All of our spreadsheets do not require any Excel or programming skills to use and are designed with the novice-user in mind.
Our no-subscription business model is based on providing customers with the tools, knowledge and education to maintain and customize their own logbook, specific to their needs. We do expect you to read fully and be able to follow instructions from our Operations Manual.
Cells containing complex algorithms are locked to prevent accidental modification to formulas. Advanced Excel users may request access to customise the logbook further.
