# Margins vs Research Bites

The clearest difference is in-app purchases: Research Bites at none against Margins's 3. Research Bites also leads on iOS requirement (15.1 vs 17.0). Margins's advantage is ratings volume (20K vs 1) and chart position (#50 vs unranked). On price, rating, update cadence and ads there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.9 for Margins against 5.0 for Research Bites. That said, the two scores are not equally well evidenced: Margins has 20K ratings behind it against 1, so its average is the more settled of the two.

Margins ships an update every 4 days, Research Bites every 2 days. The most recent releases landed on November 10, 2026 and November 4, 2026 respectively.
