan is limited to 50 students and 1 tatami.

The Wallet lets you add points (via in-app purchase) and use them to unlock premium features or tournament viewing access. Points can also be transferred to other users. Check your balance in Settings → Wallet.

No. Premium is a one-time payment — it does not auto-renew. After 30 days it simply expires and you return to the free plan. You can repurchase anytime you need it for your next tournament.
