# Electronic Circuits Calculator vs Tenio

The clearest difference is ads: Tenio at none against Electronic Circuits Calculator's shown. Tenio also leads on monetization model (free vs ad-supported). Electronic Circuits Calculator's advantage is update cadence (every 2 months vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Electronic Circuits Calculator ships an update every 2 months, Tenio every 4 months. The most recent releases landed on October 19, 2026 and October 24, 2026 respectively.
