Verdict

The call

The clearest difference is price: ÉTSMobile at Free against Touch Waves's $3.99. ÉTSMobile also leads on rating (4.6 vs 3.0) and update cadence (every 2 months vs every 5 months). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

ÉTSMobile is free to download; Touch Waves costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

ÉTSMobile holds the better App Store score, 4.6 against 3.0. Both are backed by a comparable volume of ratings — 2 and 5 respectively. Written reviews complicate that: 63% of Touch Waves's written reviews are positive against 58% of ÉTSMobile's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Touch Waves ships an update every 5 months, ÉTSMobile every 2 months. The most recent releases landed on September 29, 2026 and October 9, 2026 respectively.
