# Second Nature vs Low FODMAP System

The clearest difference is in-app purchases: Second Nature at none against Low FODMAP System's 10. Second Nature also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 months). Low FODMAP System's advantage is rating (4.8 vs 4.3). On price, ratings volume and device support there is nothing between them.

Both are free to download. Low FODMAP System sells 10 in-app purchases, starting at $4.49 per month. Second Nature asks for nothing beyond the download.

Low FODMAP System holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 57 and 79 respectively. Written reviews complicate that: 65% of Second Nature's written reviews are positive against 52% of Low FODMAP System's, so the app with the better star average is not the one people write more warmly about.

Second Nature ships an update every 3 days, Low FODMAP System every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
