## What is GrappleOS?

GrappleOS is the operating system for Brazilian Jiu-Jitsu gyms and the athletes who train there.

FOR ATHLETES
• See your gym schedule, favorite classes, and announcements.
• Check in with GPS, a gym QR code, or your athlete QR code.
• Track weekly goals, streaks, achievements, and a detailed training history.
• Join gym and platform challenges, climb leaderboards, and celebrate milestones.
• Connect with Mat Friends, share selected training activity, and control your public profile.
• Keep a private training journal and tournament record, or import public Smoothcomp competition history without sharing your password.
• Manage memberships, waivers, belt progression, and multiple gym affiliations.

FOR GYM OWNERS AND STAFF
• Run rosters, classes, attendance, schedules, announcements, challenges, waivers, and invitations.
• Review attendance trends and class comparisons with interactive reports.
• Configure branding, check-in settings, membership plans, staff access, and athlete communications.
• Connect your own Stripe account for member billing while keeping gym funds and banking under your control.

Built for the daily rhythm of BJJ: show up, train hard, run the academy, and track the work.


## Version history (last 5 releases)

### 1.0.4 — 2026-08-22

New in 1.0.4:

• Message athletes at your gym privately—friendship is no longer required.
• Use the prominent Ask for a round action on Social, or send a round request from an existing private conversation.
• See gym-wide Mat Activity from athletes at your academy.
• Momentum standings now explain credited sessions, weekly goals, and the path to the next position more clearly.
• Improved notifications, privacy controls, blocking, legal-consent handling, and general reliability.

### 1.0.3 — 2026-08-21

Smart reminders make it easier to build an accurate training history.

• After you attend the same recurring class twice, GrappleOS can suggest adding it to Favorites so class reminders stay on.
• Choose “Not now” to quietly snooze the suggestion.
• Athletes can optionally enable Arrival check-in reminders in Profile → Notification settings.
• Arrival reminders use a low-power gym geofence and open Check-in when tapped. They never check you in automatically or store a location trail.
• Improved reminder controls, privacy explanations, and notification reliability.

### 1.0.2 — 2026-08-12

Competition history is easier to bring into GrappleOS and keep current.

• Paste a public Smoothcomp profile to preview and import events, divisions, matches, placements, and published results—no Smoothcomp password required.
• Sync again later without duplicating events or matches.
• GrappleOS now recognizes JJWL and IBJJF profile links and provides clear guided entry where those providers do not offer a public history feed.
• Athletes who also coach or manage a gym can switch to Staff view from a clear Profile header control.
• Continued navigation and profile polish throughout the athlete experience.

### 1.0.1 — 2026-08-12

GrappleOS has grown into a richer athlete and gym experience:

• Meet Mat Friends, share training activity, react and comment, and control what your public profile displays.
• Train independently with a private journal and tournament diary, or import public Smoothcomp competition history with one link.
• Join gym and platform challenges, earn lasting achievements, track progress, and celebrate milestones.
• Get gym announcements, favorite-class reminders, and improved check-in feedback.
• Enjoy Google sign-in, clearer onboarding, smoother navigation, refreshed profiles, and expanded staff attendance, reports, waivers, and gym tools.

### 1.0.0 — 2026-08-11
