# Kortext vs Margins

The clearest difference is review sentiment: Margins at 95% against Kortext's 17%. Margins also leads on rating (4.9 vs 3.9) and update cadence (every 4 days vs every 2 months). Kortext's advantage is in-app purchases (none vs 3). On price, ads, chart position and device support there is nothing between them.

Both are free to download. Margins sells 3 in-app purchases, starting at $5.99 per month. Kortext asks for nothing beyond the download.

Margins holds the better App Store score, 4.9 against 3.9. That said, the two scores are not equally well evidenced: Margins has 20K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews point the same way: 17% of Kortext's written reviews are positive against 95% of Margins's.

Kortext ships an update every 2 months, Margins every 4 days. Both last shipped on October 24, 2026.
