Stress, anxiety, tension, brain fog, low energy — your body and mind are always sending signals. Aura helps you notice them, understand them, and act on them, a few minutes at a time. THREE REASONS TO INSTALL AURA: 1. A plan built around you Take a quick quiz and get a personalized path based on your goals and symptoms — calming an overactive stress response, easing tension, improving focus, or just feeling more like yourself. 2. 7-min guided exercises Daily exercises — breathing, somatic movement, nervous system resets — are built to fit into a real schedule, not replace it. 3. Daily lessons that actually stick Bite-sized, easy-to-follow education on stress, the nervous system, and mindset, so you understand the “why” behind every practice. Aura isn’t one technique — it’s a companion for your overall wellbeing, adapting with you as your needs change.

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.

Verdict
The clearest difference is ads: CellaLonga at none against Aura's shown. Aura's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (16.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
