TDF Calc vs ASCO Guidelines
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TDF Calc
This app calculates the biologically effective dose (BED) for radiation therapy fractionation regimens. It allows for comparisons of different treatment schedules and helps determine dose per fraction based on desired treatment duration.
- Linear-quadratic (LQ) method implementation
- Biologically effective dose (BED) calculation
- External beam radiation therapy (EBRT) fractionation
- Low dose rate (LDR) brachytherapy
- Permanent implant brachytherapy
- Dose per fraction calculation

TDFCalc is an application which implements the linear-quadratic (LQ) method for comparing the biologically effective dose (BED) of external beam radiation therapy (EBRT) fractionation regimens as well as low dose rate (LDR) and permanent implant brachytherapy treatments. It calculates BED for a given alpha/beta ratio as a function of the dose per fraction and number of fractions for EBRT, and initial dose rate for brachytherapy. For a predetermined BED, the app solves the quadratic equation to calculate dose per fraction as a function of the number of fractions desired. This enables quick comparison of modified fractionation regimens (e.g. hypofractionation or compensating for missing treatment fractions) vs a conventional and/or originally intended regimen.
ASCO Guidelines

The ASCO Guidelines app is your go-to tool for implementing guideline recommendations into practice. This user-friendly app provides health care providers, patients, and caregivers with the recommended cancer care options for a variety of cancer types. It also includes interactive tools to inform treatment decisions at the point of care, thus increasing the quality of care provided to patients. The ASCO app is free to members and nonmembers, kept up to date, and will continue to grow as more guidelines and tools are added.

Verdict
The clearest difference is review sentiment: TDF Calc at 100% against ASCO Guidelines's 57%. TDF Calc also leads on rating (5.0 vs 4.8). ASCO Guidelines's advantage is update cadence (every 5 months vs every 67 months) and ratings volume (261 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
