# Traffic Flow vs Overline

The clearest difference is ads: Overline at none against Traffic Flow's shown. Traffic Flow's advantage is update cadence (every 4 days vs every 5 weeks) and chart position (#120 vs unranked). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Traffic Flow sells 18 one-off in-app purchases and Overline sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Traffic Flow ships an update every 4 days, Overline every 5 weeks. Both last shipped on October 24, 2026.
