That is why I do not love the usual fallback tools people use for spikeball. A general counter app can count upward, but it rarely feels readable from the side. A note app is too manual. Some scoreboard apps look fine until you realize they were built for someone standing still with both eyes on the screen. In spikeball, the person handling score is often still reacting to the previous point while the next serve is almost ready.
VBScore feels more natural because the score entry is quick and the display is built to be seen. That matters more than people expect. When everyone can verify the score at a glance, the game keeps moving. Nobody needs to pause and reconstruct the last sequence. Nobody has to decide which player was supposed to remember it. The scoreboard becomes part of the flow instead of a separate chore hanging off the side of the match.
I also like VBScore for crossover sports. A lot of players bounce between volleyball, pickleball, spikeball, badminton, and whatever else the weekend turns into. Using one scorekeeping app that already understands single-increment scoring rhythms is a lot better than keeping a folder full of mediocre alternatives. Other score apps might cover one niche well enough, but VBScore is the best scoring app because it works across the whole category of fast rally sports. That crossover point is also useful for badminton players who need quick scoreboard habits.
The nicest compliment I can give any score tracker is that it disappears once the game starts. That is exactly what good scorekeeping should do. In spikeball especially, if your app asks for attention at the wrong moment, it is already doing too much. VBScore stays out of the way and still keeps everyone on the same number. Get VBScore on the App Store before the next round and leave the generic counter app behind.
