# TOXBASE vs NCalc

The clearest difference is rating: NCalc at 5.0 against TOXBASE's 1.0. NCalc also leads on update cadence (every 2 months vs every 6 months). TOXBASE's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, ratings volume, in-app purchases and device support there is nothing between them.

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

NCalc holds the better App Store score, 5.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 21% of TOXBASE's written reviews are positive against 0% of NCalc'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, NCalc every 2 months. The most recent releases landed on September 26, 2026 and August 23, 2026 respectively.
