All I wanted was a resizeable calc with a viewable history and this provided perfectly

### 5/5 — All Rounder

*2026-08-01, version 2026.8.1*

Solves is a Calculator with features I have been waiting for since I started using calculators in devices! They should add some more cool & 3D glass type skins and also should release for Windows & Linux versions!

### 1/5 — Stop asking me everyday to upgrade

### 5/5 — nice app

*2026-05-13, version 2026.3.22*

very useful

### 5/5 — Very Good!

*2026-03-14*

I was looking for an upgrade to the native Apple calculator that would provide a history of calculations (a tape). Solves does this well and works on iPhone, iPad and Mac. I almost stopped using it because of no clear or clear all key, but the developer built in the clear function as a swipe up. You can also turn the clear key on in settings if you want a physical key. Now it’s exactly the calculator I wanted!

### 5/5 — Calculadora espetacular

*2026-02-05, version 2026.1.11*

A melhor e mais funcional calculadora que eu já utilizei no iOS. Preço muito justo (e até barato) para o que é ofertado aqui. Meus parabéns ao desenvolvedor por todo o trabalho e responsividade.
