# Tick Sync vs TrueNTP

The clearest difference is ads: Tick Sync at none against TrueNTP's shown. TrueNTP's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Tick Sync sells 1 in-app purchase, starting at $1.99 per year and TrueNTP sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
