Verdict
The clearest difference is rating: Mathicon at 3.9 against Zero?'s 3.3. Mathicon also leads on update cadence (every 3 days vs every 3 months) and ratings volume (32 vs 4). Zero?'s advantage is in-app purchases (none vs 1). On price, review sentiment, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mathicon sells 1 one-off in-app purchase. Zero? asks for nothing beyond the download.
Mathicon holds the better App Store score, 3.9 against 3.3. That said, the two scores are not equally well evidenced: Mathicon has 32 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Zero?'s written reviews are positive against 94% of Mathicon's, so the app with the better star average is not the one people write more warmly about.
Zero? ships an update every 3 months, Mathicon every 3 days. The most recent releases landed on July 13, 2026 and June 9, 2026 respectively.
