# CalziAI vs Walking Tracker

The clearest difference is update cadence: CalziAI at every 10 days against Walking Tracker's every 3 weeks. Walking Tracker's advantage is iOS requirement (15.6 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. CalziAI sells 2 in-app purchases, starting at $14.99 per month and Walking Tracker sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
