EndoData vs Valve PPM
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
EndoData
This medical reference tool helps measure endoscope deflection angles by comparing the angulated scope to an on-screen image. It includes angulation and other key specifications for popular Olympus, Pentax, and Fujinon flexible endoscope models, ideal for PM programs and evaluations.
- Measure endoscope deflection angles
- Compare angulated scope to on-screen image
- Includes Olympus, Pentax, Fujinon specs
- Reference for PM programs
- In-service evaluation tool
- Commonly referred specifications

EndoData-Pro flex is a reference tool that can be used to quickly measure the deflection angles on all listed Olympus®, Pentax® and Fujinon® flexible endoscopes by comparing the angulated scope to the picture on the Apps angulation screen. This app is ideal for PM programs and in-service evaluations. We've included angulation specifications along with other commonly referred to specifications for the most widely used endoscope models. The EndoData-Pro App contains mainly US Endoscope models but also includes some non-US models as well. All listed specs were collected from what we believe to be accurate data. However, we are not responsible for possible inconsistencies with existing oem data. If you're working in the Medical Endoscopy Field, you will find EndoData-Pro an invaluable tool and the only one of its kind!
Valve PPM
This tool assists medical professionals in assessing implanted prosthetic cardiac valves. It offers guidance for checking existing valve function and selecting the optimal valve before implantation based on patient and prosthesis parameters.
- Assess implanted valve function
- Select optimal valve before implantation
- Analyze patient and prosthesis parameters
- Identify potential patient-prosthesis mismatch
- Determine intrinsic prosthesis dysfunction

Valve PPM is an innovative mobile tool developed to support echocardiography professionals in their effort of assessing the functionality of implanted prosthetic cardiac valves. The application provides guidelines for assessing an already implanted valve (Check Valve Function) and for choosing a valve before implantation (Optimal Valve Selector). The algorithms behind the App have been derived after an extensive research of the published materials on the aortic and mitral prosthetic valve assessment. - Check Valve Function After selecting a particular valve type, the patient characteristics (weight/height) and the prosthesis actual parameters (peak velocity, mean gradient, VTI prosthesis, VTI LVOT and LVOTd), Valve PPM will provide the user with an answer regarding the normal function of the valve, the potential patient prosthesis mismatch or the intrinsic prosthesis dysfunction. - Optimal Valve Selector The user will be required to select a valve position (aortic/mitral) and the patient characteristics (weight/height) and Valve PPM will instantly indicate the minimum Effective Orifice Area (EOA) in order to avoid Patient Prosthesis Mismatch (PPM).

Verdict
The clearest difference is price: Valve PPM at Free against EndoData's $6.99. Valve PPM also leads on review sentiment (100% vs 67%) and update cadence (every 2 months vs every 5 months). EndoData's advantage is iOS requirement (11.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.
