# Vial vs Helix

The clearest difference is update cadence: Vial at every 3 days against Helix's weekly. Helix's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Vial ships an update every 3 days, Helix weekly. The most recent releases landed on October 6, 2026 and September 23, 2026 respectively.
