Blimbi vs BodyFast: documented timer and Coach features

In 30 seconds

Direct verdict

Blimbi is published on iOS and Android. It is an intermittent-fasting timer with an editable journal and short reads. Its two states are Fasting and Eating: you choose when to start and stop, with no automatic starts or stops. New installs sign in with Apple or Google (the journal is end-to-end encrypted, so Blimbi cannot read it); installs from before version 2.4.0 can keep using it without an account. It has no ads. Public App Store and Google Play listings document these features.

The fasting-apps roundup gives the six-product view. If your question is about a documented free timer with Apple Watch or Google Fit support, compare Blimbi and Zero as well. These pages do not determine whether fasting, a schedule, or a product is medically appropriate.

Who each app fits

BodyFast may fit someone who wants official material describing a free fasting workflow and a distinct paid Coach layer. Its listings describe iPhone, iPad, and Android availability; free timer and reminder functions; more than ten plans; water and measurement tracking; an AI food scanner documented in the store release notes; food facts and tips; and several Coach features. Custom schedules, weekly personalized plans, recipes, community references, and challenges are described in the Coach context. The “team of experts” wording is preserved narrowly: credentials, response model, and clinical scope are not confirmed.

Blimbi focuses on timing and recording fasts. On iOS, optional diary logs for water, coffee, tea and other drinks, meal times, and body measurements (weight, height, waist, hip, chest, thigh and body-fat percentage) are off by default and enabled in Profile > diary settings. Meal entries record times only, without food items, calories or nutrition. Water, drink and meal-time entries stay on the device; weight and height join the end-to-end encrypted synced copy if you sign in and enable sync; other measurements stay on the device. The Android app records fasting logs only. These details were verified in the mobile source on September 29, 2026, rather than inferred from store listings. It does not track activity or symptoms or measure metabolism. It does not integrate Apple Health or Health Connect or offer AI or human coaching, recipes, community or challenges. Adding your clinician’s comment to a plan does not mean that Blimbi provides professional care.

How to read the verified matrix

The matrix separates present features, absent features and unconfirmed details. For Blimbi, “Yes” and “No” describe the current product, as documented in the stores and the mobile-source release ledger. “Not confirmed” means the reviewed sources do not establish a detail. A documented feature is not evidence of a clinical benefit and does not measure your metabolism.

Differences, privacy, and price caveat

Both apps have public store listings. Their scope differs: Blimbi concentrates on its fasting timer, journal and short reads, while BodyFast combines fasting with broader tracking and Coach features. BodyFast’s free feature material differentiates timer, reminders, water and other functions from Coach. The store release notes also describe an AI food scanner, while the feature material describes phase displays. Those descriptions are product features, not proof of nutritional accuracy, physiological measurement, health benefit, or clinical support.

Blimbi’s timer is free. Blimbi Plus lets you build custom weekly rhythms, add your clinician’s comment and prepare a draft you review before saving. Price and terms appear in the app. We do not compare amounts or promise a universal trial: check the purchase screen in your store.

No fixed price appears here. BodyFast’s official material says subscription prices can vary by country and purchase method, and the reviewed record does not establish a durable trial. Check local checkout, renewal terms, Coach entitlement, and cancellation instructions rather than relying on a screenshot or old offer.
