Yeah the dots look fine (and I don’t mean to turn the dots off entirely).
As an example (in case I’m not explaining myself well). If you are near the top (say the About Us section) and you scroll down with your finger on the left side of the screen (away from the dots), it will scroll as normal and the blue/active dot will follow you along.
However, if you scroll with your finger on the right side, close to the dots, wherever my finger first taps to start the scroll motion, that dot gets highlighted in white and the text of that section pops up (and it stays highlighted for me when my finger comes off). It’s probably not a big deal but it could possibly confuse the user as to what section they’re in.
*Disclaimers: 1) I’m on a iPhone 6Plus, which seem to be a weird in-between sized screen and probably aren’t the best testing devices. 2) This is admittedly a ‘not seeing the forest for the trees’ piece of feedback. I’m sure a typical user will be able to know where they are on your ‘dot’ timeline. Just something I noticed.
