Over the years my wife and I have been sharing lots of information via Whatsapp some of which we need for tracking purposes, the most common being weekly metrics from a business operations where I am a silent partner but key stakeholder

One neat trick that I discovered from a friend, I have forgotten who, was to leverage Whatsapp groups as a record keeping tool, this group only has the 2 of us, is named Farm Finances, and only contains the information we need to share with regard to the specific topic

Try this for your next business endeavor, wedding, construction activities, long or short running project whose records you do not want to have across the noise of day-to-day communications as you prepare to move this into a more formal tool

As I wrote this I figured out that you can also do the same for keeping notes for yourself, to-do-lists, project reminders etc
