Symptom log
Plainlog
A ten-second daily check-in for people living with a chronic illness. Record which symptoms were present and how much, plus sleep, energy and pain, then bring a clear one-page-per-month PDF to your next appointment.
Independent software company
Small, careful software for the records of everyday life.
Kehr & Co. makes focused apps for the things people are asked to keep track of: how they have been feeling, which medicines the household takes, and everything about a parent’s care. Each one keeps its records on your phone, asks for no account, and shows no ads.

Products
Family medication schedules
Pillfolk
One list of who in the household takes what, and when. Reminders on your phone, a record of each dose taken or skipped, and a printable medication list to hand to a doctor, a school or a pharmacist.
Caregiver binder
Alderbook
The binder for an aging parent’s care, kept on the phone that is always in your pocket: documents, medications, appointments and their questions, contacts, and who in the family is doing what, with a one-page summary for any doctor.
Spreadsheets
Ablehand
An assistant that works inside your spreadsheet, so you can get expert results without needing to know how.
Our apps help you log, record and organise information you choose to enter. They do not diagnose, measure or give medical advice.

Principles
Plainlog, Pillfolk and Alderbook are built to the same four rules. They are not settings; they are how the apps are made.
- Local-first
- Your records live on your device, not on a server of ours. The apps work fully offline, and what you write down stays where you put it.
- No account
- Open the app and start. No sign-up, no email address, no password to remember.
- No ads, no tracking
- No advertising, no analytics SDKs and no third-party trackers. You can export everything or delete everything from inside each app.
- One fair price
- No subscriptions. What an app costs is stated plainly, before you rely on it.

About
Kehr & Co. is a small, independent software company founded in 2026 by Dylan Kehr. It is the parent company of each of the products above.
We prefer a few well-made tools to a large platform. Each app does one job for one kind of person, does it quickly, and treats what you record as yours. When a feature would require collecting more about you than the job needs, we leave it out.
This website sets no cookies and runs no analytics or third-party scripts. Our host, Cloudflare, processes the standard request information needed to deliver the page.
