# Spark vs Vice Locker

The clearest difference is rating: Spark at 5.0 against Vice Locker's 4.6. Spark also leads on update cadence (every 2 days vs every 9 days). Vice Locker's advantage is ratings volume (11 vs 2) and review sentiment (75% vs 67%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spark sells 3 in-app purchases, starting at $0.99 per month and Vice Locker sells 4 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Spark holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Vice Locker has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Spark's written reviews are positive against 75% of Vice Locker's, so the app with the better star average is not the one people write more warmly about.

Spark ships an update every 2 days, Vice Locker every 9 days. The most recent releases landed on November 5, 2026 and October 30, 2026 respectively.
