# ZT vs SimPulse

The clearest difference is ads: ZT at none against SimPulse's shown. SimPulse's advantage is update cadence (every 4 days vs weekly) and iOS requirement (13.0 vs 16.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. ZT sells 3 in-app purchases, starting at $1.99 per month and SimPulse sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ZT ships an update weekly, SimPulse every 4 days. The most recent releases landed on September 20, 2026 and September 10, 2026 respectively.
