# Graph vs ChartDay

The clearest difference is review sentiment: ChartDay at 100% against Graph's 30%. ChartDay also leads on rating (5.0 vs 2.9) and iOS requirement (16.2 vs 26.0). Graph's advantage is ratings volume (15 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

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

ChartDay holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: Graph has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 30% of Graph's written reviews are positive against 100% of ChartDay's.

Graph ships an update monthly, ChartDay every 3 weeks. The most recent releases landed on September 19, 2026 and June 1, 2026 respectively.
