Understand. Support. Don’t obsess.
Build a short plan for your day. Record what you noticed without turning it into a hormone explanation.
Free to use. No email required. For adults seeking everyday structure—not a cortisol test or treatment.
Daily tools · Free to use
Plan one small block of time. Record what your day felt like. These tools do not estimate cortisol or promise health outcomes.
Choose a focus and an available time block. Get a simple plan you can adapt to your circumstances.
A planning aid, not a treatment protocol. Choose activities that fit your abilities and any professional advice you already follow.
Record sleep duration and how your day felt. Start with observation, not a hormone explanation.
No entries yet. One observation is a useful start.
Entries are not sent to us by these tools. Changes in these observations do not establish changes in cortisol.
Use with awareness
Keep the purpose practical and the interpretation modest.
Choose morning, evening or a daytime pause. The 5-, 10- and 15-minute options allocate the time you selected; they are not treatment doses.
Record sleep duration, perceived energy, perceived stress and one habit. An entry describes your experience; it does not establish its medical cause.
Read your notes as observations. Different days do not demonstrate a change in cortisol. Persistent or concerning symptoms deserve professional evaluation.
Your entries · Your choice
By default, entries stay only in the current page session. Reloading or closing the page discards them.
If you select “Keep entries in this browser,” the journal uses browser storage on this device. It is not encrypted, is not a secure medical record and is not synced across devices.
A CSV download creates a file on your device. Store it appropriately, especially on a shared device.
These tools do not send journal entries to us. The website also uses Google Analytics and has Google AdSense code installed. External fonts and links involve requests to third-party services. See the Privacy Policy for details and privacy choices.
The new entry replaces that date’s existing entry. The journal keeps one observation per date.
Delete an individual entry or use “Clear all entries.” Unchecking the browser-storage option removes the stored copy while keeping the current entries in the open page.
You can continue with entries in the open page. If the journal cannot save to browser storage, it displays a message. Do not assume entries were saved. Download a CSV if you want to retain a separate copy.
The tools do not measure cortisol or establish hormone changes. They organize time and observations. They do not diagnose or treat endocrine conditions.
A deeper, organized path
The optional Core Guide, three System Tools and Audio Companion Series organize the educational material. You can keep using these free tools without buying.
