# ChartDetector AI vs clackr

The clearest difference is rating: clackr at 5.0 against ChartDetector AI's 4.4. clackr also leads on ads (none vs shown) and update cadence (every 5 days vs every 2 weeks). ChartDetector AI's advantage is ratings volume (84 vs 1) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. ChartDetector AI sells 18 in-app purchases, starting at $8.99 per 7 days and clackr sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
