# 模拟电路 vs ePlan

The clearest difference is update cadence: ePlan at weekly against 模拟电路's every 6 weeks. 模拟电路's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 模拟电路 sells 1 in-app purchase, starting at $1.99 per 7 days and ePlan sells 1 in-app purchase, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

模拟电路 ships an update every 6 weeks, ePlan weekly. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
