# tes vs ELMCheck

The clearest difference is rating: ELMCheck at 5.0 against tes's 4.3. ELMCheck also leads on review sentiment (100% vs 75%). tes's advantage is ratings volume (22 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. tes sells 8 in-app purchases, starting at $9.99 per year and ELMCheck sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ELMCheck holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: tes has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of tes's written reviews are positive against 100% of ELMCheck's.

tes ships an update every 3 weeks, ELMCheck every 2 weeks. Both last shipped on October 24, 2026.
