# 珍时 vs EVlog

The clearest difference is iOS requirement: 珍时 at 11.0 against EVlog's 16.2. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 珍时 sells 15 one-off in-app purchases and EVlog sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

珍时 ships an update fortnightly, EVlog weekly. The most recent releases landed on September 10, 2026 and August 29, 2026 respectively.
