Also, the bland bare-bones keyboard display is disappointing. In marked contrast, the App’s manual videos show a nice color-enhanced emulated Ti-84 keyboard. The graphing functions appear to work well. Overall, this is an App that has much potential, but it needs more development. ### 1/5 — 这只是说明书！！！ *2018-05-30* 强调一下，这只是说明书！想买手机版计算器的朋友们请绕道。我就买错了，在此提醒大家一下。买错了还退不了款 ### 1/5 — Misleading *2018-04-03, version 1.5.2* I thought I was purchasing the calculator not the manual ### 1/5 — Make the fact that it’s a manual more clear *2018-03-29, version 1.5.2* It should be more clear that this is a manual I understand that it’s in the icon but not clear once you click on the app when you buy it I only understood that this was a manual until after I read someone else’s review which was after I purchased the app sadly $4.99 down the drain :( and I hope I can get a refund ### 1/5 — This isn’t even a calculator *2018-03-15, version 1.5.2* I paid $5 for a manual, foh ### 1/5 — I’m sure it helpful but it is misleading *2018-02-21, version 1.5.1* No calculator included... my fault for not reading the fine print but the reviews made it seem like it was a calculator as well. Don’t make the same mistake I did kids!😆 ### 1/5 — Intentionally Misleading fake positive reviews *2018-02-21, version 1.5.1* They make it seem as if it’s a calculator but it’s literally a $5 manual... most people assume it’s a manually inputted calculator. Even the reviews talk about how good the CALCULATOR is. good job putting out your own misleading reviews on your scam app. ### 3/5 — TI 84 Manual *2018-02-14, version 1.5.1* How do I request a refund? ### 1/5 — Don’t like it! *2018-02-12, version 1.5.1* I was trying to use this to help with my homework and I can’t get it to work. It won’t let me put a problem in. Very confusing to use. ## Most critical reviews (10 lowest-rated) ### 1/5 — Out of run,don’t buy it *2021-10-25, version 1.5.7* Out of run,don’t buy it ! ### 1/5 — Garbage *2020-10-12, version 1.5.7* Absolute waste of money it was a complete scam ### 1/5 — DO NOT BUY *2020-02-02, version 1.5.7* Extremely misleading and the creators know this. I was sitting in class trying to download a calculator for my college course. 5 dollars for information that I can easily google or look in my class notes for. DO NOT WASTE YOUR MONEY. SHAME ON THE CREATORS. ### 1/5 — Wouldn’t recommend this to anyone! *2019-05-07, version 1.5.7* This is by far the worst paid app I’ve come across! You can’t even press anything when you want to graph functions! It’s just pictures of how to enter them instead of actual help! ### 1/5 — Lies *2019-04-13, version 1.5.7* I thought this was a calc. It’s not. I feel played.... ### 1/5 — DO NOT BUY IF YOU ARE LOOKING FOR A CALCULATOR *2019-01-10, version 1.5.7* This app is not a calculator. It is a manual for a calculator. DONT FALL FOR THE TRICK ### 1/5 — I WANT MY MONEY BACK! *2018-11-05* I’ve written a nice email regarding your app costing $17 CAD, and doing absolutely nothing for helping in terms of your “APPS” button doesn’t function the same as the TI 84 calculator and your financial calculator seems to have some sort of bug to. Please refund my money! This is bull! ### 1/5 — TERRIBLE APP *2018-10-26, version 1.5.6* Nothing like the Ti-84 plus graphing calculator, missing so many options , I want my money back such a waste of money and all these graphing calculator apps don’t work at all!!!! ### 1/5 — Trash *2018-10-11, version 1.5.6* Isn’t even a real calculator and I can’t refund it ### 1/5 — Sneaky lying to get your money *2018-10-11, version 1.5.6* Basically, you’re paying $5 for something you can google search. They’re sneaky and make it look like an actual ti-84. Don’t waste your money on this useless purchase. There are students who need calculators, and you’ll get companies like this that take advantage of that. Shame on you. ## Most praised reviews (10 highest-rated) ### 5/5 — WARNING: this app is a manual *2019-01-25, version 1.5.7* This is a great calculator manual. 👍👍👍 ### 5/5 — My favorites *2018-10-28, version 1.5.6* After using this app, I can say that this application is the best way to make a friendship with graphing calculation.
