Verdict

The call

The clearest difference is review sentiment: POTSie at 92% against Electrolyte's 40%. POTSie also leads on update cadence (weekly vs every 7 months) and ratings volume (54 vs 2). Electrolyte's advantage is in-app purchases (none vs 4) and rating (5.0 vs 4.8). On price, ads and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. POTSie sells 3 in-app purchases, starting at $2.99 per month. Electrolyte asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Electrolyte holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: POTSie has 54 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 92% of POTSie's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Electrolyte ships an update every 7 months, POTSie weekly. The most recent releases landed on October 8, 2026 and October 21, 2026 respectively.
