# Code Viewer vs CSVReader

The clearest difference is rating: CSVReader at 4.6 against Code Viewer's 3.4. CSVReader also leads on review sentiment (60% vs 49%) and ratings volume (118 vs 18). Code Viewer's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Code Viewer sells 1 one-off in-app purchase and CSVReader sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CSVReader holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: CSVReader has 118 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 49% of Code Viewer's written reviews are positive against 60% of CSVReader's.

Code Viewer ships an update every 3 weeks, CSVReader every 2 months. The most recent releases landed on October 7, 2026 and October 1, 2026 respectively.
