Literally. After my wife left me and took the kids, I was forced to live in dumpsters behind Bakersfield. But when I entered John Makous’s class and downloaded this app, I started a charity and became one of the riches people of all time. This app truly saved me. If you are in a similar situation, please download this app. ### 5/5 — This app makes me feel whole again. *2022-09-27, version 1.0* My life never felt whole, like there was something missing in it. As soon as I joined Johns physics class and downloaded this app, I finally figured out what I was missing. GraphModeling app. This specimen of an app solves depression, loneliness, and any other form of tragedy in your life. Thank you GraphModeling. ### 5/5 — This app is amazing *2021-12-06, version 1.0* This app is easily the best thing to happen in my life. Before I discovered this app, I was in a dark place in my life, I felt like I was losing it all. However, when I discovered this app, all my problems dissapeared. I found that everything became simpler and I began to appreciate the little things in life. I would highly recommend this app to anyone, even if you aren’t in a similar situation as me. ### 5/5 — this is epic *2020-11-19, version 1.0* Positivity ### 5/5 — I am nothing without Graph Modeling *2020-02-18, version 1.0* The wonders graph modeling has done for me is appalling. No longer are there days when I am forced to eat banana peels in my bathtub. No longer are there times when my foot acne stains my bed with its leaking pus. No longer do I have to use my T1-84 to unclog my toilet after a fat dump. Graph modeling does it all. Truly, this is the most handy-dandy app of all time. My wife left me for this app. My kids live with Graph Modeling on the weekends. But its all worth it. I never thought I would see the light of day after I lost my eyesight in a horrible ice skating accident in 2014. However, with Graph Modeling’s superior computing horse power, I regained my eyesight and even a third nipple. I don’t know where I would be without this hunk of a man, John Makous. Thank you for creating this app, John. Now I am free. ### 5/5 — My favorite app *2020-02-05, version 1.0* This is the only app I use! I go to sleep at night dreaming about this app! ### 5/5 — Work of Art *2019-10-22, version 1.0* This app truly inspires me to be the best person I can be. This app is the reason I get up in the morning. This app was probably created by Obama or someone super rich and super smart. This app is a beautiful work of art. This app makes me seem smarter and makes other people want to be my friend. ### 5/5 — Rahul *2019-10-21, version 1.0* This truly wonderful app has propelled to TikTok fame! A thousand thanks Dr. Makous! #Fyp #Foryoupage ### 5/5 — Cured my depression (not clickbait) *2019-08-27, version 1.0* I’ve been really depressed since my grandmother died causing my parents to divorce but thanks to this amazing app I’m able to put on a smile to hide the pain underneath. The amazing range of capabilities that this app has makes the sweet freeing release of death seem small in comparison. After all my friends left me I was extremely lonely but now thanks to this app people are practically lining up to be friends with me. Truly this app has changed my life. ### 5/5 — WoRtH iTtTt *2019-01-10, version 1.0* Happiness? Fulfilled. Goals? Achieved. Graphs? Modeled. Wig? Snatched. Hotel? Trivago. ## Frequently asked questions about GraphModeling ### What does GraphModeling do? This app enables science students to manually fit a curve to experimental data.
