Practice photos, downloads, and web saves scatter across apps. Link2Mat unifies them: tags, clips, search, lists by theme, and retention study for when to revisit.
"buddy" for your jiu-jitsu learning
Jiu-jitsu is full of techniques: how you relate to your opponent, recovering from bad positions, counters, and choosing among many options—often in a split second. There is real joy when your body just moves. When things go wrong or you get tapped, asking your coach or teammates is still the best answer, but many of us also watch instruction and technique videos.
YouTube and social networks overflow with technique demos and lessons: "That's what hit me in rolling—how do I defend it?" "This might suit me—I want to try it next time."
Practice and match photos and videos, instructionals saved on your device, and links from the web add up—often scattered across your camera roll and different apps, and harder to see the whole picture as the pile grows.
We wanted one place for the videos and links you actually use—with tags and search, a way to see what you revisit, and pins to keep what you're focusing on at the top. That's why we built this app.
You can also organize saved items into lists to revisit them by theme or context. Removing an item from a list does not remove it from your library.
When you want a technique to really stick—not just saved—optional retention study suggests times to revisit, around when a quick refresher helps most. Open "Today's retention study" from the Library tab; morning reminders are optional.
Videos and photos in your library—including practice recordings—are added from the add screen via From Photos → Choose from library (no URL needed). Instructionals you save from a subscription service live in the same library as YouTube and social links, with the same tags, time-based clips, pins, and search.
For web videos (YouTube, Instagram, TikTok, Threads, and more), use Share in another app and pick "Link2Mat"—the add screen opens with the URL ready to analyze and save. You can also paste a URL or add from inside the app.
For full-day event videos on YouTube and long videos in your photo library, add clips at the start times you care about and open them right there.
Depending on the site, the app pulls in a title and description; you can edit or enter your own. From that text, the app suggests matching tags—and you can always pick tags manually.
Tags for BJJ vocabulary are grouped as position, scenario, setup, action, submission, and source. There are about 400; we take requests for additions and keep updating. Tap the "?" button to look up a term you don't know. Tags have aliases too, so you can search your saved videos and clips by tag or alternate name.
Nothing replaces sparring at the gym, your coach's lessons, or training with
teammates. We hope this app can help a little with preparation and conversations
around your training.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
- Fix: exporting a list no longer includes Quick Tag groups you removed. Importing a list package on another device also ignores removed groups from older export files.
