You train with a plan, so eat with one. The 8 Protocol is your food diary with a longevity focus: calories, macros and body metrics at a glance, without an account and without ads. LOG FOOD QUICKLY Search through Open Food Facts, a local staple food database (works offline) and a barcode scanner. Amounts in grams, millilitres, pieces, tablespoons or teaspoons. Values you already know go straight into the quick entry. Meal times optional. YOUR DAY AT A GLANCE Calorie ring and macro bars, swipe between days. Tapping the date opens the month at a glance: days within your target band are green. Calorie and macro goals from the goal calculator. Fiber as a daily total, with a note about missing values. Exercise without a watch: enter activity and duration, overwrite the estimated burn when you need to. Off by default. WEIGHT FROM APPLE HEALTH Your weight with its history from Apple Health. On request, The 8 Protocol writes calories and macros back to Apple Health (off by default). CALM OR COLORFUL Dark-first design, reminders (opt-in, off by default) and colorful meal categories you can switch off. Your profile picture sits at the top, next to the number of days you have tracked. YOUR DATA STAYS YOURS No account, no ads, no tracking. Your diary, profile and health data stay on your iPhone; the only exception is the optional photo estimate below. When you change phones, your data comes along in the iPhone backup. AND YOU TAKE IT WITH YOU The data export gives you your diary, water, sauna, fasting, custom ingredients and your daily goal as a ZIP with CSV and JSON. No subscription needed. WHERE THE NUTRITION VALUES COME FROM The nutrition values come from Open Food Facts (ODbL), from a local database with USDA reference values and from ingredients you create yourself. They are reference values without warranty. THE 8 PROTOCOL+ The subscription unlocks additional features: Nutrient estimate from a photo: photograph your meal, check the ingredients, and replace or add individual ones from the food search. Consent before first use, switchable off in your profile. For the estimate the photo goes briefly to my server, which does not store it, and on to an AI provider, which normally deletes it within 30 days. Up to 15 photos a day and 150 a month. Entering by hand stays more accurate. Fasting timer with automatic 16:8 window. 8 Score: a weekly overview of the criteria you met, 0 to 8 (not a health assessment). Weekly and monthly recap with averages and body metric changes. Daily report as a PDF: one day on a page. Plant diversity: a counter across 7 days, off by default (not a health assessment). Shortcuts, Action Button and Siri: log water, repeat a meal, start or end fasting, without opening the app. Weekday goals: a training day or rest day shifts your calorie and protein goal. Your own protein goal: set the factor per kilogram of body weight yourself. Water tracker: daily goal from your weight, set the factor yourself, optionally in Apple Health. Sauna tracker: the seven days of the week to tap, off by default (no target, no rating). Body fat percentage and lean body mass with history. Macro tips and protein distribution with evidence label. Create your own ingredients. The 8 Protocol+ is a subscription: Monthly: 4.99 US dollars per month. Annual: 34.99 US dollars per year, with a 7-day free trial. Prices in other regions may differ and are shown before you purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the term. You manage and cancel it in your Apple Account settings. The 8 Protocol is for users aged 16 and over. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://the8protocol.com/privacy/ Reference values without warranty, not medical advice, not an assessment of your health. The 8 Protocol is a self-tracking tool for general wellness. It is not a medical device and does not diagnose, treat, cure or prevent any disease. ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | The 8 Protocol+ (Monatsabo) | $4.99 | per month | | The 8 Protocol+ (Jahresabo) | $34.99 | per year | ## Version history (last 5 releases) ### 2.2.0 — 2026-08-26 New: log exercise sessions by hand. Pick the activity, enter the duration, and the estimated burn appears next to it. You can overwrite that value, for example with the figure from your fitness app. Made for everyone whose activity does not arrive through Apple Health. Off by default, switch it on in your profile. Exercise calories are deliberately not counted towards your calorie goal. Amounts can now be entered in millilitres, with a stored density for oil, milk, honey and others. 61 staple foods now carry a weight per piece: an egg, a slice of bread, an apple. You no longer have to estimate it every time. The photo estimate misses what lies under the topping less often, such as the slice of bread beneath the cold cuts. In the onboarding, technical terms have been replaced with everyday language. ### 2.1.0 — 2026-08-24 New: a sauna tracker. A row with the seven days of the week; you tap the ones you went. It shows the week of the day you are viewing, without a target and without a rating. Water and sauna now sit together below your meals, and both can be switched off individually in your profile, just like plant diversity. Sauna days are included in the data export. The calorie ring is a little smaller now, giving the day more room. ### 2.0.3 — 2026-08-23 The nutrient estimate from a photo now works more carefully behind the scenes. Names of recognised ingredients are checked more strictly before they reach your diary, and the data export is secured so that a spreadsheet cannot misread its contents. Nothing changes in how you use the app. ### 2.0.2 — 2026-08-21 You can now replace recognised ingredients instead of only removing them. A tap on Replace opens the food search, and the entry you pick brings its own nutrition values with it. If something on your plate is missing, you add it in the same step. The information about the nutrient estimate from a photo is now more precise. The consent screen says where the photo goes and for how long, and the privacy notice opens from there with a single tap. Because that text has changed, the app asks for your consent once more before the next photo estimate. The feature itself is unchanged. ### 2.0.1 — 2026-08-20 New in The 8 Protocol+: the nutrient estimate from a photo. Photograph your meal, the app suggests ingredients and amounts, and you check and change them before they go into your diary. The app asks you explicitly before the first use, because a photo of food allows conclusions about your diet. The photo is not stored anywhere, neither on my server nor in the app, and you can switch the feature off again in your profile with a single tap. An estimate stays an estimate: if you have the time and the opportunity, entering the ingredients by hand is more accurate. The app points this out on the capture screen. ## Apps similar to The 8 Protocol | App | Rating | Price | Category | | --- | --- | --- | --- | | [MITO LONGEVITY](https://appshunter.io/ios/app/mito-longevity/id6793368684) | — | Free | Health & Fitness | | [eoASSIST: Essential Oils Guide](https://appshunter.io/ios/app/eoassist-essential-oils-guide/id6761058419) | 5.0 (3) | Free | Health & Fitness | | [TASAGER Calorie Counter & Diet](https://appshunter.io/ios/app/tasager-calorie-counter-and-diet/id6473856690) | 4.9 (12) | Free | Health & Fitness | | [Meine R+V BKK](https://appshunter.io/ios/app/meine-r-plus-v-bkk/id1436004391) | — | Free | Health & Fitness | | [beneFit Fitness](https://appshunter.io/ios/app/benefit-fitness/id1608221114) | — | Free | Health & Fitness | | [SportBox app and move](https://appshunter.io/ios/app/sportbox-app-and-move/id6448397529) | — | Free | Health & Fitness | ## More apps by Nils Harder - [Kniekontrolle](https://appshunter.io/ios/app/kniekontrolle/id1210002709) - [Hausschatz](https://appshunter.io/ios/app/hausschatz/id6800693654) All apps by Nils Harder: https://appshunter.io/developer/1210002708 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
