Most weight loss approaches tell you what to eat and how much to move. Perpetua shows you the exact neural mechanism keeping the pattern in place — and what your brain actually needs to change it.

You've tried logging food. You've tried meal plans, challenges, apps that send you reminders, group accountability programs. Some worked for a few weeks. None of them lasted.
The standard explanation is that you lacked discipline. Or motivation. Or consistency. These explanations are wrong — and they're why the approaches built around them keep failing the same way.
Behaviour change failure is a neuroscience problem. Specifically, it's a problem of how your brain encodes, maintains, and overrides behavioural patterns at a mechanistic level.
The pattern keeping you stuck isn't a character flaw. It's a learned neural sequence with specific antecedents, consequences, and a function your brain is trying to serve. Address those — not the surface behaviour — and the pattern changes.
Every mainstream weight loss approach targets the symptom. Perpetua targets the mechanism. The methodology is drawn from peer-reviewed behaviour analysis (Watson & Tharp, 10th ed.) applied through a neuroscience lens developed across a decade in special operations and clinical settings.
Perpetua guides you through a structured behaviour analysis — the same methodology used in clinical and operational settings, adapted for daily self-directed use. You don't follow a generic protocol. You map your own pattern first.
Daily coaching prompts arrive as brief notifications — under 50 words, action-specific, routed to where you are in the process. Not motivational. Directive.
Start with the full Perpetua experience — no features locked, no prompts to upgrade. At day 14, you're automatically moved to the plan you chose. Cancel from Settings at any point.
All plans include a 14-day free trial. No charge until day 14. You will receive an email reminder 24 hours before billing begins.
Most apps give you a tracking tool and a target. The assumption is that if you track long enough and consistently enough, the behaviour will change. That assumption is wrong for most people — and when they fail, the app blames adherence.
Perpetua doesn't give you a target first. It starts with two weeks of structured observation because you cannot design an effective intervention until you understand exactly what the pattern is doing and why. The strategy comes after the analysis, not before it.
This is standard clinical practice in behaviour analysis. It has simply never been built into a self-directed app before.
That's precisely who Perpetua is built for. The pattern that hasn't responded to willpower, meal plans, challenges, and accountability programs is almost certainly serving a function that none of those approaches addressed.
The functional analysis phase is designed to surface that function. Once you know what your brain is actually using the behaviour for, you can design a replacement that serves the same function without the consequences. That's a very different approach to "try harder."
During the baseline phase (the first two weeks): approximately 3–5 minutes per observation, which you'll do 2–3 times per day when a behaviour occurs. Not a structured time block — observations happen in context, when the pattern happens.
After the baseline: a daily coaching prompt (under 60 seconds to read) and a weekly progress review (10–15 minutes). The process is designed to integrate into your existing day, not add a separate routine.
Yes. The A–B–C framework applies to any behaviour pattern — quitting smoking, building an exercise habit, procrastination, reactive emotional patterns, starting a business. The methodology is behaviour-category agnostic: the mechanism of pattern formation is the same regardless of the specific behaviour.
The landing page focuses on food and weight because that's where most people start. Inside the app, you select your target behaviour at the beginning and the process adapts accordingly.
Perpetua was built by Dr. Daniel Cooper — PhD researcher with a background spanning special operations and applied neuroscience, based in Brisbane, Australia.
The methodology is grounded in Watson & Tharp's Self-Directed Behavior (10th edition) — the definitive academic text on applied behaviour analysis for self-directed change — integrated with neuroscience frameworks from Dr. Cooper's research and operational work. This is not an interpretation of popular psychology. It's a direct application of peer-reviewed behaviour science.
Yes. Cancel from Settings inside the app at any point — one step, no confirmation prompts, no retention flows. If you cancel during your trial, you won't be charged. If you cancel after billing, you keep access through the end of your current period.
Transparency is non-negotiable: you'll receive a reminder email 24 hours before your trial converts to a paid plan.
14 days. Full access. No charge until you decide it's working. Start with understanding your pattern — everything else follows from there.
