epTools vs Walking Doctors
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
epTools
This app provides a suite of tools for diagnosing and managing cardiac rhythm disorders. It offers algorithms for localizing arrhythmias, differentiating conditions like WPW from FVF, and assessing disease risks. Users can visualize progress, save analysis paths, and access cited scientific references.

Trusted for over 15 years by heart rhythm professionals worldwide, epTools is a collection of useful tools for the evaluation of heart rhythm disorders. It is available on iPhone and iPad devices. Resources include algorithms used to localize arrhythmia substrates and reference guides to assist in the identification and, management of cardiac rhythm disorders and tools to calculate commonly used measurements and risk scores. Peer-reviewed algorithms are implemented by tools via an intuitive user interface. References are provided. Tools guide the user or AI through a series of questions to arrive at an answer while providing a graphical visualization of their progress and result of their analysis. Use of the save path to image feature allows users to save an image of the current decision path when using many of the decision analysis tools included. These images, which appear in the photo album, may be useful to communicate findings with colleagues. Included tools: Preexcitation variant localization: Arruda, Milstein, Taguchi , D'Avila, Li, Pambrun, Baek and Crinion and O'Leary et al. Atrial tachycardias: Ellenbogen and Kistler et al (localization ) De Ponti et al tool (calculates the appropriate mapping window for isthmus identification) Miyazaki et al (localizes macro reentrant ATs based on pacing responses) Ischemic ventricular tachycardia localization: Miller, Segal and Andreu et al) Idiopathic ventricular tachycardia and premature ventricular contraction: Ito, Park and Enriquez et al (localization) ABC-VT Risk Score Differentiation of left vs right ventricular outflow tract sites: QRS-RVA Interval V₂S/V₃R Index TZ Index V₂ Transition ratio R/S-wave Amplitude, R-Wave Duration, R-wave amplitude, V₂QRSI40 and RV₁-₃ indices.

Verdict
The clearest difference is price: Walking Doctors at $1.99 against epTools's $19.99. Walking Doctors also leads on update cadence (monthly vs every 4 months) and rating (5.0 vs 4.8). epTools's advantage is ratings volume (519 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
epTools costs $19.99 and Walking Doctors $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Walking Doctors holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: epTools has 519 ratings behind it against 1, so its average is the more settled of the two.
epTools ships an update every 4 months, Walking Doctors monthly. The most recent releases landed on October 12, 2026 and October 6, 2026 respectively.
