# CSV File Viewer vs CSV Master

CSV File Viewer and CSV Master both sit at 3.8 stars, but that hides the real split: 90% of CSV File Viewer's written reviews are positive against 33% of CSV Master's. CSV File Viewer also leads on ads (none vs shown) and update cadence (every 8 days vs every 3 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. CSV File Viewer sells 6 in-app purchases, starting at $2.99 per month and CSV Master sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: CSV File Viewer has 20 ratings behind it against 3, so its average is the more settled of the two.
