### 5/5 — Exelente

*2026-08-02*

Vale muito a pena

### 2/5 — Fastidieux

*2020-10-06*

- Les résistances exprimées avec 10 décimales et une puissance négative.

- La nécessité de sélectionner une formule de calcul.

- Faut appuyer sur le bouton calcul pour calculer, ça pourrait se faire automatiquement.

### 2/5 — Nags for raitings

*2020-09-04*

Title says it all.

### 3/5 — Almost too basic.

*2018-01-07, version 1.2.0*

The biggest problem I found was that there is no decimal point keyboard button displayed. You have to push the question mark to get a decimal point. Also there is no landscape mode for iPad. These seem like basic standard feature that should be available for all apps free or paid versions.

### 1/5 — Doesn't work in landscape orientation

*2017-08-24*

Will not rotate to landscape so it is only usable in portrait mode.
