The RadOnc Toolbox is a resource for health care professionals that is designed to support evidence-based practice. This point-of-care tool compiles frequently accessed references related to the delivery of radiation therapy, including dose constraints, calculators, clinical practice guidelines, staging, and other oncology resources. The RadOnc Toolbox was created by Malolan Rajagopalan, MD, MBA, who was Principal Investigator of a grant from the ASTRO Foundation, then known as the Radiation Oncology Institute (ROI), that aimed to develop a resource to manage acute and late radiation toxicity. The Foundation assumed responsibility for the RadOnc Toolbox and released the first version in 2016. Since then, the Foundation has continued to add resources and enhance the content. The redesigned RadOnc Toolbox released by the Foundation in 2023 is produced in collaboration with Red Canvas, LLC.

Verdict
The clearest difference is review sentiment: eLQ at 67% against RO Toolbox's 0%. eLQ also leads on iOS requirement (6.0 vs 15.6). RO Toolbox's advantage is rating (4.5 vs 4.0) and update cadence (every 3 months vs every 14 months). On price, ads, in-app purchases and monetization model there is nothing between them.

eLQ ships an update every 14 months, RO Toolbox every 3 months. The most recent releases landed on September 18, 2026 and June 1, 2026 respectively.
