Verdict

The call

The clearest difference is price: CHMate at Free against eBooks Pro's $4.99. eBooks Pro's advantage is rating (4.8 vs 3.9) and update cadence (every 8 days vs every 2 weeks). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

CHMate is free to download; eBooks Pro costs $4.99 up front. CHMate sells 1 one-off in-app purchase and eBooks Pro sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

eBooks Pro holds the better App Store score, 4.8 against 3.9. Both are backed by a comparable volume of ratings — 20 and 8 respectively. Written reviews complicate that: 55% of CHMate's written reviews are positive against 50% of eBooks Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CHMate ships an update every 2 weeks, eBooks Pro every 8 days. The most recent releases landed on November 6, 2026 and November 12, 2026 respectively.
