# Flat Speedometer vs Velocity Pro

The clearest difference is update cadence: Velocity Pro at every 2 weeks against Flat Speedometer's every 5 months. Flat Speedometer's advantage is device support (4 vs 2) and iOS requirement (9.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Flat Speedometer sells 2 one-off in-app purchases and Velocity Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Flat Speedometer ships an update every 5 months, Velocity Pro every 2 weeks. The most recent releases landed on June 3, 2026 and September 8, 2026 respectively.
