Does the job. Fills a void that Apple has created on the iPad.

This calculator does all of the functions I need to do on a daily basis. The calculator theme colors can be changed to display any number of visually appealing themes. This calculator also has a number of other settings that can be changed to get your own desired look. I had a small issue/suggestion with Omega Calculator so I emailed the developer. The developer responded to my email very quickly. My thanks to the developer for a good looking calculator that works well and has no ads. Job well done! ### 5/5 — The best standard calculator in the App Store *2020-11-24, version 1.2.0* This is the best standard calculator in the App Store. The idea of this app was certainly inspired by mine “Calculator Omega” that is also available on the App Store, but this developer managed to do a very far better job than me, offering a completely free and fully functioning calculator, with plenty of colorful themes and text formatting options. I admit my defeat, I have no problem with that. I wish the best for this app, so that all the users with iPadOS will no longer have to buy apps or pay subscriptions. ### 5/5 — The Best Of The Best *2020-11-13, version 1.1.0* The Omega Calculator is 100%, the VERY BEST calculator I have EVER used. Beautiful and Fully Functional upon download...no developer tricks, no ads, no ridiculous fee’s. I have tried many of the Calculators available in the Apple App store, most have performed somewhere between fair and good, with annoying problems that could be alleviated ONLY by paying to have the annoyances removed. Also, I had a general iPad display issue that was on my end (in my personal iPad settings) and the developer even solved that iPad issue for me via eMail. Calculator Bliss is here, Omega Calculator for the win ! ### 5/5 — Great calculator *2020-08-30, version 1.0.0* This is the coolest calculator ever. Very cool colors and graphics. Does everything I need. ## Most critical reviews (10 lowest-rated) ### 1/5 — Stop trying to make me buy the pro version *2023-09-17, version 2.2.0* A pop up asking if I want to buy the pro version pops up whenever I open the app with no way to disable it. ### 1/5 — Data mining *2021-10-14, version 1.7.0* It makes the frames drop and glitchy specilly when i split screen **Developer response:** If you are having performance issues please contact our support as this is likely an issue on your specific device. ### 2/5 — Hate the new free color choices! *2024-11-12* Recently got a new iPad and put the Omega calculator onto it. I no longer have the wonderful green color I previously had for free. Now it’s a hideous combination of blues and orange. So very sad that the green is now a purchase color and the free options are blue, pinks, or grays. Loved this calculator but now looking for a better looking one. Sooo sad! **Developer response:** Hi, Sorry about that, please contact support and we can get this sorted out for you! ### 2/5 — Nice calculator but *2023-08-16, version 2.2.0* I really like this app and I had bought a $3.99 theme back a while back... but it seems to have been removed and I no longer have access to any of the themes. I’d have to pay $9.99 now! ### 5/5 — Best calculator period *2025-12-30, version 2.2.1* Back to basics. The app file size is smaller than offloaded default iOS apps. This is a barebones calculator with more useful features than anything else on the market. It’s lightweight and simple, and I use it for work every day. My only fear is it goes away because there’s nothing like it. ### 5/5 — Hate the new free color choices! *2024-11-20, version 2.2.1* Update: Support reached out to me and restored my color choice. Thanks! Recently got a new iPad and put the Omega calculator onto it. I no longer have the wonderful green color I previously had for free. Now it’s a hideous combination of blues and orange. So very sad that the green is now a purchase color and the free options are blue, pinks, or grays. Loved this calculator but now looking for a better looking one. Sooo sad! ### 5/5 — It's so good *2024-03-27, version 2.2.0* Make pro free ### 5/5 — App size is only 8.8 MB (not GB). No bloat. Perfect. *2023-11-13* I never leave reviews, but this app deserves it. In an app world full of bloat where the top rated calculator apps are somehow almost 1 GB in size, this app stands out. I don’t have to worry about excessive (or any) telemetry. I don’t need to worry about this calculator running in the background or what have you. It’s barebones as possible and only 8.8 MB in size, and it does what it’s supposed to. You don’t need to pay for this app for its full benefits, but I did just so the app maker doesn’t abandon this project. ### 5/5 — Absolutely Love the Graphing Feature. *2023-06-14, version 2.1.0* Don’t need to fix my broken TI-84. Brilliant. - John Seonggggg (Swift Challenge) ### 5/5 — Good app *2023-06-07, version 2.1.0* Any way to get the old button layout back? It’s nice having exponents and square root on the main screen ## Most praised reviews (4 highest-rated) ### 5/5 — 1 X 1 = 1 *2022-10-28, version 2.0.1* 2+2=4 ### 5/5 — Wow! *2022-10-05, version 2.0.0* Awesome! Now I know what is pi times pi! ### 5/5 — Good App *2022-09-29, version 2.0.0* No ads, many themes perfect thank you!! ### 5/5 — A TI-84 Calculator on Your Phone *2022-09-22, version 2.0.0* No other calculator has the functionality and detail that Omega Calculator has. Whoever the developer is really put in specific, catered thought and time to create a calculator that goes beyond the capabilities of other IOS calculators. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
