Verdict
The clearest difference is review sentiment: Savior Heat at 80% against ECHO Water's 20%. Savior Heat also leads on iOS requirement (13.0 vs 15.1). ECHO Water's advantage is rating (4.6 vs 2.7) and update cadence (every 3 weeks vs every 15 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ECHO Water holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: ECHO Water has 137 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 80% of Savior Heat's written reviews are positive against 20% of ECHO Water's, so the app with the better star average is not the one people write more warmly about.
Savior Heat ships an update every 15 months, ECHO Water every 3 weeks. The most recent releases landed on October 7, 2026 and October 23, 2026 respectively.
