The principle

Create once, sell many times, with no stock or shipping.

The range

• Studies: exam schedule, revision tracking
• Finance: budget, expenses, savings
• Productivity: habits, goals, routines
• Bundles of several trackers

Channels

Etsy to be found, Gumroad and Ko-fi for direct sales, Amazon KDP for printed versions.

What I took from it

A generic tracker drowns in the competition. A specialised tool, like a dashboard for medical students, is worth far more: that’s what led me to My organiser and MedStudy Flow.
