# Arc vs 시그널픽

The clearest difference is ads: 시그널픽 at none against Arc's shown. Arc's advantage is update cadence (every 2 days vs every 3 weeks) and iOS requirement (13.0 vs 18.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Arc ships an update every 2 days, 시그널픽 every 3 weeks. The most recent releases landed on August 24, 2026 and September 21, 2026 respectively.
