CellaLonga

Fasting isn't a diet. It's your longevity lever — measured honestly, owned for life. CellaLonga follows your body through the real metabolic journey of a fast: fed, glycogen, the metabolic switch, fat-burning, ketosis, autophagy, and deep autophagy — rendered as a living ring, not a countdown timer. THREE LAWS OF HONESTY Most fasting apps blur the line between what's known and what's guessed. CellaLonga never does: • Estimated, refined, and measured are always labelled — never confused. • Autophagy is always shown as an estimate. No consumer device can measure it directly, no matter what other apps claim. • Ketosis is the only stage that can become "measured" — and only if you log a real ketone reading. Every source is cited, with its caveats. YOUR OWN MIRROR See honest, non-causal correlations between your fasting windows and how you actually feel, sleep, and recover — never a single statistic without the data behind it, never a claim before there's enough of it. LONG FASTS, DONE RESPONSIBLY 24 to 72-hour fasts come with a real safety brief — hydration, warning signs, how to break a long fast gently — not just a longer timer. OWN IT, DON'T RENT IT One purchase unlocks full sources, measured mode, long fasts, your complete mirror, and unlimited history. No subscription. No guilt quizzes. No countdown pressure. PRIVATE BY DESIGN CellaLonga has no backend, no account, and collects nothing. Apple Health connection is entirely optional and only enriches what already works from a simple daily log. CellaLonga is informational only and is not medical advice. Consult a clinician before attempting extended fasts, especially if you take medication or have a medical condition.

Your workout is ready today, your way, and it adjusts every week based on the effort you logged. Orkadu brings together what usually lives scattered: the training plan, the load log, your latest lab results, check-in measurements, what you report each morning, and your progress over months. FOUR WAYS TO START TRAINING Generate a plan with AI from your profile, build one from scratch, start from a ready template, or import the plan your personal trainer wrote (PDF or photo). You choose. The library has 800+ exercises with visual demos. TRAINING THAT ADJUSTS EVERY WEEK After each gym or home session you mark how it went: light, right, heavy or failed. Next week's loads change because of it. That is the autoregulation no spreadsheet does on its own, whether you lift for strength, size, or to leave the couch safely. CAN I PUSH TODAY? The home screen answers before you ask: today's readiness and this week's load come from the sessions you logged, with the real duration of each one. Missing data? The app says so. It does not make things up. THE FIVE-TAP JOURNAL Every morning: sleep, stress, pain, alcohol, water. Fifteen seconds. It is what no watch measures, and it sits next to the numbers your watch does measure. KADU TALKS TO YOUR DATA Kadu is Orkadu's assistant. Ask about today's workout, the knee that bothers you, or the load that will not go up: it answers with your numbers in hand and suggests the next step. Every week it writes your report with what changed, from facts already in the app. AI READS YOUR LABS, AND YOUR TRAINING TAKES IT INTO ACCOUNT Upload the lab PDF (or a photo of the sheet). Markers become visual reference rulers, you follow each one over time, and your training accounts for what the labs showed. Labs are optional: without them, your plan still comes from your profile. LOGGING WITHOUT FRICTION Log workout, set and load in a few taps, with session time counted for you. Running, walking and cycling take distance, and pace is calculated. Check in with weight, measurements and progress photos: the side-by-side comparison shows what the daily mirror hides. PROFILE, CHALLENGES AND COMMUNITIES You decide whether you show up. The profile is optional: nickname, level and achievements. Never labs, weight, measurements or photos. Invite your training partners to a challenge scored by sessions, or join a community, by invite or open, with a consistency ranking. You agree on what is at stake; the app keeps score, the settling is yours, outside the app. Every post and every member has two-tap reporting and blocking, and moderation responds within 24 hours. For adults 18+. YOUR DATA IS YOURS Health data encrypted (AES-256). Photos have location stripped before storage.

Verdict
The clearest difference is update cadence: Orkadu at every 11 days against CellaLonga's every 2 months. Orkadu also leads on iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
