Please fix this serious issue and I will gladly rate it a 5. Thanks! ## Most critical reviews (10 lowest-rated) ### 1/5 — Does NOT Work *2026-04-21* Does NOT Work ### 1/5 — Parou de funcionar *2026-02-03* O app chega a abrir como se a calculadora estivesse desligada. Tento aplicar o comando de ligar, mas não há alterações. Percebe-se que qualquer tecla acionada reage como se o comando tenha sido executado, mas não é resposta do comando à calculadora. ### 1/5 — Needs Updating *2026-01-10* I loved this app, but it no longer functions under the latest iOS. ### 1/5 — Trava *2025-06-05* Já perdi minhas fórmulas várias vezes tendo que resetar.

Nao vale a pena! ### 1/5 — Dinheiro fora *2021-09-18* Não abre programas e nem transfere ### 1/5 — Crashed and burnt *2021-05-09* I was symbolically solving the system of equations x^2+y^2=r1 and (x-a)^2+(y-b)^2=r2 subtracting one from the other then expanding, collecting and solving for y then substituting and solving for x then the app froze solid and I had to remove it and reinstall it again losing all of my data. YIKES!!!!!! ### 1/5 — Very slow & unstable *2020-12-08* Very slow to respond to key pushes, code is unstable and often crashes. ### 1/5 — se cuelga *2020-10-10, version 1.3.3* sorpresivamente deja de funcionar. la única forma de hacer que funcione de nuevo es desistalar la app y volverla a instalar. ## Most praised reviews (10 highest-rated) ### 5/5 — iOS 26.3 iPhone 16 *2026-02-17* Just installed on the iPhone16 pro and fully working.

This is a great app and I look forward to seeing future enhancements. Great job! ### 5/5 — Access to the file manager to install programs *2020-04-11, version 1.3.3* carry out an update to be able to install the programs in the libraries of this calculator and have a connection with the file managers of the iPhone or ipad, since third-party programs are the main virtue of this calculator --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
