What's on the map

Your calendar keeps meetings. Trailmark keeps the policy number, the cabin wifi, the LLC filing that comes back every March, and the note on how you did it last time.

NotesPages you'd hate to lose

Where the will is, the insurance policies, the cabin wifi. Markdown pages you can search from any device.

MarkersDates that come back

Every year, quarter, month or season, or once. Each carries a note on how you handled it last time.

TrailsWhere they live

House, Family, Vehicles, Taxes, the LLC. Like notebooks, and one can be shared with someone for free.

Done this year. Back on the trail next year.

Checking off a marker doesn't delete it. Each time around is its own stop, and the marker keeps what happened every time.

Dec 1Coming upA heads-up, not a nag

A month out, then a week out. Monthly bills only get the week.

Dec 3StartedYou're on it

Opened the county site, waiting on the eCheck. Reminders go quiet.

Dec 4DoneClosed for this year

Add a line: "Paid by eCheck, confirmation in email." That's next year's instructions.

Same marker, fresh year, with every past year underneath.
