Tonight's Moon: Phase Trackers & a Private Lunar Journal
Knowing what the moon looked like on a particular evening is either completely irrelevant or strangely important, depending on who you ask, and a decent moon phase tracker app makes it easy to check either way. I built one for iPhone that doubles as a private journal, and a lighter Chrome extension for glancing at tonight's phase without leaving the browser.
They're built for slightly different habits: one for a quiet nightly routine, the other for a quick check mid-browsing session.
A Moon Phase Tracker App with a Private Journal
A phase reading on its own is only half the picture — the more interesting habit is noting how a particular night felt and looking back on it later.
Luna Journal shows tonight's moon phase, a full month lunar calendar, and a quiet, private journal where every entry is stamped with that day's phase and zodiac sign. It's built for anyone who wants to note how a particular night felt rather than just what the sky looked like, kept entirely on the device rather than shared anywhere or backed up to a stranger's server.
Checking the Moon Phase Without Leaving Chrome
Not every check needs a full journal — sometimes you just want to glance at tonight's phase while you're already at your desk, without reaching for your phone at all.
Moon Phase Calendar tracks lunar cycles with a clear, browser-based calendar, giving you a quick way to check the current or upcoming phase without switching over to a phone. It suits a quick glance mid-task rather than the slower, reflective habit Luna Journal is built around in the evening.
The same information suits a phone screen at night and a browser tab during the day rather differently, which is why this stayed as two separate apps instead of being crammed into one. Use whichever fits the moment you're actually checking it in, or both, if the moon matters to you often enough to want both habits covered.
Frequently asked questions

Luna Journal is free and shows tonight's moon phase alongside a full month lunar calendar and a private journal stamped with each day's phase and zodiac.
Can I check the moon phase directly in my browser?
Yes — Moon Phase Calendar is a Chrome extension that tracks lunar cycles and shows the current phase without needing to open a separate app.
