Launching soon page for upcoming “subscription tracking” iPhone app titled ‘Billy’. The screenshot preview is clear and I quite like how the mobile adaption loses the hand.
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 12 October 2015.
