Verdict

The call

The clearest difference is ads: HeartSnap at none against CardiaLink's shown. CardiaLink's advantage is rating (4.7 vs 4.5). On price, review sentiment, ratings volume and update cadence 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. CardiaLink sells 2 in-app purchases, starting at $9.99 per 7 days and HeartSnap sells 2 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

CardiaLink holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 8.2K and 4.8K respectively. Written reviews complicate that: 18% of CardiaLink's written reviews are positive against 22% of HeartSnap's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CardiaLink ships an update every 3 weeks, HeartSnap fortnightly. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
