Verdict

The call

The clearest difference is rating: VidTimer at 4.7 against JAWKU's 4.0. VidTimer also leads on update cadence (every 10 days vs every 2 months). JAWKU's advantage is in-app purchases (none vs 3) and ratings volume (244 vs 44). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

VidTimer holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: JAWKU has 244 ratings behind it against 44, so its average is the more settled of the two. Written reviews complicate that: 68% of JAWKU's written reviews are positive against 67% of VidTimer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

JAWKU ships an update every 2 months, VidTimer every 10 days. The most recent releases landed on September 30, 2026 and September 22, 2026 respectively.
