Версия про. ### 5/5 — Calculator *2023-02-06* This app works for 99% of my math needs. Definitely worth having. ### 5/5 — Brilliant App. *2022-11-29* It’s a calculator, and it works fine. A very useful tool. ### 5/5 — Дополнительные возможности *2022-09-07* Очень хорошее приложение. Предлагаю сделать ещё подсчёт времени , байтов и других не кратных 100 величин. Спасибо. ### 5/5 — Look no further *2022-07-01* The only calculator you will need. ### 5/5 — One of the best *2021-12-22* User friendly interface and work with real time calculations.Different colour options should also be provided. ### 5/5 — My favorite historical calculator *2021-11-16* Favorite calculator, functional and beautiful. ### 5/5 — Sehr praktischer Rechner für hohe Zahlen *2021-06-06* Besonders toll ist, dass Zahlen ausgeschrieben in Wörtern angezeigt werden. Das vereinfacht das rechnen mit sehr vielen Nullen oder hochstelligen Zahlen. Gut sind auch die acht Arbeitsbereiche, die man parallel befüllen kann. Der Rechner ist ideal für kaufmännische, wie auch wissenschaftliche Berechnungen, bei denen man auf eine Tabellenkalkulationen verzichten möchte. Im Prinzip ist er so, wie früher die guten alten Papierrollen-Rechenmaschinen. Aber sehr komfortabel mit acht virtuellen Papierrollen! So hat man bei langen Berechnungsfolgen immer noch den Überblick und kann zwischen den Arbeitsbereichen („Papierrollen“) hin und her wechseln. ### 5/5 — 必须5⭐好评 *2020-12-29* 这是第一款我专门购买且来评论的好软件！ ### 5/5 — My only one Calculator *2020-12-24* Perfect in all ways. After using a free version I switched to pay one. The owner - creator is easy in contact, he replied my questions and other requests. ### 4/5 — Калькулятор *2020-12-02* Давно, были глюки. Пока исправно. Благодарю. Пользуюсь давно. ### 5/5 — Great on IPad *2020-11-28* This is great on IPad but on iPhone i frequently miss hit the decimal due to the two dots just below decimal but it’s still a very good calculator with 9 workspaces ### 4/5 — AMEI MUITO DE VERDADE MAS ESTÁ MUITO PEQUENO AS LETRAS *2020-11-19* AMEI MUITO DE VERDADE MAS ESTÁ MUITO PEQUENO AS LETRAS Por favor aumente por favor eu melhoro até a nota ### 5/5 — Лучший калькулятор *2020-09-07* Лучший калькулятор, стоит своих денег, покупайте и кайфуйте. Перепробовал много, этот и бесплатный хорош, ну если не брать в учет рекламу, решается просто, запретом приложению пользовать сотовую связь :) ### 5/5 — 프로가 있는 줄 몰랐어요 *2020-08-10* 무료버전 쓰다가 너무 좋은데 광고가 많아졌더라구요 음악재생이 끊겨서 불편하다가 설정에 들어가보니 프로가 있는걸 발견하고 구매했어요 =누르기 전에 결과가 나오고 수정도 쉬워서 좋아요 잘 쓸게요 ^^! 유료쓰다가 프로로 넘어오니 하단 광고가 사라져서 계산기숫자패드가 훅 아래로 내려가서 당황스럽긴 하지만 ㅎㅎㅎ 광고 안나오니까 좋아요 ### 3/5 — Very simple design and easy to use. *2020-07-07* However, I would like the buttons to be a little bigger. I also want the backspace key to be placed on the number side. If I turn the tablet screen sideways, the calculation history is not displayed. Please improve it. **Developer response:** Please send us an e-mail to help@smallte.ch . We will be happy to help you ! ## Most critical reviews (10 lowest-rated) ### 1/5 — Poor visuals *2022-04-24* Ever since a random update they did last year, when you switch apps and then switch back to the calculator half of the background is a different color for no reason. I’ve sent them at least a dozen requests in the last year to fix it. They keep saying they will… and then nothing ever comes of it. EXTREMELY poor customer service. ### 1/5 — Tela piscando! *2020-04-13* Senhores, como resolver o problema da tela piscando?! **Developer response:** Envie-nos um e-mail para help@smallte.ch. Será um prazer ajudá-lo! ### 1/5 — Исправьте дерганье экрана *2020-04-03* Последнее обновление -дёргается экран!!!! ### 1/5 — Обновление не удачное *2020-03-06* После обновления появился красный прямоугольник поверх калькулятора. Настройки упростили. Верните как было. ### 1/5 — It stops your music player!!! *2020-01-16* When I open this app the music I have playing on my device stops playing!! Even if I start it again, the music stops when I start using the calculator. Going to have to find something else until this problem is resolved, it's a shame though cuz I really like this calculator app otherwise. ### 1/5 — Не работает! *2019-08-10* При вводе цифрового значения курсор становится спереди, поэтому нельзя удалить последние введённые цифры. Цифровые значения вводятся зеркально. Очень плохо! Как обновить приложение? ### 1/5 — Хуже родного *2019-02-24* Встроенный калькулятор лучше. Содрали 374 рубля. ### 1/5 — Bug *2018-09-04, version 1.58* Logs are low precision ### 2/5 — Anzeigefehler *2021-11-15* Leider tritt ein Anzeigefehler auf, wenn man das Programm unterbricht, oder wenn man die Splitscreen-Option wählt. Auf mehrfache Anfrage beim Hersteller keine Reaktion. Schade. **Developer response:** Bitte schreiben Sie uns eine E-Mail an help@smallte.ch. Wir helfen Ihnen immer gern! ### 2/5 — Дергается экран *2020-03-13* Из за последнего обновления при работе с калькулятором начал моргать экран очень часто, сильно раздражает. Айфон 11 ## Most praised reviews (10 highest-rated) ### 5/5 — A melhor sempre! *2025-06-06* A melhor calc que uso já há anos. Usei por um bom tempo a versão free, então adquirir a Pro nada mais foi do que um cafezinho de agradecimento ao desenvolvedor desta maravilha. Mesmo depois das melhorias que a Apple vem fazendo na original do iPhone, este app aqui acaba ainda sendo o melhor! A visualização do histórico e as páginas são algo sem preço! E ainda mais do que isso, o design - que está melhor do que essa única screenshot da loja 😂 - os sons de resposta…. Enfim, passando para fazer jus a este app que me acompanha há tempos e agradecer ao seu desenvolvedor por mantê-lo na loja ao longo de todos esses anos. Continue assim 🙏🏻 ### 5/5 — Parfait *2024-11-13* Calculatrice qui permet l’historique et son traitement. Bon achat. ### 5/5 — カッコいいし実用的 *2024-09-14* 純正より良いので、愛用してます。 ### 5/5 — I use it every say *2024-09-01* In my opinion, the best calculator App. Brilliantly designed, intuitively to use. ### 5/5 — Great *2024-06-16* The best ### 5/5 — Meilleur calculatrice sur IPHONE *2024-05-30* Vraiment la best calculatrice sur IPHONE ! ### 5/5 — Just get it *2024-03-29* For a few bucks it saves a lot of frustration. I’m sure you waste more money on coffee in a week, just get it. ### 5/5 — 值得购买，支持开发者。 *2024-01-19* 细节的设计考虑到了实际的用处，方便了使用者。 ### 5/5 — Good *2023-11-03, version 1.65* Best ### 5/5 — I like everything *2023-10-20* fix it - the widget is buggy!!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
