# Thevenin vs Ohmie

The clearest difference is review sentiment: Thevenin at 100% against Ohmie's 57%. Thevenin also leads on ads (none vs shown) and iOS requirement (17.6 vs 26.2). Ohmie's advantage is rating (4.5 vs 4.2) and ratings volume (209 vs 10). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Thevenin sells 2 in-app purchases, starting at $4.99 per month and Ohmie sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Ohmie holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Ohmie has 209 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 100% of Thevenin's written reviews are positive against 57% of Ohmie's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 days. The most recent releases landed on October 17, 2026 and October 14, 2026 respectively.
