# Fast vs ShotLog

The clearest difference is update cadence: ShotLog at every 10 days against Fast's every 2 months. Fast's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Fast ships an update every 2 months, ShotLog every 10 days. The most recent releases landed on November 13, 2026 and November 6, 2026 respectively.
