# EVlog vs DoBuff

The clearest difference is rating: DoBuff at 4.8 against EVlog's 1.0. DoBuff also leads on ratings volume (39 vs 1) and review sentiment (100% vs 85%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. EVlog sells 1 one-off in-app purchase and DoBuff sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

DoBuff holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: DoBuff has 39 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 85% of EVlog's written reviews are positive against 100% of DoBuff's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on August 29, 2026 and September 5, 2026 respectively.
