# ReaderView vs DoCube

The clearest difference is update cadence: ReaderView at every 3 days against DoCube's every 3 weeks. ReaderView also leads on ratings volume (66 vs 11). DoCube's advantage is review sentiment (100% vs 88%). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.5 for ReaderView against 4.6 for DoCube. That said, the two scores are not equally well evidenced: ReaderView has 66 ratings behind it against 11, so its average is the more settled of the two. Written reviews are what separate them: 88% of ReaderView's written reviews are positive against 100% of DoCube's.

ReaderView ships an update every 3 days, DoCube every 3 weeks. The most recent releases landed on September 21, 2026 and September 5, 2026 respectively.
