PictureThis vs Plantin: Which Plant App Is Worth It? (2026)

PictureThis and Plantin are the two plant app names you’ll see most often when you start looking for help with your plants. Both are free to download on iOS and Android, both sell premium features through in-app purchases, and both carry high ratings on the US App Store: PictureThis sits at 4.8 from about 1.1 million ratings, and PlantIn at 4.6 from about 229,000. The catch is that their feature lists overlap a lot, so the right pick comes down to the details and how you’ll actually use the app.

If you’ve been going back and forth between the two, or you’re wondering whether to switch from one to the other, this breakdown covers what each app’s store listing says it does, how the pricing is listed, and which one fits which situation in 2026. Everything below about either app comes from its own App Store or Google Play listing or official website, checked in September 2026.

Quick answer: Both apps identify plants from a photo, diagnose sick plants from a photo, send care reminders, and let you ask human experts. PictureThis lists the larger species database (over 400,000 species) plus toxic-plant warnings and weed identification. PlantIn lists a watering calculator, weather alerts for outdoor plants, and a lifetime purchase option. If what you need most is a sick-plant diagnosis with organic, biological, and chemical treatment options side by side, PlantlyAI is built around that one job.

What PictureThis Does Best

PictureThis is made by Glority Global Group Ltd., according to its App Store listing. The listing says it can identify over 400,000 plant species from a photo, and the app is available in English plus 27 more languages. On Google Play it’s rated 4.5 from about 800,000 reviews and shows more than 50 million downloads.

Identification is only part of it. The listing describes plant disease diagnosis from a photo, with treatment advice and “a step-by-step treatment plan,” along with care tips covering watering schedules, fertilization times, and light conditions. There’s a water tracker that sends watering reminders, a light meter, toxic plant warnings for pets and kids, weed identification, and a plant collection with a wishlist. The listing also says you can chat with PictureThis’s experts 24/7.

On pricing, PictureThis is free to download. The US App Store lists in-app purchases for “PictureThis Pro” at $3.99, $7.99, and $39.99, and a “PictureThis Family Plan” at $49.99. The listing doesn’t say which price matches which billing period, so check the options inside the app before you buy. The App Store describes Pro as “Unlimited plant IDs, care tips, and diagnoses,” and says a free trial is offered.

Like any App Store subscription, it renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, as the listing notes. If you’re only testing it, set a calendar reminder.

What Plantin Does Best

Plantin’s App Store listing leans hard into plant care. It describes Personalized Care Plans with watering, fertilization, lighting, and even pruning instructions for “almost any species, from common houseplants to exotic cultivars.” Care Notifications remind you about watering and fertilization schedules, and weather notifications warn you about storms, freezing temperatures, and other conditions that could harm outdoor plants.

Two tools stand out in the listing. The Watering Calculator asks you several questions about your plant’s conditions and works out how much water it needs. The Light Meter uses your camera and AR to measure the light around a plant and tell you whether to move it somewhere brighter or shadier. Overwatering and underwatering are two of the most common reasons houseplants struggle, so a tool that adjusts per plant can help anyone with a mixed collection.

Plantin covers identification and diagnosis too. Its Google Play listing describes photo-based plant identification and an “AI-based plant disease identifier”: snap a sick plant or upload a picture, and the app diagnoses the problem and how to deal with it. There’s also a “Botanist Help” feature (called “Ask the Botanist” on the App Store) for consultations with the app’s gardening experts, plus a personal plant collection, a history journal, and a mushroom identifier. The App Store lists the developer as Vortemol Limited, and the Google Play page shows 10M+ downloads.

PictureThis vs Plantin: Direct Comparison

Here’s how the two apps compare across the features that matter most, based on their own listings:

Species identification: Both identify plants from a photo. PictureThis’s listing cites over 400,000 species. Plantin’s Google Play listing cites more than 24,000 species. If breadth of coverage matters most, PictureThis lists the bigger database.

Care reminders and scheduling: Both have them. PictureThis lists watering schedules, fertilization times, and a water tracker with reminders. Plantin lists personalized care plans, watering and fertilization reminders, a watering calculator, and weather alerts.

Disease detection: Both diagnose from a photo and give treatment guidance. PictureThis describes a step-by-step treatment plan. Plantin says it diagnoses the problem and how to deal with it, and its experts can prepare a custom DIY treatment plan.

Expert help: Both offer it. PictureThis lists 24/7 chat with its experts. Plantin lists consultations with its gardening experts.

Pricing: Both are free to download with in-app purchases. PictureThis lists purchases from $3.99 to $49.99 without naming the billing periods. Plantin’s App Store listing names its options, from $6.99 for “Weekly Premium Plant Care” to $49.99 for “Lifetime Premium Plant Care,” with “Premium Access Yearly” at $29.99. Because PictureThis doesn’t label its periods, there’s no clean like-for-like comparison (US App Store, checked September 2026; prices vary by region).

Free tier: Neither listing spells out exactly what’s included for free. Both show a free trial on the App Store without stating its length.

Getting started: Both start from a photo. Plantin’s Watering Calculator works from a few questions about each plant’s conditions, so expect a short setup per plant if you want its tailored watering advice.

Platform: Both are on iOS and Android.

Which App Should You Choose?

The answer depends almost entirely on why you need a plant app.

Choose PictureThis if identification breadth is the priority. You’re at a garden center, on a trail, or looking at an unfamiliar plant in someone’s home, and you want the app with the larger listed species database. Its toxic-plant warnings and weed identification are useful extras if you have pets, kids, or a garden bed to manage, and the Family Plan covers more than one person.

Choose Plantin if your focus is keeping a collection on schedule. The watering calculator, AR light meter, and weather alerts for outdoor plants are the tools its listing highlights, and it lists a lifetime purchase if you’d rather not keep a subscription running.

When Diagnosis Is the Real Priority

If the reason you’re looking at plant apps is that something is wrong with your plant right now, you want a clear next step: what to do, in what order, with what kind of product, and what to watch for afterward.

PlantlyAI is built around that specific job. Take a photo of the sick plant, and the app identifies the disease, pest, or problem. Then it walks you through a step-by-step treatment plan with organic, biological, and chemical options laid out side by side so you can pick what works for your situation. It covers houseplants, garden vegetables, flowers, trees, and crops, and there’s a searchable plant disease library if you want to read up on symptoms. Two diagnoses a day are free, with no account required.

If your plant has brown spots, mushy stems, yellowing leaves, or signs of a pest and you need to know exactly what to do, PlantlyAI is built around that diagnose-and-treat workflow.
