This app quickly creates graphs from simple input. Works with line, bar, and pie charts. We've also implemented a new combo chart with lines and bars. Combining a monthly bar chart with a cumulative line chart for each month makes the information much easier to understand. It's a bit quirky as it instantly draws graphs from input data. Please check the summary below. ・Data Values No strict input limits, but for a neat layout, keep characters short. Adjust units to shorten characters (e.g., [Unit: 1,000 yen]). ・Data Labels: Adjusted for the longest notation '20231101.' To minimize data label characters, use '23/11/01' or '11/1' as labels, and include '2023-' in the title. Labels with 3 or fewer characters display horizontally. ・Pie Charts If input totals 100, it's % distribution on the chart. If not, it auto-calculates percentages. Charts created with this app can be used freely for both commercial and non-commercial purposes.

Verdict
The clearest difference is in-app purchases: Dival at none against Graph Maker's 1. Graph Maker's advantage is update cadence (every 2 weeks vs every 5 weeks) and iOS requirement (15.5 vs 18.5). On price, ads and device support there is nothing between them.
