# ICCR vs Bolus

The clearest difference is in-app purchases: ICCR at none against Bolus's 2. Bolus's advantage is update cadence (fortnightly vs every 33 months) and ratings volume (10 vs 2). On price, rating, ads and device support there is nothing between them.

Both are free to download. Bolus sells 2 in-app purchases, starting at $58.00 per month. ICCR asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for ICCR against 5.0 for Bolus. That said, the two scores are not equally well evidenced: Bolus has 10 ratings behind it against 2, so its average is the more settled of the two.

ICCR ships an update every 33 months, Bolus fortnightly. The most recent releases landed on October 29, 2026 and October 9, 2026 respectively.
