Verdict
The clearest difference is rating: Tzp at 5.0 against SecEMS's 3.8. SecEMS's advantage is ratings volume (17 vs 2) and iOS requirement (8.0 vs 11.0). On price, update cadence, ads and in-app purchases 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. SecEMS sells 4 in-app purchases, starting at $0.99 per month and Tzp sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Tzp holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: SecEMS has 17 ratings behind it against 2, so its average is the more settled of the two.
SecEMS ships an update every 2 months, Tzp monthly. The most recent releases landed on October 1, 2026 and October 4, 2026 respectively.
