We'd like to one day (and this would be the right time to introduce user fingerings and such), but currently, with a software development team of one, we have too many more urgent priorities, so it's not in our short/mid-term plans.
@paul-flute Hi Paul, the Sylphyo does not contain the listed chemicals phtalates, DEHP or BPA. The Sylphyo body is made from ABS plastic with a V0 treatment for uninflammability. The mouthpiece is made from food-grade ABS plastic. The Sylphyo has also been approved by the FCC. You can find the documentation for this online.
