Blimbi vs YAZIO: documented fasting and nutrition 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 puts this difference in a six-product context. If you want a documented timer-first product rather than a broader diary, read Blimbi versus Zero. This is a comparison of documented product information, not an assessment of fasting efficacy, nutrition quality, or medical safety.

Who each app fits

YAZIO may fit a person who wants optional fasting plans inside a food-and-activity workflow. The sources describe meal timing and water reminders, visual history and trends, weight and body metrics, a food database, barcode scan, recipes and meal planning, and steps or workout inputs. Apple Health and Health Connect are described as free integrations, while additional named integrations are described for Pro. Apple Watch and partner wearables are also described. The stores mention mood and symptom tracking as Pro features, but that is product documentation, not a health evaluation.

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

No durable price is listed here. The records establish a free base product and paid Pro features, but not a stable amount. A seven-day Pro trial is documented as occasional and website-only, not a permanent app-store promise. Recipe totals also vary between storefronts, so this comparison does not use a fixed number. Verify your country, plan, trial, renewal, and cancellation screen at the point of purchase.

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.

Blimbi can export the journal as CSV. The iOS listing also documents widgets, Live Activities, Shortcuts, Apple Watch and configurable reminders; those references do not attribute Apple features to Android. Stages are educational guidance based on time, not body measurements. Review permissions and the privacy policy before enabling optional synchronization.

Method, sources, and update

This page uses Blimbi’s public App Store and Google Play listings plus YAZIO’s press material, fact sheet, Apple and Google listings, terms and privacy policy, supported-devices help, cancellation, deletion, and trial help. It includes only dated direct product facts and preserves uncertainty. For a more narrowly documented free timer and Coach distinction, see Blimbi versus BodyFast.
