# TOXBASE vs MDU

The clearest difference is rating: MDU at 4.0 against TOXBASE's 1.0. MDU also leads on in-app purchases (none vs 1) and iOS requirement (12.2 vs 15.5). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. TOXBASE sells 1 one-off in-app purchase. MDU asks for nothing beyond the download.

MDU holds the better App Store score, 4.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 21% of TOXBASE's written reviews are positive against 17% of MDU's, so the app with the better star average is not the one people write more warmly about.

TOXBASE ships an update every 6 months, MDU every 3 months. The most recent releases landed on September 26, 2026 and September 13, 2026 respectively.
