"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. Free plan: up to 30 Link2Mat items and 120 clips. You can keep using the app within these limits without a subscription. Optional Link2Mat Plan: unlimited items and clips and other Pro benefits. If you start a subscription, you get a 30-day free trial, then JPY 200/month (auto-renewal). The trial begins when you subscribe—not at install.

Importing a list package on another device also ignores removed groups from older export files. ### 2.4.2 — 2026-05-24 - Clips & Shorts: pin individual clips alongside library items (shared pin limit). - Pin or unpin from clip detail. In Shorts & Clips, pinned clips stay at the top (like Library). In each item’s clip list, you can toggle “Pins first.” - Library pin guide lists pinned clips too; open a clip or unpin from the guide. - Lists: when manually reordering a list, sort all items by title in one tap. - Photo library stills: imported photos get titles from capture date/time and approximate area when location is embedded in the photo; list thumbnails are saved in the app. On item detail, photos show View instead of Play. - Tag dictionary: added knee twist (setup). ### 2.3.0 — 2026-05-05 - Lists (v1): you can group saved items into your own lists and review them more smoothly by context. - From Today’s retention study, opening item detail now keeps a stable return path to the same retention list. - Tag dictionary updates include Tomoe Nage, Yoko Tomoe Nage, and Keymaster, with alias/search coverage expanded. - Thumbnail cache touches are throttled for frequent list rendering, reducing repeated disk writes and keeping long-list scrolling smoother. - Custom images remain prioritized. If a custom image cannot be used, Link2Mat can fall back to preview retrieval from the URL (including Instagram links). ### 1.2.3 — 2026-03-21 Stability improvements and minor fixes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
