FisioChecks

FisioChecks brings 23 respiratory physiotherapy and intensive care calculations and scales into one app, built to be used one-handed, at the bedside, at any hour of a shift.

Open it, type the values, read the result. No sign-up, no login, no internet needed to calculate.

BUILT FOR THE BEDSIDE
• The result stays pinned at the bottom of the screen and updates as you type.
• Severity is shown by color, icon and text — never by color alone.
• When a result cannot be calculated, the app tells you why instead of showing a wrong number.
• Values outside the expected range raise a warning, but the calculation still runs: a patient may be outside the pattern.
• Every calculation cites its published reference. Where the source is silent or still awaiting clinical review, the app says so on screen.
• Search by name, acronym or alias, plus favorites and history.
• Saved records for each calculation, to look back on later.
• English, Brazilian Portuguese and European Portuguese. Light and dark themes. Works on phones, tablets and foldables.

YOUR DATA STAYS ON YOUR DEVICE
The values you enter, the results and your saved records stay on your device only. The app has no sign-up and no free-text fields, so there is nowhere to enter a patient's name. No clinical value is ever sent to us or to anyone else.

FREE, WITH ADS
FisioChecks is free and shows a banner in a reserved area that never covers content or buttons. Calculating and deleting records are always free. Each calculation keeps 3 records at no cost; to save one beyond that, you can watch an ad.

IMPORTANT
FisioChecks is a calculation aid for healthcare professionals. It does not replace clinical judgement or your institution's protocols. Check the values and results before any clinical decision.
