MAPPP vs SplenoCalc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
MAPPP
This medical guide assists clinicians in managing patients on anticoagulation therapy undergoing surgery or invasive procedures. It helps evaluate bleeding and thrombosis risks, guiding decisions on interrupting anticoagulation and using bridging therapy.
- Evaluate bleeding and thrombosis risk
- Guide anticoagulation interruption
- Provide bridging therapy guidance
- Detail drug dosing
- Offer laboratory monitoring advice
- Encourage clinician communication

Despite the considerable efficacy of antithrombotics and the increased number of oral anticoagulants now available, preventable bleeding and thrombotic events are still unacceptably common. While recently marketed agents require less laboratory monitoring, problems with the clinical management of anticoagulated patients persist, particularly in the peri-procedural period. Surgery and invasive medical interventions increase the risk of bleeding, while withholding anticoagulants increases the risk of thrombosis due to the underlying condition(s) for which anticoagulation was originally prescribed. The clinical team must therefore balance these competing risks and make educated decisions regarding the decision to interrupt oral anticoagulation for a medical procedure and, if interrupted, whether to "bridge" anticoagulation with injectable anticoagulants, such as low molecular weight heparin (LMWH) in warfarin treated patients. This guide is intended to: -Assist clinicians in the simultaneous evaluation of procedure-related bleeding risk and underlying risk of thrombosis -Guide decisions regarding the interruption of anticoagulation and the use of anticoagulant "bridging" -Provide detailed guidance for drug dosing and laboratory monitoring in the peri-procedural period -Encourage clear communication between clinicians involved in prescribing anticoagulants and performing invasive procedures This material was created by the multidisciplinary members of the Peri-Procedural Task Force of the New York State Anticoagulation Coalition and IPRO, the Medicare Quality Improvement Organization for New York State, under contract with the Centers for Medicare & Medicaid Services (CMS), an agency of the U.S. Department of Health and Human Services.

SplenoCalc
This medical app calculates approximate spleen size percentiles based on user height and gender. It utilizes an algorithm derived from height- and gender-corrected normal values for spleen length and volume. The app provides additional informational insights related to these calculations.
- Spleen size percentile calculation
- Height and gender correction
- Normal value-based algorithm
- Spleen length and volume data

Spleen size is significantly influenced by body height and gender. The Splenocalc App is designed to calculate approximate percentiles of an individual´s spleen size. The algorithm of the Splenocalc App is based on the height- and gender-corrected normal values for homeostatic spleen length and volume (for women between 155 and 179 cm and men between 165 and 199 cm body height), the Splenocalc App is performing these calculations and is providing additional information.
