# Bolus vs Induction

The clearest difference is in-app purchases: Induction at none against Bolus's 2. Induction also leads on update cadence (every 5 days vs fortnightly). Bolus's advantage is ratings volume (10 vs 1) and iOS requirement (15.1 vs 18.0). 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. Induction asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Bolus against 5.0 for Induction. That said, the two scores are not equally well evidenced: Bolus has 10 ratings behind it against 1, so its average is the more settled of the two.

Bolus ships an update fortnightly, Induction every 5 days. The most recent releases landed on October 9, 2026 and October 25, 2026 respectively.
