# ChartDay vs Graph Maker

The clearest difference is review sentiment: ChartDay at 100% against Graph Maker's 31%. ChartDay also leads on rating (5.0 vs 3.7) and ads (none vs shown). Graph Maker's advantage is ratings volume (15 vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

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

ChartDay holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: Graph Maker has 15 ratings behind it against 3, so its average is the more settled of the two.
