Symptoms: Improve activity scale visualization

[samanthar8]

How it works now

• Users rate a symptom's activity on a five step scale, represented by a smiley face and four squares
• There are hover tooltips, but on iOS, these are are only visible after touching one of the options
• If a square is selected, that square and all squares to the left of it fill in with a random color
• The smiley face only fills in if it is selected

User story As someone with a chronic illness, who is trying to track their health in the Flaredown iOS app, I would like to rate my symptoms' activity without confusion. The scale is confusing because:

1. The rating options don't have an explanation, so I don't know what the rating options are before I touch one
2. The smiley face doesn't match the square pattern, so I didn't think it was a rating option
3. The smiley face doesn't match the color pattern, so I didn't think it was a rating option

How it should work - TO BE DETERMINED

• The scale should still be the standard 1-5 symptom activity scale (note: does this have a name???)

Hey guys! I do think we can improve this UI, but we need a clearer problem statement in order to make the right changes.

Additionally, here's some important context about the current implementation:

The scale is based on the standard 1-5 symptom rating scales used in most self-reported disease activity indices. This helps our data to be more directly compatible with existing disease activity measures.

Colors are assigned when a trackable is created and kept consistent wherever the trackable appears in the application which makes it easier to identify across contexts.

@lmerriam I narrowed down the issue and edited the original comment-- this is now specifically addressing the visualization of the scale's options.

This type of scale is typically called a "Likert" scale. It's not specific to disease activity questionnaires, but it is typically the scale used for symptom severity on those measures.
