Tracking question

I am a very very small fish with less than £100 invested in cryptocurrency.

I was just wondering how do you all keep track of how much you've spent and at what price, so as to accurately work out profit/losses?

I.e say you bought 0.5 Lite coin when it was $60, then 1 Lite coin when it was $40 and now it is worth $55.

Is there an app or are you all Excel wizards?

Surely after you've bought loads over an extended period of time at different prices it gets very confusing.
