OpenScout helps you follow your VEX Robotics team through an entire tournament. OpenScout is an independent app from RoboSTEM Foundation, Inc., a 501(c)(3) nonprofit. It is not affiliated with, endorsed by, or sponsored by VEX Robotics, Innovation First International, or the Global Robotics & Science Foundation. Competition data comes from public event and team information on events.vex.com. FOLLOW YOUR TEAM Set your team number once. Home shows their next match, current ranking, and skills scores, and you arrange it from blocks for the events and teams you follow. SEARCH ACROSS VEX Explore searches across the entire program instead of just the page you're viewing. It understands common terms like sig, states, champs, and worlds. Search a full team number to see the events that team has competed at. FOLLOW A LIVE EVENT Open an event to see rankings, match results, elimination brackets, division standings, skills rankings, awards, and the venue agenda. Results update as the event runs. If a match has video, you can watch it inside OpenScout. Turn on predictions to see the win chances for each unplayed match, from OpenScout Score. SCOUT TEAMS Compare teams side by side, take match notes, build a picklist, work through alliance selection, and follow the bracket. Export an event to CSV, or save it to read offline. Make a Cloud team with your scouting group, and everyone's favorites, notes, and picklists stay in sync. TOURNAMENT MODE A single screen for the event you're attending. See your next match, which field you're on, and your current standing without digging through event pages. WORLD SKILLS STANDINGS View full-season World Skills rankings across every supported program and grade level. FIELD AND TIMER TOOLS Use the built-in match timer, score calculator, and whiteboard for practice and strategy. NOTIFICATIONS AND LIVE ACTIVITIES Get match results for the teams you favorite, and follow your team's matches on the Lock Screen and in the Dynamic Island. TRANSLATION Event and team names appear in the language entered by the event organizer. OpenScout can translate them automatically or whenever you request it. ACCOUNT OPTIONAL You don't need an account to use OpenScout. Signing in with Apple, Google, or Discord lets you sync your followed team, favorites, notes, and picklists across devices, and join Cloud teams. You can delete your account directly inside the app at any time. FREE, NO ADS, NO TRACKING OpenScout is free. There are no ads, no subscription, no third-party analytics, and no tracking across other apps and websites.

Verdict

The call

The clearest difference is in-app purchases: OpenScout at none against BuildCores's 10. OpenScout also leads on rating (4.9 vs 4.7) and update cadence (every 3 weeks vs every 6 weeks). BuildCores's advantage is ratings volume (2.1K vs 83) and iOS requirement (16.4 vs 18.0). On price, ads and device support there is nothing between them.
