Melbourne app developer Long Zheng is on a mission. To "make myki great again".

To which some might reply: was it ever great?

App mypal lets you top-up myki on your mobile.

But Mr Zheng is earnest, and genuinely wants to help. This week he released a free app that solves a key gripe for myki users: topping up using a mobile phone.

Despite it being 2017, Public Transport Victoria does not offer a mobile-friendly website for commuters to top up myki cards. The existing website forces users on phones to awkwardly tap, zoom, and input text in tiny fields.
