# TTReader vs G

The clearest difference is review sentiment: TTReader at 100% against G's 13%. TTReader also leads on update cadence (every 3 weeks vs every 11 months). G's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. TTReader sells 1 in-app purchase, starting at $1.99 per month and G sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

TTReader ships an update every 3 weeks, G every 11 months. The most recent releases landed on October 13, 2026 and October 6, 2026 respectively.
