• Search techniques and keep your own notes alongside study references.
• Track practice counts and view techniques you have advanced to Demonstrated.
• Read about the nine Bujinkan schools, their histories, and training traditions.

• Set training goals, including daily repeating goals you can check off each day.
• Add selected goals to Apple Reminders.

CONNECT WITH YOUR DOJO
Optional Connected Dojo upgrades bring teachers and students into a private shared training space.
With Dojo Premium, approved dojo owners can:
• Invite students and manage membership requests.
• Create and publish a custom dojo curriculum.
• Share weekly schedules, individual classes, and special events.
• Review private event attendance responses.
• Create discussion topics and share announcements and dojo news.
• Record attendance, provide student feedback, and verify ranks.
• Add or replace video links for your dojo needs
With Student Unlock, approved students can follow their dojo’s published curriculum, view schedules, respond to events, join private conversations, and access teacher feedback and dojo study resources.
Student Unlock is a one-time purchase that stays with your app account when you change dojos. Connected features require active membership in a participating dojo and an active owner subscription. Purchases do not grant teacher or owner status.
EXPLORE YOUR COMMUNITY
Discover public dojo listings, follow news sources that interest you, explore events, and optionally share a community profile with other practitioners. Take a break with the Shuriken Challenge, a game of focus and timing.
YOUR PERSONAL RECORDS, YOUR RESPONSIBILITY
Your personal journal, training history, technique notes, and media stay on your device rather than being automatically uploaded to a cloud training account.
Automatic local save history keeps up to seven days of recovery copies. Export and import tools let you create separate backups of your records and attachments. Your app data may also be included in an iCloud device backup when enabled in your iPhone’s settings.
PURCHASE INFORMATION
The app purchase includes personal training tools, the standard curriculum, study guidance, library, public dojo directory, and personal progress tracking.
Dojo Premium is an optional auto-renewing monthly subscription. Student Unlock is an optional one-time purchase. Prices are displayed in the app for your region.
Subscription payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel subscriptions in your Apple Account settings.
