NO SE ACTUALIZA DESDE HACE MUCHO

Bonjour
Bonne appli, fonctionnelle et intuitive. 
Pourriez vous ajouter le score TRiP(cast) ?

Merci

### 4/5 — Bitte neue Scores

*2024-06-19*

Super App, aber viele neue Scores z.B SCORE2 fehlen. Außerdem wären es schön Klappenvitien berechnen zu können.

### 3/5 — Problema com o app

*2023-09-20*

Uso o app há mais de 1 ano, porém essa semana ele iníciou com problemas. O aplicativo não abre mais. Gostaria de saber o que está acontecendo

### 4/5 — Manque certaines formule, sans mise à jour depuis longtemps

*2023-09-01*

Certaine scores assez classique sont manquant.
Il semblerait que la base de données ne soit pas souvent mise a jour ?
Sinon l’utilisation est intuitive et simple.

### 4/5 — Muito útil!

*2023-08-18*

Muito útil! Porém, deveria ter disponível calculadores de doses de DVA, medicações comuns da pediatria e cálculos de reposição de eletrólitos/soro de manutenção adultos e pediátricos.

### 3/5 — Debe mejorar

*2023-01-15*

Falta fórmulas importantes como GUPTA (riesgo neumonia, falla respiratoria, riesgo perioperatorio) AWOL (riesgo de delirium) CAM tradicional.
Ojala las agreguen

### 3/5 — Agregar app

### 4/5 — Me gusta

### 1/5 — Previously free calculators now require subscription

*2026-01-02*

I have used this app for years. However, the ascvd risk calculator, which use to be free, now requires a premium account. This calculator is free in so many other apps. Will delete this app and use an alternative. I understand an app needs to make money, but provide an option with ads versus abruptly cutting off busy providers in the midst of their clinic without a heads up.

### 1/5 — Very very limited!

*2023-03-17*

We need so many more ICU Calculations, and an AHI Calculation. This is so limited

### 1/5 — Viele wichtige Formeln fehlen

*2022-11-20*

Man kann Vorschläge einreichen, aber die werden anscheinend nie bearbeitet. Im Notfall fehlen die wichtigsten Formeln. Dafür dass die App kostenpflichtig ist ziemlich schwach.

### 1/5 — Retiraram as calculadoras de doses

*2022-01-11*

Retiraram as calculadoras de doses

### 1/5 — Poco recomendable

*2021-09-22*

Poco recomendable, compras la aplicación y con el paso del tiempo te solicitan la actualización y tienes que pagar otra vez 😡😡😡😡 es engañosa. Se está enriqueciendo el desarrollador

### 1/5 — Eu tinha outra versão e perdi

*2021-09-14*

Eu tinha outra versão. Mudou o sistema do IOS e a parou de funcionar. Agora vem o mesmo APP e não consigo usar sem pagar de novo… me sinto frustrado com esse desenvolvedor, não recomendo.

**Developer response:** Desculpas pela confusão. A atualização da nova versão aconteceu em 2014 e, desde então, apenas 1 desbloqueio é necessário para usar todos os recursos do aplicativo.

### 1/5 — Absturz Absturz

*2020-04-11*

Stürzt seit einem Monat nur noch ab. Nachbesserung?

### 1/5 — Restricción que no se vale

*2019-08-17*

Yo compré esta aplicación cuando tenía libres todas las formulas es una tristeza que por una actualización obligada te retiren las fórmulas que mas requieres en el día a día y cuando las solicitas te cuestan un dineral. Acaso no es extorsión a población cautiva

**Developer response:** Sorry for the frustration! Please note that if you previously purchased MedCalc version 3, you can unlock MedCalX for free. See our step-by-step instructions here: https://medcalx.ch/support.html#freeupgrade

### 1/5 — Se cierra inesperadamente.

*2018-12-12*

La aplicación tiene problemas para iniciar inmediatamente se cierra tanto en iPad o en iPhone la eh borrado y la eh vuelto a instalar y es imposible trabajar en ella debido a que se cierra inesperadamente.

**Developer response:** Hey Emmanuel, lamento escuchar! Si pagó y las fórmulas aún no están desbloqueadas, contáctenos en questions@medcalc.uservoice.com

### 1/5 — Pagué por ella

*2018-12-02*

La compré funcionó un tiempo y ahora ya no funciona. Qué pasa??

A GREAT pocket reference I've used daily for years but just now getting around to writing a review.

### 5/5 — Лучший калькулятор

*2022-04-29*

Самый функциональный калькулятор! Очень большой охват, доступны все единицы измерения прямо в форме ввода данных. Никакой «воды». Очень жаль, что не обновляется. Хотя, может быть обновлять и добавлять нечего…

### 5/5 — Muy util

Muy util, pero definitivamente requiere de actualización frecuente

### 5/5 — Práctica y sencilla

*2020-04-05*

Es una calculadora muy sencilla de utilizar y contiene bastantes fórmulas aunque algunas han ido desapareciendo. Me gusta que incluye la fuente de donde se basan estas fórmulas.
