Blimbi vs Simple: documented program and data 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.

Use the fasting-apps comparison for the full six-product context. If a more general food diary, wearables, and fasting-plan mix is what you need, the Blimbi versus YAZIO comparison offers a useful contrast. These pages compare documentation, not clinical suitability, safety, or health outcomes.

Who each app fits

Simple may fit a person looking for a product that officially describes a personal program, meal plans, food tracking, water tracking, education, and an AI coach. Its Premium information describes progress tracking and AVO, while privacy material identifies food and water tracking as core app features. This does not establish human coaching, a free timer, wearable support, a particular price, or the exact free-plan boundary. The reviewed pages also say that billing and purchase offers vary, which makes a permanent price claim unreliable.

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 product documentation. Blimbi focuses on a fasting timer, an editable journal and short reads, without coaching, food-item logging or calorie counting. Simple’s materials describe a program that extends beyond a fasting timer into meal planning, food logging, water tracking, education, and AI coaching. Describing those features is not a claim that the program produces a particular health, weight, or behavior result. The sources do not establish clinical supervision or a medical service.

There is no fair durable price comparison. Simple’s own material warns that purchase-time billing periods and offers vary. The research record intentionally omits an amount rather than presenting a transient offer as a standard price. Check the exact storefront, renewal terms, cancellation path, and country-specific conditions before purchasing.

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.

Method, sources, and update

The comparison uses the Blimbi public App Store and Google Play listings and Simple’s privacy policy, terms, personal-program help, Premium FAQ, cancellation and deletion help, and listed storefront records. It includes a fact only where a dated official source supports it, leaves gaps visible, and excludes outcome claims. Read Blimbi versus Fastic if community, challenges, and integrations are more important than a personal program.

Competitor sources retain their September 2, 2026 review; Blimbi’s store evidence was updated on September 28, 2026 (UTC). Refresh policy, billing, cancellation, and store details before relying on this page. The update note should retain “Not confirmed” unless a dated public source changes the evidence.
