Moonphase Filter: Love Test is one of those novelty apps that pops up on social media feeds and makes you curious enough to download it. It's essentially a fun, astrology-adjacent filter tool that uses the current moon phase to generate a compatibility score between you and your partner or crush. You can find it on both Google Play and the App Store, and it's free to download, though there are in-app purchases for extra reports and ad removal. After launching it for the first time, the interface feels pretty straightforward—just enter two names and birth dates, and the app does its thing. The first impression is honestly a bit playful, with a dreamy night-sky background and soft fonts, which fits the whole moon theme. It's not a serious love test, but it doesn't pretend to be.

Once you start using it, the experience is mostly tapping through a few screens. You pick the relationship type—romantic, friendship, or even self-reflection—and the app pulls up the moon phase for that day and calculates a percentage match. The animation that shows the moon glowing while it processes the result is a nice touch, if a little slow. I found myself swiping through different dates just to see how the score changed, and the app keeps a short history of past readings, which is handy. The onboarding is basically non-existent, which is fine because there's not much to learn. A small tip: if you want to avoid the occasional ad popping up mid-result, you might want to buy the ad-free version, but the free one is still usable. The only confusing moment was when I tried to share a result—it directed me to save a screenshot rather than sharing directly, which felt like an extra step.

After a few weeks of poking around, I'd say this app is really for people who enjoy lighthearted, low-stakes fortune-telling or moon-phase aesthetics. It's not a deep relationship tool, but it's fun for couples looking for a silly conversation starter or for someone who just likes checking their “cosmic compatibility” with a friend. Compared to apps like The Pattern or Co-Star, which dig into full natal charts, Moonphase Filter is much simpler and less serious. It doesn't provide any breakdown of why the score is what it is, which can feel shallow after a while. I kept it installed because it's small and quick to open, but I could see someone uninstalling it after a week if they wanted more substance. Overall, it's a cute gimmick, not a daily driver.

• 🌙 Moon Phase Matching: Unlike typical love calculators that just use names or numbers, this app actually factors in the current moon phase (new moon, full moon, etc.) to influence the compatibility score. It feels more dynamic than something like Love Tester because the result changes based on when you check it, making it a bit more interesting over time.
• 🌟🌟 Relationship Variety: You're not stuck with just romantic pairings. The app lets you test compatibility for friendships, family, or even self-reflection, which is something apps like Crush Calculator don't offer. It gives a broader, less awkward way to share with friends.
• 📊 Visual Moon History: The app keeps a log of past moon phases and your scores, so you can see patterns over time. This is a standout feature because most similar tools only give a one-off result, whereas this one lets you track “luckier” days or phases.

• ✨ Very easy to pick up: You can get a compatibility reading in under 30 seconds. Compared to Co-Star, which asks for detailed birth times, this is much faster and more casual.
• 🎨 Appealing aesthetics: The night-sky theme and moon animations look polished. It's more visually pleasing than The Pattern's dense text blocks, which makes it feel lighter and less overwhelming.
• 🔮 Good conversation starter: Perfect for sharing with a partner or friend for a laugh. It's less serious than other apps, so it avoids awkwardness.

• 📉 Shallow results: The compatibility score feels random and isn't explained. Apps like The Pattern give detailed personality insights, but this just shows a number and a short sentence.
• 🔄 Repetitive quickly: After a few checks, the novelty wears off. There's no daily content or evolving features like in Co-Star, so you might lose interest within days.
• 💸 In-app purchases pushy: Some additional reports are locked behind paywalls, and the ad removal fee feels high for such a simple app. Free versions of similar apps have fewer interruptions.
