I prefer the old fashion way.
I use a diary, and write every impotant detail in it, and often the not so important things.
.
Any phone calls I have made (mainly to businesses & companies) it all goes into the diary. I even put the time of the call, how long I have waited to speak to someone, their name, what I have asked and responses and time the call was finished.
If ever there is an issue somewhere in the future, I can go back to get the info. I kept records of a lot of things.
It has come in very handy on many occasions. Once I produced my diaries as part of my evidence in a court case against an energy company, I had roughly two years worth of evidence written in my diary, dates, times, peoples name etc as well as other documents.
I easily won the case and was awarded damages.
I prefer my diary than using my phone as one.
