What Apexhone does,
and how to start.
Five minutes to read. By the end, you will know whether this is useful for you.
What it is
A structured-thinking tool built for decisions that matter.
A blank page won't force clarity — structured questions will. We turn the judgment tools of Bezos, Munger, and Kahneman into specific fields you fill in, one at a time.
Then, months later, we remind you to verify what actually happened — what you predicted vs the outcome. Over time, your judgment fingerprint emerges: which biases you fall for, which frameworks work for you.
How it works
01
Name the decision
In a few sentences, capture what you are facing — the situation, the constraints, the options.
02
Pick a framework
Choose one decision framework from management, psychology, or finance — and work through its structured questions.
03
Come back and verify
Set a reminder. A few months later, log what actually happened. See your judgment improve, and your blind spots show up.

FAQ
You might be wondering
Is Apexhone free?
Yes. 10 core frameworks, decision logging, bias quiz, and option-comparison are free. Pro (NT$149/month, ~US$5) unlocks the full 27-framework library and the long-term Decision Pattern Map.
What's the difference between Free and Pro?
Free covers what you need day-to-day: log decisions, set reminders, verify outcomes. Pro adds analyses that only become meaningful with time — your bias map, prediction-accuracy by framework, annual review ritual.
Is my decision data secure? Where is it stored?
Data is stored on Cloudflare edge with encryption in transit and at rest. You can export everything as JSON or delete your account at any time. We do not train AI on your data.
How is this different from Notion or a journal?
Blank pages don't force clarity — structured questions do. We turn the judgment tools of Bezos, Munger, and Kahneman into specific fields you fill in, and remind you months later to verify what actually happened. A journal can't do that.
Do I need to use it every day?
No. This is not a habit-tracking app — it's a "open it for decisions that matter" tool. 5–10 uses a year, five minutes each, is enough to build your judgment fingerprint.
How do I pay? Refunds?
Pro is currently activated manually — pay and email invictnox@gmail.com to upgrade. Monthly plans can be canceled anytime; full refund within 7 days of first subscription if you are not satisfied.
