First release.
Tonight's Moon, drawn by the shadow that crosses it. Offline, no account.
Moon tells you which Moon is up tonight. It opens straight onto it, drawn the way you see it from the window: the lit part, the shadow crossing it, and the faint grey of the rest of the disc — the light the Earth throws back at it. • The phase in words and in numbers: Waning crescent · 24% lit · 22.3 days old • The disc is drawn, not photographed: the terminator is the right curve, not half a circle • Next full moon and next new moon, with date, time and days to go • Next solar and lunar eclipse, with the kind spelled out: total, annular, partial or penumbral — and a note that the times are for the whole Earth • Drag to travel through the lunation: the Moon waxes and wanes under your thumb, with a tap of haptics at every phase you cross • Double tap to come back to tonight What Moon does not do: • no account, no sign-up • no location, no network: the phase is computed on the phone, so it works up a mountain, on a plane and with mobile data off • no servers of ours: there is nothing to send The maths follows Jean Meeus's astronomical algorithms: the instants of new and full moon land on the right minute, and automated tests check it before every release. Permissions: Internet (ads only) and vibration (the haptic feedback). The app is free and paid for by ads: a banner at the bottom, away from the controls, and an occasional full-screen ad only after you got your answer.
