Keep up the great work! (4Q2019 update) This is STILL *the* calculator app that beats out all others. I wish schools would standardize on this app. (1Q2022 update) Still the best! ### 5/5 — A great calculator app! *2026-01-27, version 3.4* I’ve been using this app for years. Great to have a graphing calculator in my pocket that works like the one I’m used to! I really appreciate the updates to support the new iOS. Happy to see that the author is still keeping it up to date. Edit: now it’s 2026, and he’s still keeping it updated! ### 5/5 — Great scientific calculator with really helpful graphing features *2026-01-21, version 3.4* Nice scientific calculator with great graphing capabilities, eliminating having to carry a separate calculator around ### 5/5 — Best calculator *2025-12-29, version 3.4* A must purchase. ### 5/5 — A nice little calculator for a great price *2025-12-27, version 3.4* Functions just like the familiar TI83 handheld including stat regression graphs. Can’t buy handheld TI 83 for this price. Free updates to boot. Free programs do not compete well with this app. ### 5/5 — Love *2025-12-18, version 3.4* I truly love this calculator. Got me through calculus one and two. ### 5/5 — Fantastic *2025-12-14, version 3.4* Really great calculator! Makes this mathematician happy! ### 5/5 — Great! *2025-12-12, version 3.4* Fantastic scientific calculator. Did everything I needed for my college level course and was extremely helpful to me with all the useful features and great design. ### 5/5 — Fantastic *2025-12-11, version 3.4* I’ve been looking to buy a calculator for graduate studies, this ticks all the boxes and works brilliantly! The updated version continues to improve on an already great product. Updating my review in light of the recent update: fantastic as ever! ### 5/5 — love this app *2025-12-08, version 3.4* It's the best calculator app I've found. Full featured and stable. The history and value recall feature (with up arrow) is great. ### 5/5 — Great Calculator App *2025-12-08, version 3.4* Love how it simulates the actual calculator. Even better are the graphics! ### 5/5 — Great *2025-12-07, version 3.4* All good - use it almost daily ### 5/5 — Worth the money *2025-12-05, version 3.4* I don’t know how much this app costs these days, but I would say pay it. This calculator has never failed me. Basically as good as desmos (for my uses) and simultaneously teaches you how to use a range of other physical scientific calculators which is a valuable skill. Math students of all (if not most) disciplines can find value (lol) in this calculator! ### 5/5 — The best call app! *2025-12-02, version 3.4* 2025, still awesome! Awesome - I use this app every day, all throughout the day. Nothing fancy, just machining and wood working, but I find I like this better than even dedicated apps for those functions. ### 5/5 — Works great. No ads. Leaves me to do my business in peace *2025-12-02, version 3.4* Yeah ### 5/5 — The Best Calculator *2025-12-02, version 3.4* This app saved me throughout high school and college math classes. It’s like having a TI84 in my pocket at all times. If you need a calculator, this is the app to get ### 5/5 — Graphncalc83 beats TI-84CE *2025-12-01, version 3.4* Best $0.99 ever spent! Even better features than TI has. Especially the graph and intersect features. No longer need to ‘enter, enter, enter’ which is so anti-pedagogical and ludicrous. Graphncalc83 just lets you easily find the exact point of intersection with one step. ### 5/5 — Awesome job I’ll *2025-11-30, version 3.4* I mmm used to carry my phone and a ti graphing calculator. Now I do not have to because the app is just as good as my graphing calculator !!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Horrible *2026-03-16, version 3.4* I hate math ### 1/5 — Don't bother *2016-12-12, version 1.6* Don't waste your $10.00. Not accurate at all.... ### 3/5 — Just got it… *2026-01-19, version 3.4* & I’m very annoyed that buttons will occasionally cover other buttons & will Not allow The offensive buttons to be moved ( !!! ) also; is there a pdf instructions manual that goes along with it ? ### 3/5 — 非常好的计算器 *2025-01-11* 非常好的计算器，如果支持中文帮助就好了！ ### 3/5 — Loved *2018-09-11, version 2.4* I have had this app since 2014. I bought it because the stats class I was in needed a specific function on a graphing calculator but I didn’t want to buy a brand new calculator. This has been my go-to calculator since. The only issue I have and it’s more pet peeve than anything, is that when you calculate a number and it won’t be a whole number the answer comes out as a fraction and then you have to punch in a few numbers to get a decimal. It’s annoying but other than that the calculator works just like a normal one for less money. ### 4/5 — Very good program *2024-08-05, version 3.2* For work and school ### 4/5 — nice calculator *2024-04-21, version 3.2* Just what I was looking for... I'm still learning but its the same as TI calculator, useful to do quick math and graph ### 4/5 — One thing *2021-10-31, version 2.8* Very easy to navigate I love using this for class, but when I have to calculate z and t scores sometimes it doesn’t refresh from the last when I press enter and I don’t catch it right away, you have to toggle to the data option to refresh it sometimes and I wish it would auto update when you enter data so there isn’t a risk off getting inaccurate scores from zs and ts exc that aren’t updated right away when you enter data ### 4/5 — Great! *2020-11-18* I haven’t had a chance to evaluate the whole app yet (therefore only 4 stars—sorry!) but it seems to function so much like the ti calculators that if someone needs to switch between this and one of ti‘s graphing calcs, it wouldn’t result in much getting used to at all. That is a HUGE plus. Students can practice with this App and then be better prepared when they are limited to an actual calculator for school or taking the SAT or some other testing purposes. I find it absolutely excellent that students can have access to a calculator like this without having to pay over $100 for an insanely cost prohibitive calculator that is only really worth about $15-$20, if that. After 20 years in math education, I could say so much about that racket but will refrain. ### 4/5 — Awesome++ *2020-09-13* I have been looking for a truly powerful calculator for a long time. I've tried variations of the HP top of the line and several were very nice but as I said in one of the other reviews that calculator emulators are great for what they are but the idea is to serve your needs. If a calculator still retains all of the disadvantages of the original then it is not an advancement. This calculator not only provides all the capabilities of the HP that inspired it but also eliminates many of the physical calculator's cons. Ever had a calculator that did everything you needed and more but required a book and a lot of memory work to do any of the sophisticated things? This one does not have that drawback. There is context based help available at the touch of a button. Now you can actually use the full power of the calculator without it becoming a research project. To me, that essentially made the more advanced the calculator the less useful it became. Not so here. I applaud the developer. We don't need exact replicas of calculators, we need something to do a job with the least effort on our part. This is a giant step in that direction. On top of that, the developer continues to add additional enhancements without resorting to “forever pay”. This is truly a rare gem. Calculators are not sacred but my time is. Get this. You won't regret it. Now I can get on with my work! ## Most praised reviews (10 highest-rated) ### 5/5 — Reliable *2026-08-11, version 3.4* I’ve had this calculator for 10 years now, since the start of high school.

I'm a high school math teacher. It is really wonderful to have an app that works like the calculator that I regularly use! I like it so much I promoted it on my math website! ### 5/5 — Best Calc for iOS *2026-04-09, version 3.4* I used a TI-83 in college (engineering) back in the 90’s and this is the perfect digital calculator I’ve found. Free updates with it are great.

I wish schools would standardize on this app. (1Q2026 update) Still the best! ### 5/5 — Love this! *2026-02-19, version 3.4* Very practical for my everyday use. Quite often I use the stats function to determine regression equations for grains vs velocity data. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
