It is superb. If I could ask for one new feature it would be the ability to write custom functions (as it looks like the developer is not making updates). I cannot give this higher praise than 10 plus years of use. ### 4/5 — No *2023-08-21* 自然対数と絶対値使えないのはやばい ### 4/5 — Excellent Application *2022-09-24, version 3.3.3* This application has helped with numerous homework assignments and has always provided the needed help! ### 5/5 — More than just graphing *2021-12-27, version 3.3.3* This app is my go to calculator for doing any calculations more complex than simple two number operations. Being able to group operations with parentheses, replay calculations, and edit them is super useful. ### 5/5 — It’s cool app. *2020-06-07, version 3.3.3* I strongly recommend this for graphing math equations. If I add something, please do graph partial differential equations ### 5/5 — Best *2020-05-15, version 3.3.3* So good ### 5/5 — The best calculator app *2020-01-10* Logs of the calculations results are so good for me. And I enjoy Graphing and it helps my study. Thank you so much!!!! ### 5/5 — All you need *2019-11-15, version 3.3.3* This is my go to calculator ### 5/5 — Even entertaining *2019-01-16, version 3.3.3* Very nice. Hope updates can allow the user to set the resolution. It may sometimes slow rendering, but occasionally one needs very high resolution. ### 5/5 — Awesome *2018-10-09, version 3.3.3* It’s a fantastic tool in my tutoring business. It enabled me to save the graphs, and send them to my students via text or email. ## Frequently asked questions about Good Grapher Pro ### What does Good Grapher Pro do?
