# Insulin vs Bolus Guide

The clearest difference is rating: Insulin at 4.7 against Bolus Guide's 3.8. Bolus Guide's advantage is update cadence (every 5 days vs every 9 months) and review sentiment (60% vs 33%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Insulin holds the better App Store score, 4.7 against 3.8. Both are backed by a comparable volume of ratings — 3 and 12 respectively. Written reviews complicate that: 33% of Insulin's written reviews are positive against 60% of Bolus Guide's, so the app with the better star average is not the one people write more warmly about.

Insulin ships an update every 9 months, Bolus Guide every 5 days. The most recent releases landed on October 9, 2026 and October 1, 2026 respectively.
