Verdict
The clearest difference is rating: WriteTex at 5.0 against MathNotes's 4.5. MathNotes's advantage is update cadence (every 4 days vs every 10 days) and ratings volume (8 vs 1). On price, ads, in-app purchases 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. WriteTex sells 3 in-app purchases, starting at $3.99 per month and MathNotes sells 8 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
WriteTex holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: MathNotes has 8 ratings behind it against 1, so its average is the more settled of the two.
WriteTex ships an update every 10 days, MathNotes every 4 days. The most recent releases landed on September 24, 2026 and October 8, 2026 respectively.
