Houseplant SOS: Pest ID

Something's wrong with your plant. Snapping a photo is the easy part. Actually curing it is not, and most apps stop at the photo.

Houseplant SOS is built around the part every other plant app skips: the three weeks after the diagnosis.

WHAT IT DOES

Take a photo. Get a ranked differential, not a single guess dressed up as certainty. If it's most likely spider mites, we say so, and we tell you what else it could be, plus a 30-second leaf test you can run yourself to confirm it.

From there you get a dated treatment calendar, timed to that specific pest's real biology. Spider mites need a different rhythm of applications than fungus gnats or thrips, and the calendar reflects that.

As you re-photograph the plant, the app scores an objective cured or not-cured trend from the images, not from how you feel about it. You'll know the treatment worked because the app says so, backed by the photos, not because the leaves looked a bit better one afternoon.

THE PART OTHER APPS SKIP

Other apps hand you a verdict and vanish. Houseplant SOS runs the treatment until it's cured: reminders on schedule, a trend that proves it's working (or that it isn't, so you can adjust), a quarantine register naming which nearby plants to check before the same pest spreads to them, and relapse history if it comes back.

HONEST BY DESIGN

When a photo isn't clear enough for a confident call, Houseplant SOS says so and walks you through a quick physical test instead of guessing anyway. You'll never get a single confident-sounding verdict that flips the moment you take another photo of the same leaf.

FREE, HONESTLY

Your first case runs completely free, start to cured: the diagnosis, the differential, the full treatment calendar, and the trend verdict. No trial countdown, no auto-converting subscription, no locked diagnosis behind a paywall. A second concurrent case, your relapse history, and the multi-plant quarantine map unlock with a subscription, billed monthly or annually, cancel any time in Settings.

Treatment guidance covers pest and disease classes only (horticultural oil, insecticidal soap, biological drenches, sticky traps, physical removal, isolation) and always points you to your chosen product's own label instructions. Houseplant SOS does not recommend or sell specific pesticide brands or dosing.

Catch spider mites, fungus gnats, and thrips before they spread. Get a ranked diagnosis you can confirm yourself. Follow a treatment calendar built around the pest, not a guess. See which nearby plants to check, and when. And this time, get proof it's actually cured.

Houseplant SOS Pro is available as a monthly or annual auto-renewing subscription. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.
