# Bolt Out vs Slab

The clearest difference is update cadence: Slab at every 3 days against Bolt Out's every 2 months. Slab also leads on ratings volume (8 vs 1). Bolt Out's advantage is monetization model (ad-supported vs free with in-app purchases). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Bolt Out sells 1 one-off in-app purchase and Slab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Bolt Out against 5.0 for Slab. That said, the two scores are not equally well evidenced: Slab has 8 ratings behind it against 1, so its average is the more settled of the two.

Bolt Out ships an update every 2 months, Slab every 3 days. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
