# Case Files vs ECG Notes

The clearest difference is review sentiment: Case Files at 100% against ECG Notes's 50%. Case Files also leads on ads (none vs shown) and rating (5.0 vs 4.7). ECG Notes's advantage is update cadence (every 3 months vs every 12 months) and ratings volume (12 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Case Files sells 5 in-app purchases, starting at $9.99 per 7 days and ECG Notes sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Case Files holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ECG Notes has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Case Files's written reviews are positive against 50% of ECG Notes's.

Case Files ships an update every 12 months, ECG Notes every 3 months. The most recent releases landed on October 19, 2026 and October 21, 2026 respectively.
