For people who've quit every productivity app
You've downloaded the apps. Used them for a week. Quit. Felt bad about it. That cycle isn't a you problem — it's a design problem. Marvin is the first app that asks why you quit the last one, then builds something different.
Sound familiar?
Habitica, Streaks, MyFitnessPal, Zero — you've tried them all. The first week feels great. By week three, the notifications are off and the app is buried in a folder. It's not your fault. Those apps track what you do. They don't know who you are. They can't tell when you're slipping. They just sit there, waiting for you to show up. And when you don't, nothing happens.
The real reason they didn't work
MyFitnessPal is a calorie counter. It doesn't know why you overeat. Streaks is a checkbox app. It doesn't know your energy crashes after 3pm. Notion is a blank canvas that takes 10 hours to set up and 6 days to abandon. These apps give you a place to write things down. They don't build you a plan, adapt to your life, or notice when you're slipping. The gap between knowing what to do and actually doing it — that's a systems problem. Not an app problem.
Marvin is different. Here's why.
Say 'remember: my knee hurts.' Next time you ask about workouts, the AI has that context. It won't ask you to explain your situation every time. It's not perfect memory — but it's more than any other app gives you.
Miss a few days? Marvin looks at your last two weeks and tells you what happened. It doesn't guilt you. It doesn't reset your streak to zero. It just says 'here's the pattern I see' and asks if you want to adjust.
One click and Marvin reads your week and writes you a coaching report. What worked, where you dropped off, and one specific thing to change. Not a chart. Actual advice.
Check off a workout and see a science fact about progressive overload. Complete a fast and learn what's actually happening to your body. 60+ facts from peer-reviewed research, surfaced as you go. Not a content library — just a sentence when it matters.
Each module connects to a skill tree with curated resources — videos, articles, podcasts — organized by topic. Track what you've learned. It's a learning path, not just a checklist. 25 skill nodes and growing.
Workouts, fasting, sleep, books, meditation, supplements, journaling. Pick what you track. Ditch what you don't. No 200-feature setup weekend required.
The app graveyard on your phone
Your workout app doesn't know you're fasting. Your habit tracker doesn't know you slept 4 hours. Marvin puts it all on one dashboard — so you can actually see how everything connects.
Fair warning: Marvin isn't going to out-feature Strong at gym tracking or MyFitnessPal at food databases. What it does is put everything on one screen with an AI that sees the full picture. If you need a specialized deep tool for one thing, keep it. But if you're tired of juggling 5 apps that don't talk to each other — one dashboard, one check-in, $10/month.
No setup weekend required
Marvin asks what you want to track, what's failed before, and how much time you actually have. 2 minutes. No account needed.
Workouts, nutrition, fasting, journaling, sleep — configured from your answers. No setup guide. No blank page staring at you.
Check off what you did each day. Marvin tracks your streaks, detects patterns you would have missed, and generates your weekly coaching report on demand.
You've skipped workouts 3 days in a row — that's usually when the cycle starts. Your note says your knee's been bothering you. Maybe scale back to upper body this week and see how it feels?
Why this exists
I tried Notion, Finch, MyFitnessPal, Google Tasks. Most of them I installed and forgot about. Notion was the one I spent time with — for about two weeks. Then I found Claude Code, built my own system, used it every day for weeks, and realized — this is the product.
I'm not going to sit here and tell you Marvin will make you productive. That comes from within. But if the drive is there and you keep running out of a working system, that's what this is for.
Some modules are still being built out. It's a real product made by one person. If something's broken, tell me — I'm the one using it too.
One price. Everything included.
No feature gates. No upsells. No “premium tier.” You get the full product from day one.
