# YI Home vs MathBell

The clearest difference is rating: YI Home at 4.3 against MathBell's 3.0. YI Home also leads on ratings volume (72K vs 1) and chart position (#157 vs unranked). MathBell's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 weeks). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. YI Home sells 10 in-app purchases, starting at $4.99 per month and MathBell sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

YI Home holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: YI Home has 72K ratings behind it against 1, so its average is the more settled of the two.

YI Home ships an update every 2 weeks, MathBell every 4 days. The most recent releases landed on November 12, 2026 and November 9, 2026 respectively.
