One ledger for your whole life
Problems resolved.
Opportunities taken.
Best Life keeps a running ledger of what's wrong and what's possible — across your money, health, legal matters, relationships and work — and walks each item to done.
How it works
Evidence in. Resolution out.
Everything that lands in your life is evidence. Best Life catches it, decides whether it matters, files it where it belongs, and helps you act — with the AI you choose doing the heavy lifting and you giving the final word.
Capture the evidence
Email, messages, voicemail, calendar and files flow in through your own channels — gRPC to etcd for the envelope, Jotta for storage, Hetzner for the server. You own the pipe.
Classify it
Checked against your adversaries and champions lists, read for intent, or flagged by you: every item becomes a problem, an opportunity, or a quiet archive.
Put it in context
The item is restated in every domain it touches and joined to its story — a one-off, or the next chapter in an ongoing thread that can span many adversaries or champions at once.
Resolve or exploit it
In the connected domains your AI researches the story, drafts a strategy and prepares the outputs. You approve delivery — and it's sent to the adversary or champion on your behalf.
Two colors, one ledger
Everything is a problem or an opportunity.
Problems
An adversary writes. A deadline lands. A bill is wrong. It becomes a problem story — threaded to everything related, given a strategy, and walked to closed. Nothing slips because it was in the wrong inbox.
Opportunities
A champion reaches out. A door opens. A report is ready to import. It becomes an opportunity story you can act on — with research and a draft ready — before the moment passes.
Groups & domains
Five groups. Forty-two domains. One place.
Every domain keeps its own evidence, tasks and sources — email, calendars, bank feeds, court listings, health data — connected only when you say so.

Deterministic where it can be, AI where it counts
The app does the work. You approve it.
Some steps are deterministic — the app simply runs them. Others hand off to the AI you've chosen, with clear placeholders for exactly where it takes over. You pick the model and the sources; nothing leaves without your say-so.
Research
In the connected domains, the AI gathers the facts of the story — the history, the parties, the stakes.
Strategy
It proposes a way to resolve the problem or seize the opportunity, grounded in the connected domains.
Draft & send
It drafts the outputs for review. You approve delivery, and the app sends the final word to the adversary or champion.
Privacy
Private by architecture, not by policy
On-device first
Your ledger lives in the app on your Mac, iPad and iPhone. AI runs on Apple's on-device models unless you choose otherwise.
The confidential lock
Tax, legal, medical, mind and family domains are locked: their data never reaches a cloud model, whatever else you enable.
Your sources, your choice
Connect a bank, a court listing service, HealthKit or just a folder of statements. Every connection is opt-in, per domain.
Your storage, your server
Evidence is archived, backed up and synced to your own Jotta storage over your own Hetzner server. We never hold your data — because it was never ours.
Under the hood
Built like a proper inbox — then some.
Threaded conversations
Replies collapse into one story instead of scattering across your list.
Sent copies that thread
What you send is stored beside what you received, in the same thread.
Adversaries & champions
Named lists that instantly flag incoming evidence as a problem or an opportunity.
Stories & threads
Related items combine into a running narrative across the domains they touch.
The therapy assistant
An always-on assistant beside every item to research, draft and talk it through.
Every channel in one inbox
All your accounts and mailboxes gathered into a single classified view.

FAQ
Questions, answered
What is Best Life?+
One ledger for your whole life. It catches the evidence that lands on you, decides whether each piece is a problem or an opportunity, files it across the domains it touches, and helps you resolve or seize it — with the AI you choose and your final approval.
How does my evidence get in?+
Through your own channels — email, messages, voicemail, calendar and files — over infrastructure you control: gRPC to etcd for the envelope, Jotta for storage, Hetzner for the server. You connect sources per domain, opt-in only.
Who can see my data?+
You. Your ledger lives in the app and syncs to your own storage. Confidential domains — tax, legal, medical, mind and family — never reach a cloud model. MobiCycle never holds your data, because it was never ours.
Can I use my own AI?+
Yes. You choose the AI as well as your sources. Deterministic steps run in the app; where a step needs a model, it hands off to the one you've picked, with clear placeholders for where it takes over.
Is there a free plan?+
No. We don't monetise your inbox with ads or data, so Best Life is funded by the people who use it. That keeps it on your infrastructure and out of the surveillance business.
What platforms is it on?+
The web app is live now in any browser. Native macOS, iPhone & iPad apps are in progress, with Windows, Linux and Android to follow.
