Verdict
The clearest difference is rating: Electrolyte at 5.0 against KidneyDiet's 4.4. Electrolyte also leads on in-app purchases (none vs 2) and iOS requirement (13.0 vs 15.1). KidneyDiet's advantage is ratings volume (311 vs 2) and review sentiment (63% vs 40%). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. KidneyDiet sells 2 in-app purchases, starting at $7.99 per month. Electrolyte asks for nothing beyond the download.
Electrolyte holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: KidneyDiet has 311 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of KidneyDiet's written reviews are positive against 40% of Electrolyte's, so the app with the better star average is not the one people write more warmly about.
KidneyDiet ships an update every 3 months, Electrolyte every 7 months. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
