# idoki vs FandomChart

The clearest difference is rating: idoki at 4.2 against FandomChart's 1.0. idoki also leads on update cadence (every 4 days vs monthly) and ratings volume (6 vs 2). FandomChart's advantage is review sentiment (100% vs 80%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. idoki sells 10 in-app purchases, starting at $2.99 per month and FandomChart sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

idoki holds the better App Store score, 4.2 against 1.0. Both are backed by a comparable volume of ratings — 6 and 2 respectively. Written reviews complicate that: 80% of idoki's written reviews are positive against 100% of FandomChart's, so the app with the better star average is not the one people write more warmly about.

idoki ships an update every 4 days, FandomChart monthly. The most recent releases landed on September 21, 2026 and June 3, 2026 respectively.
