Verdict

The call

The clearest difference is review sentiment: Index at 100% against RemNote's 74%. Index also leads on rating (5.0 vs 4.8). RemNote's advantage is ratings volume (1.7K vs 1) and update cadence (every 3 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. RemNote sells 8 in-app purchases, starting at $14.99 per month and Index sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Index holds the better App Store score, 5.0 against 4.8.
