Splytlide is a bill splitting and invoicing application built using Ylide blockchain messaging infrastructure.
How to use it?
You can send an invoice, share it with the friends and request a refund of part of the funds (similar to Splitwise).
The application is well assembled technically, the code is clean enough, but there are a few technical troubles. A very interesting idea, but the app failed to launch during the test — it needs to be finalized.
