BiliCalc vs SPIRO
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
BiliCalc
This app calculates phototherapy thresholds for newborns based on age, bilirubin levels, and neurotoxicity risk, referencing AAP guidelines. It displays values on a phototherapy nomogram and identifies the patient's risk zone using the Bhutani Nomogram.
- Calculates phototherapy threshold for newborns
- Displays values on phototherapy nomogram
- Identifies patient risk zone using Bhutani Nomogram
- Calculates age from birth and lab times
- Direct links to reference articles and risk factors
- Supports US and SI units

BiliCalc is a neonatal bilirubin calculator and clinical reference for healthcare professionals caring for newborn infants born at 35 or more weeks of gestation. Calculations are based on the 2022 American Academy of Pediatrics (AAP) Clinical Practice Guideline for the management of hyperbilirubinemia in newborn infants 35 or more weeks of gestation. Enter the infant's postnatal age, gestational age at birth, bilirubin value, measurement type, applicable neurotoxicity risk factors, and phototherapy status to view: • Patient-specific phototherapy, escalation-of-care, and exchange-transfusion thresholds • A graph displaying the bilirubin value and applicable treatment thresholds • Guideline-based treatment recommendations • Post-discharge follow-up guidance, when applicable No internet connection is required for calculations. BiliCalc performs calculations locally on the device and can be used without Wi-Fi or cellular data. BiliCalc is designed for quick clinical reference and does not measure bilirubin. Bilirubin values and other clinical information must be obtained independently and entered by the healthcare professional. Clinical references and links to source material are available within the app. BiliCalc is intended to support, not replace, professional clinical judgment. It is independently developed and is not affiliated with, sponsored by, or endorsed by the American Academy of Pediatrics.
SPIRO
This medical app assists healthcare professionals and students in interpreting spirometry tests. It provides diagnostic and treatment suggestions based on entered data and offers access to educational materials and respiratory health guidelines.
- Interpret spirometry tests
- Diagnostic suggestions
- Treatment suggestions
- Access respiratory guidelines
- Educational material
- Patient follow-up tool

Objective measurement of respiratory function is of primary importance in the assessment of chronic obstructive pulmonary diseases. However, the interpretation of respiratory function tests, especially spirometry tests, is considered suboptimal in primary care. A team from the Quebec Heart and Lung Institute affiliated with Laval University (IUCPQ-UL) developed an interactive mobile application called SPIRO© to facilitate the interpretation of spirometry tests. The SPIRO© app guides healthcare professionals and medical students in interpreting spirometry tests by entering basic data from a spirometry report (FEV1, FVC, FEV1/FVC). The software gives a diagnostic suggestion to the user based on pre-set intervals. In addition to being a resource for educational material (explanatory video, questionnaires, documents related to respiratory health guidelines), the SPIRO© application guides the user in applying the guidelines in respiratory health by providing the necessary references (scientific articles, respiratory health guidelines) to develop a treatment plan. The app allows: - Optimizing interpretation of spirometry; - Obtaining a diagnostic suggestion; - Obtaining a treatment suggestion according to respiratory guidelines; - Getting quick access to respiratory health guidelines; - Facilitating the work of health professionals; - Carrying out better follow-up of patients with chronic obstructive pulmonary disease (COPD) or asthma; - Obtaining continuing education through specific and relevant educational material. This tool was developed by the Chair in Knowledge Translation, Education and Prevention in Respiratory and Cardiovascular Health affiliated with Laval University in collaboration with the IUCPQ-UL.
