# Kingdemy vs Microelectronics

The clearest difference is update cadence: Microelectronics at every 3 months against Kingdemy's every 14 months. Kingdemy's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Kingdemy sells 4 one-off in-app purchases and Microelectronics sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Kingdemy ships an update every 14 months, Microelectronics every 3 months. The most recent releases landed on September 19, 2026 and September 17, 2026 respectively.
