Verdict

The call

The clearest difference is ads: TK at none against E's shown. TK also leads on rating (4.2 vs 4.0) and monetization model (free vs ad-supported). E's advantage is review sentiment (96% vs 81%) and update cadence (every 3 weeks vs every 6 weeks). On price and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

TK holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: TK has 21 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 81% of TK's written reviews are positive against 96% of E's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TK ships an update every 6 weeks, E every 3 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
