If you remember this product exists the next time you're measuring than yes, it might be useful. I use my notes app to jot down field measurements all the time and it works well. Simplicity can be nice up until the point of too much fragmentation.
There is a difference between straight text and spreadsheets. I also like notes, but numbers are just easier to process mentally in tabular form. If they weren't spreadsheets would have next to no value.
If I use a product and find it handy and convenient I'll remember to use it next time. Likewise, if I use a product and find it obtuse and makes a simple task harder than it needs to be, I'll remember not to use it next time.
If I need to jot down a quick note, I wouldn't use a word processor with all the inane amount of options. I would use a simple note app because all those word processing options serve no purpose and makes the simple task I'm trying to complete harder then it needs to be. Simplicity is a very convenient feature.
