Depression Test is a mental health screening tool made by Inquiry Health LLC, available on both Google Play and the App Store. It's exactly what it sounds like — a self-assessment app designed to help people check in on their mental state using standardized questionnaires. You'd download this if you're feeling off but aren't sure if it's just a rough patch or something more serious. After installing it (which is free, by the way, and has been downloaded over 500,000 times according to the Play Store), you're met with a clean, no-nonsense interface. No flashy animations or overwhelming colors, just straightforward questions and a progress bar. That first impression is actually pretty important for this kind of app — you want something that feels clinical but not cold, and they nailed it. There's no registration required to start, which removes a huge barrier for people who might be hesitant about sharing personal data.

Once you get into the app, the experience is surprisingly smooth. You're guided through a series of questions based on the PHQ-9 scale, which is the gold standard for initial depression screening. The onboarding is minimal — you literally just start answering. Each question asks about how often you've experienced certain feelings over the past two weeks, with options ranging from "not at all" to "nearly every day." It took me about five minutes to complete the full assessment. What I appreciated was that you could go back and change answers if you realized you misclicked, which is easy to do when you're rushing through emotional topics. The app saves your progress automatically too, so if you get interrupted, you don't lose everything. There are no ads popping up mid-questionnaire, which would've been absolutely jarring given the subject matter. The only minor hiccup I noticed was that the text felt a bit small on my phone screen, but that's probably more of a device issue than an app issue.

After using this for a few weeks, I can see why it has its audience but also why some people might pass on it. The app gives you a score at the end with basic context — mild, moderate, or severe — and encourages you to share results with a professional. That's its strength and its limitation. If you're someone who's already in therapy or seeing a psychiatrist, this is a useful tracking tool between visits. If you're completely new to mental health care, the lack of actionable next steps or crisis resources might leave you hanging. Compared to more feature-packed options like Moodpath or Daylio, this feels deliberately stripped down. That's not a bad thing — some people get overwhelmed by too many features — but others might find it too bare-bones for daily use. I ended up keeping it installed because it's simple to check in once every couple of weeks, but I can imagine someone deleting it after their first assessment unless they're specifically looking for long-term tracking.

• 😊 Uses the PHQ-9 questionnaire, which is a clinically validated tool. This isn't some random BuzzFeed quiz — it's the same screening doctors use. Other apps like Calm or Headspace don't include clinical assessments at all, while Sanvello does but buries it behind a paywall. This app gives you the real deal for free, no premium version hiding the useful stuff.
• 😊 No account creation required. You open the app and start answering questions immediately. Compare that to Happify or Woebot, which ask for your email before you can do anything useful. It respects your privacy from the start, which matters a lot when you're dealing with sensitive mental health data.
• 😊 Results come with a clear, color-coded severity indicator and a disclaimer that it's not a medical diagnosis. The app draws a line between "this is what the test suggests" and "go see a doctor," which is more responsible than apps like Youper that sometimes blur that line with their AI-driven suggestions.

• 🏆 Completely free with no paywalled features. Unlike Moodpath, which locks detailed tracking and journaling behind a subscription, this app gives you the full assessment tool without asking for a credit card. You can take the test as many times as you want without hitting a limit or seeing an upgrade prompt.
• 🏆 Minimalist design that reduces anxiety. Some mental health apps, like BetterHelp's companion app, have cluttered dashboards that ironically stress you out. This one uses a simple white background, large fonts, and one question at a time — no visual overload while you're already emotionally vulnerable.
• 🏆 Results are exportable as a PDF you can share with your doctor. This is surprisingly rare — apps like Wysa and Replika let you track moods but don't give you a printable clinical summary. Being able to hand your therapist a standardized PHQ-9 chart saves a lot of "well, I've been feeling..." awkwardness in appointments.

• ❌ No crisis resources or immediate help links. If your score comes back in the severe range, the app just says "consider seeking professional help" without offering hotlines or emergency contacts. Moodpath does this much better by directly suggesting local resources and crisis lines based on your location.
• ❌ No ongoing tracking or habit integration. This is a one-off questionnaire app — it doesn't track your mood daily, remind you to check in, or connect to your sleep or exercise data like Daylio does. If you want longitudinal trends, you're better off with a journaling app that graphs your moods over months.
• ❌ Lacks educational content or coping strategies. After completing the assessment, you just get your score and a doctor recommendation. Apps like Sanvello and Headspace offer guided meditations, CBT exercises, and articles that explain what your results actually mean in practical terms. This app assumes you already know what to do next.
