# TrueDot vs 加一

The clearest difference is price: 加一 at Free against TrueDot's $1.99. 加一 also leads on rating (5.0 vs 3.8) and review sentiment (100% vs 68%). TrueDot's advantage is ratings volume (5 vs 1). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

加一 is free to download; TrueDot costs $1.99 up front. TrueDot sells 1 one-off in-app purchase and 加一 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

加一 holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: TrueDot has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 68% of TrueDot's written reviews are positive against 100% of 加一's.

TrueDot ships an update every 6 days, 加一 weekly. The most recent releases landed on November 7, 2026 and November 4, 2026 respectively.
