Running a bouldering competition shouldn't mean drowning in paper scorecards and spreadsheets. BoulderScoring is the competition management app built specifically for climbing gyms and comp organizers — so you can focus on the event, not the math. Set up in minutes. Create your comp, configure categories, assign boulders, and share a password with your climbers. That's it. No complicated setup, no IT required. Real-time scoring, live leaderboards. Scores update the moment they're entered. Climbers, coaches, and spectators can follow standings live on any device — no refreshing, no waiting. Self-entry or judge mode — your call. Let climbers log their own sends on their phones, or assign judges to boulders for formal competitions where accuracy matters. Both modes work together seamlessly. Flexible enough for many formats. Points-based scoring with tops, zones, and attempt penalties. Redpoint scoring with custom boulder values. Tops-only. Flash bonuses. Configure it to match your comp exactly. Built for real gyms. Separate categories by gender, age, and skill level. Assign different boulder sets to different divisions. Run team competitions alongside individual results. Export final standings when it's done. BoulderScoring is free to use. No subscriptions, no per-event fees — just a better way to run your comp.

Verdict

The call

The clearest difference is rating: Retro Flash at 4.7 against Boulder Scoring's 4.2. Retro Flash also leads on ratings volume (226 vs 6) and device support (3 vs 1). Boulder Scoring's advantage is in-app purchases (none vs 8) and review sentiment (100% vs 83%). On price, update cadence, ads and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Retro Flash holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Retro Flash has 226 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 83% of Retro Flash's written reviews are positive against 100% of Boulder Scoring's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Retro Flash ships an update every 3 weeks, Boulder Scoring every 2 weeks. The most recent releases landed on September 27, 2026 and September 11, 2026 respectively.
