# No Trace vs 傾到夜深

The clearest difference is ads: No Trace at none against 傾到夜深's shown. No Trace also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. No Trace sells 1 one-off in-app purchase and 傾到夜深 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

No Trace ships an update every 11 days, 傾到夜深 every 2 weeks. The most recent releases landed on September 21, 2026 and September 1, 2026 respectively.
