# Prisma Mobile vs DB

The clearest difference is rating: DB at 4.5 against Prisma Mobile's 1.0. DB also leads on ratings volume (37 vs 2). Prisma Mobile's advantage is in-app purchases (none vs 3) and update cadence (every 5 weeks vs every 5 months). On price, ads and device support there is nothing between them.

Both are free to download. DB sells 3 in-app purchases, starting at $3.99 per 7 days. Prisma Mobile asks for nothing beyond the download.

DB holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: DB has 37 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 18% of Prisma Mobile's written reviews are positive against 4% of DB's, so the app with the better star average is not the one people write more warmly about.

Prisma Mobile ships an update every 5 weeks, DB every 5 months. The most recent releases landed on October 8, 2026 and October 30, 2026 respectively.
