That is what this was for about 10 years. Unfortunately now every few times I use the app and just want to do a quick calculation I get a prompt about why I should upgrade to the new premium plan or something. I don’t agree with the new monetisation strategy for this app (I will pay a one off premium price, but I will not subscribe to a calculator), but I appreciate the developer is not forcing long-time customers to upgrade. However, everything is geared towards encouraging you to do that. For that reason, and because I’ve never really liked the interface, I will be moving on. ### 4/5 — One time purchase now requires a subscription *2026-01-22* I purchased this calculator and have enjoyed it for years. It was advertised as one-time purchase. Now with the latest version it is popping up a subscription authorization screen every time I press the equals button asking for a subscription. It has also disabled a lot of the unit conversion functionality. You can’t offer a product as a one time purchase and then years later after the sale come back requiring me to pay you more money. If this is not resolved soon I will delete the app and never purchase anything else from this developer. UPDATE: this has been fixed and is no longer requesting a subscription. Thanks for fixing this. I will update my review. **Developer response:** This was an error on our part, legacy user were never supposed to be required to subscribe. It should be all fixed now since v3.7.3. You can always reach us via UserVoice in the app or support@qapps.com if you have any issues or suggestions. Thanks! ### 3/5 — Best Calc *2025-10-16, version 3.6.10* Best one I’ve found yet, but no hex dec bin conversions. Seems to only have hex, and no way to enter hex, only converts dec to hex, one way. ### 4/5 — Good *2025-09-22, version 3.6.10* Please remove the in-app purchases. ### 3/5 — Feedback *2024-07-21, version 3.5.60* No way to easily enter hex numbers. Their feedback site is not working, so posting here. Holding the bar to the left of the number pad to toggle it for A-F would be much better. ### 5/5 — Great app!! *2023-12-11, version 3.5.51* Great app!! Clean, minimalist and fast!! ### 5/5 — Leicht und übersichtlich *2023-12-10, version 3.5.51* Besonders die aufgeführten Einzelposten bei der Summen-Funktion gefallen mir. ### 5/5 — Excellent App *2023-12-07, version 3.5.51* I use this calculator all the time with excellent results! ### 5/5 — Calk. Hip-hip! *2023-11-25, version 3.5.49* ! ## Most critical reviews (10 lowest-rated) ### 1/5 — НЕВОЗМОЖНО ПОЛЬЗОВАТЬСЯ! *2026-04-24* Каждый раз при нажатии на равно, на «С» и тд вылазит предложение оформить платную подписку! НЕВОЗМОЖНО ПОЛЬЗОВАТЬСЯ КАЛЬКУЛЯТОРОМ! **Developer response:** Бесплатно только для пробного использования. После подписки будут доступны все функции. ### 1/5 — несмотря на то что купил приложение раньше требует подписку *2026-01-01* периодически требует подписку несмотря на то что ранее купил это приложение. Сделайте отдельную версию с подпиской и оставьте в покое тех кто поддержал Вас купив это приложение!!!! ### 1/5 — Full of annoying popups now *2025-12-24, version 3.7.6* After recent update there are CONSTANT popups reminding you to give the devs money for a calculator even AFTER you bought it. They made the widget super laggy too, it just gets worse and worse with every update. ### 1/5 — Всплывающая реклама *2025-11-06* Теперь каждый раз, когда я нажимаю равно ,у меня вылазит предложение о подписке , мне нравился этот калькулятор , но если это не изменится , придется удалить приложение… **Developer response:** Это была наша ошибка — от постоянных пользователей никогда не требовалось оформлять подписку. Начиная с версии 3.7.3, всё должно быть исправлено. Если у вас возникнут какие-либо проблемы или предложения, вы всегда можете связаться с нами через UserVoice в приложении или по адресу support@qapps.com. Спасибо! ### 1/5 — Subscription *2025-11-06, version 3.7.2* Used it for a long time until they required a subscription from me today. Pass. ### 1/5 — One time purchase now requires a subscription *2025-11-06* I purchased this calculator and have enjoyed it for years. It was advertised as one-time purchase. Now with the latest version it is popping up a subscription authorization screen every time I press the equals button asking for a subscription. It has also disabled a lot of the unit conversion functionality. You can’t offer a product as a one time purchase and then years later after the sale come back requiring me to pay you more money. If this is not resolved soon I will delete the app and never purchase anything else from this developer. **Developer response:** This was an error on our part, legacy user were never supposed to be required to subscribe.

Thanks! ### 1/5 — Subscription *2025-11-05* I bought this app years ago when there was no Apple calculator app on the iPad. Now all of a sudden CALC Smart Calculator wants to charge me a subscription fee. For what? It doesn’t do anything better since I bought it. And it doesn’t do anything that the Apple Calculator does already. Total Ripp-Off! I’ll just delete it from my iPad. **Developer response:** It shouldn’t be asking you as a long time user - did you try to restart? Sorry you feel the way, there are lot of advantages over other calculators and plenty of changes over the years. You can always reach out via Help in the app to resolve any issues you have including the one you are experiencing, we can’t help you here. Thanks 🙏 ### 1/5 — Used to be great then introduced subscription pricing *2025-11-04, version 3.7.2* Used to be my favourite calculator for iOS and felt the developers really listened. However, recently introduced a subscription rather than a flat fee, which is ridiculous for a calculator whose core functionality hasn’t changed for many years. Have now moved to an alternative app. ### 1/5 — In what world does a calculator need Location permission Garage man!! *2025-02-13, version 3.6.5* Uck, yuck, definitely gross a simple app overstepping its need to data mine vs it’s need to be customer friendly and act appropriately to be ethical and honest SaDlY this isn’t the case here 🥲🤮😨🤥 ### 1/5 — Why did you change the design. *2024-10-10* I loved this app and have used it for many years. It was perfect. However, with todays update the design has changed. The numbers for the calculation and answer section are huge! The number keyboard was made smaller and I am typing numbers and functions incorrectly because of the change. Who asked for this? Please change it back to the original version. **Developer response:** You’d be happy to know that in the latest update v3.6.2 we have adjusted the sizing to be closer to the original and to make it even better - now with the new custom theme designer - you have the ability to change the proportions between the top and bottom sections yourself 💪 ## Most praised reviews (10 highest-rated) ### 5/5 — Arithmetic your terms… *2025-10-04, version 3.6.10* …really nice calculator for macOS. ### 5/5 — خايسه *2025-04-16, version 3.6.5* زي الكلب ### 5/5 — One of the finest *2025-03-06* One of the finest (if not the finest) calculators in the App Store. Too many amazing and useful functions to list here. Just download it, and see for yourself. ### 5/5 — Smart Calculator *2025-01-19, version 3.6.5* Excellent App ### 5/5 — Wonderful app *2025-01-06, version 3.6.4* Love the app, love the devs. Seriously underrated app and you should buy it! You won’t regret it. In addition, its nice that siri can use the app for calculations via dictation, and then you can pull up the app with one click. Love the widgets too. If I had one suggestion, I wish that it was more similar to a TI-84 calculator, only in the sense where I could see that last 3-5 calculations. I would find it much more useful than only being able to see one present calculation. ### 5/5 — После обновления формат калькулятора стал сжатый по вертикали iPad mini 5. *2024-12-13* Можно исправить пожалуйста. Сжатый по вертикали , до обновления было нормально . iPad mini 5 **Developer response:** Похоже, вы случайно изменили размер верхней панели. Чтобы исправить это, зайдите в Настройки > Темы и отрегулируйте верхний ползунок по своему вкусу.

I use it daily. ### 5/5 — Best App! *2024-03-09* Calc is a great, easy to use app. I use it every day: investment performance, interest calculations, and simple add, subtract etc. much better that separate calculator.. ### 5/5 — Неплохой калькулятор *2023-12-22* Неплохой калькулятор пользуюсь давно около пяти лет на замену штатному в iPhone ### 5/5 — Отличный калькулятор *2023-12-14* Классное приложение, наверно, лет 10 использую на айпаде, удобное и есть история вычислений + можно строить выражения, всё как надо --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
