# Electrolyte vs TachyMon

The clearest difference is rating: Electrolyte at 5.0 against TachyMon's 3.8. Electrolyte also leads on in-app purchases (none vs 2) and iOS requirement (13.0 vs 16.4). TachyMon's advantage is ratings volume (286 vs 2) and review sentiment (58% vs 40%). On price, ads and device support there is nothing between them.

Both are free to download. TachyMon sells 2 in-app purchases, starting at $2.99 per month. Electrolyte asks for nothing beyond the download.

Electrolyte holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: TachyMon has 286 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 40% of Electrolyte's written reviews are positive against 58% of TachyMon's, so the app with the better star average is not the one people write more warmly about.

Electrolyte ships an update every 7 months, TachyMon every 3 months. The most recent releases landed on September 21, 2026 and October 16, 2026 respectively.
