Checkup Reminder Tracker

Opticians, doctors, dentists and every other checkup — tracked privately in this browser, with reminder emails you trigger yourself.

Everything is stored locally on this device only. Nothing is uploaded anywhere — use Settings → Backup to save a copy, or Restore to bring one back.

How to Use the Checkup Reminder Tracker

1
Set up once

The first time you open this tool it asks for your name, the email address reminders should go to, how many days' warning you want, and who you're tracking — yourself, a partner, kids. You can change any of this later from the gear icon.

2
Add a reminder — and backdate it if you're already overdue

Choose Recurring for anything on a cycle (Optician every 12 months, Dentist every 6) or One-off for a specific booked appointment. For a recurring reminder, the "last visit" date can be set in the past — if your last optician visit was 14 months ago on a 12-month cycle, it lands straight in the Overdue column the moment you save it.

3
Read the three columns

Overdue (past its due date), Due Soon (inside your warning window) and Upcoming (everything else). Nothing needs manual sorting — it moves itself as dates pass.

4
Log a visit when it happens

For a recurring reminder, "Log visit" updates the last-visit date and works out the next one for you. For a one-off, it marks the appointment done and files it under "Completed one-offs" further down the page.

5
Snooze if you're not ready to book yet

The small dropdown on each card pushes a reminder back a week, two weeks, one month or three months without losing the original due date.

6
Email yourself a reminder

Click "Email reminder" on a single card, or "Email me these reminders" in the banner to get everything overdue or due soon in one message. This opens a pre-filled draft in your own email app — you click send. A browser page on its own can't send email for you.

7
Back up before you clear your browser or switch devices

Settings → "Download backup" saves everything as a small file. "Restore from file" brings it back — on this device after a browser reset, or on a different device entirely. Restoring replaces whatever is currently stored.

Frequently Asked Questions

No — and no browser-only tool honestly can, since there's no server running in the background to send mail while the tab is closed. Instead, each time you open the tracker it shows what's due, and the "Email reminder" buttons open a ready-written email in your own mail app for you to send. The reliable habit is opening it every few days.

Yes, it's saved automatically in this browser's local storage and will still be here next time you open the page in the same browser on the same device. It isn't backed up online anywhere, so it won't appear on a different device or browser unless you use Backup and Restore, and clearing your browser data will remove it.

Yes, but each browser stores its own separate copy. Use Settings → "Download backup" on one device, then "Restore from file" on the other to bring the same data across. It won't stay automatically in sync between the two afterwards — you'd repeat that whenever you want them to match.

When adding a recurring reminder, the "last visit" date isn't locked to today — you can enter any date in the past. The tracker then works out the next due date from that real date, which means a checkup you're already behind on shows up as Overdue immediately, instead of you having to wait a full cycle for it to appear.

They're common general guidelines (e.g. dental checkups roughly every 6 months, optician checks roughly every 12) meant as a sensible starting point, not medical advice. Every interval is fully editable per reminder — use whatever your own doctor, dentist or optician actually recommends for you.

Not automatically — you'd need to re-add it, or restore from a recent backup if you have one. People and categories can only be removed while nothing is currently using them, which is a safeguard against losing reminder history by accident.

Disclaimer: This tool is a personal organiser for keeping track of appointments you've decided to book — it is not medical advice and does not set or recommend screening schedules. Reminder intervals are general defaults you can change, not clinical guidance. Always follow the specific advice of your GP, dentist, optician or other healthcare provider for how often you personally should be checked.
