# Sauna Log vs Cold Plunge & Sauna Timer

Sauna Log and Cold Plunge & Sauna Timer are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Sauna Log sells 1 one-off in-app purchase and Cold Plunge & Sauna Timer sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
