Both are free to download. WL Analysis sells 1 one-off in-app purchase and CoachView Slowmo Video Player sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
CoachView Slowmo Video Player holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: CoachView Slowmo Video Player has 610 ratings behind it against 46, so its average is the more settled of the two. Written reviews complicate that: 62% of WL Analysis's written reviews are positive against 61% of CoachView Slowmo Video Player's, so the app with the better star average is not the one people write more warmly about.
WL Analysis ships an update every 6 weeks, CoachView Slowmo Video Player every 4 months. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
