# NAGI Step vs 倍速時計

The clearest difference is ads: 倍速時計 at none against NAGI Step's shown. NAGI Step's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. NAGI Step sells 4 in-app purchases, starting at $2.99 per month and 倍速時計 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
