## What is String Tension Calculator?

Our guitar string tension calculator app takes the guesswork out of tuning your guitar by providing precise tension calculations in pounds for each string. The app also includes a color-coded system, with "yellow" indicating light tension and "red" indicating heavy tension, making it easy to see the difference between strings. Plus, with the option to choose strings with the same tension, musicians with multiple instruments and tunings can quickly find the perfect string set to achieve consistent tension across all their guitars.

### 3/5 — Ok, could be improved

*2024-01-06*

This app is a good effort but I think it could be improved.

The scale length adjustment only allows for going up/down by 0.1 of an inch. This means that the Gibson scale length of 24.75” cannot be selected, only either 24.7 or 24.8. 

Also, the gauge selections jump between values, e.g. I can select 0.045” or 0.047”, but not 0.046”. The difference in tension between 45 and 47 thou’ is large - 45 thou’ at standard pitch E is 17.5lbs, 47 thou’ at the same pitch is 19.3lbs. 46’ thou would be somewhere between, but it isn’t shown.

For the above reasons the app is not accurate enough. I don’t understand why it has these oversights - a huge number of guitarists play Gibsons, and 46 thou’ is a very common gauge, included as standard in e.g. string sets by Ernie Ball, D’Addario and others.
