Good Tuner, Could be Even Better!

This tuner is just the best in terms of layout and simplicity. But what’s holding it back are two things:
1) There is no option to create custom tunings. This is a very easy feature to implement since the tuner already has all the chromatic notes available, just let the user decide how many strings they want the metaphorical instrument to have and then let the user pick the note / Hz of those strings
2) This app needs a better way to store or save favorite tunings instead of a single scroll list with no good way to jump to what you want. Maybe just a search bar would solve this?

Perfect + what would make this app better

Through my years (3 years) of playing guitar and mandolin I’ve struggled to find a perfect tuner; most of the ones I’ve used aren’t spot on to the note, can’t pick up sound, and have a terrible design. But fine tuner has a simple design with no complexity, and is able to pick up your instrument over others playing around you. And after a year of using this tuner, I think it’s safe to say that this is the tuning perfect tuning app.
One thing that I would love to see, is the l
“favorite” feature where you favorite your tuning so that way you can easily get to it instead of surfing through all the others. I often switch from open g, to standard, to dadgad, and many others and often find it time consuming to find the tuning I’m looking for. Although it’s not a puzzle to get to your tuning, it would be easier with the favorite feature.

Fairly impressed!

This app is perfect and is my preferred tuner. Well worth the inexpensive cost of purchase for the full app. Improvements suggested would be saving preferred instrument tunings to the top of the list, and adding additional tuning standards such as E4=333hz (whatever that would equate to with the A4) seems like it would be rather easy for a mathematical function to reproduce more settings... perhaps an variable slider with value inputs. Additionally, the dark theme is perfect in my view. Might be worth while to include some sort of linked information on when and how metal and nylon (and etc.) strings will likely break. Perhaps another reading on purchasing new strings and descriptions of various tunings links (their vibes, their feel, their usage, etc.)
