# RotX vs Ohmie

The clearest difference is review sentiment: RotX at 100% against Ohmie's 56%. RotX also leads on rating (5.0 vs 4.5) and ads (none vs shown). Ohmie's advantage is ratings volume (309 vs 3) and update cadence (every 3 days vs every 8 days). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. RotX sells 2 in-app purchases, starting at $1.99 per month and Ohmie sells 5 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

RotX holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Ohmie has 309 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of RotX's written reviews are positive against 56% of Ohmie's.

RotX ships an update every 8 days, Ohmie every 3 days. The most recent releases landed on October 17, 2026 and October 28, 2026 respectively.
