Sarah Petersen
Lead Reviewer
Sarah Petersen has spent the last seven years reviewing consumer software, with a focus on how subscription pricing and feature gating reshape app value over time. She started Calorie App Directory in 2024, after a decade of personal MyFitnessPal use ended with the 2024 barcode-scanner paywall. The site grew from one annoyed essay into a full directory because it became obvious that there was no resource that compared today's calorie-tracking apps on what people actually use them for, including the ones the apps changed last year.
