Verdict
The clearest difference is in-app purchases: Supersonics Plus at none against Mathseeds's 4. Supersonics Plus also leads on review sentiment (80% vs 46%). Mathseeds's advantage is rating (4.6 vs 4.3) and ratings volume (255 vs 21). On price, update cadence, ads and monetization model 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. Mathseeds sells 4 in-app purchases, starting at $6.99 per month. Supersonics Plus asks for nothing beyond the download.
Mathseeds holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Mathseeds has 255 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 80% of Supersonics Plus's written reviews are positive against 46% of Mathseeds's, so the app with the better star average is not the one people write more warmly about.
Supersonics Plus ships an update every 3 months, Mathseeds every 2 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
