# MOBS vs Longbox

The clearest difference is rating: MOBS at 4.5 against Longbox's 4.0. MOBS also leads on in-app purchases (none vs 3) and ratings volume (13 vs 4). Longbox's advantage is review sentiment (100% vs 78%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Longbox sells 3 in-app purchases, starting at $1.99 per month. MOBS asks for nothing beyond the download.

MOBS holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 13 and 4 respectively. Written reviews complicate that: 78% of MOBS's written reviews are positive against 100% of Longbox's, so the app with the better star average is not the one people write more warmly about.

MOBS ships an update every 5 days, Longbox every 3 days. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
