5 Best NatureID Alternatives in 2026

If you’re searching for NatureID, the first thing to know is that the app has a new name. Its App Store release notes for version 6.0 put it plainly: “NatureID got a new name—Plantum!” So if NatureID is already on your phone, you’re using Plantum today.

People still look at other plant apps for all sorts of reasons. Some want an app that costs nothing at all. Some want to identify birds and bugs as well as plants. Some have a sick plant and want a tool built around diagnosis and treatment. Each app below is described on its own terms, so you can match it to what you need.

NatureID alternatives worth considering include PlantlyAI for disease diagnosis and treatment, PictureThis for broad plant identification, PlantIn for care plans and reminders, Seek by iNaturalist for free identification of plants and animals, and Pl@ntNet for free, citizen-science plant ID. All five are free to download, and two of them are completely free.

NatureID Is Now Plantum

Plantum is published by AIBY and is listed on both the App Store and Google Play. Its App Store listing describes an identifier for 40,000+ natural objects, a Diagnose feature that returns a diagnosis with a list of treatment options, and watering, misting, feeding, and rotating schedules. It also lists a Light Meter, Pot Meter, Water Calculator, Weather Tracker, and a My Plants collection.

Plantum is free to download, and Plantum Premium is billed weekly, monthly, or annually. Check the store listing for current prices in your region.

You’ll also see other apps on the stores with “Nature ID” in their names. Those are listed by different developers and aren’t the original NatureID.

If Plantum already covers what you need, you may not need another app at all. If you want a different focus, the five apps below each do something a little differently.

Here’s the short version. PictureThis says it can identify over 400,000 plant species and has 4.8 stars from 1.1 million ratings on the App Store. Seek by iNaturalist draws on millions of observations submitted to iNaturalist and needs no account. Pl@ntNet is a free citizen-science project run by French research institutes. PlantIn bundles care plans, reminders, and diagnosis. PlantlyAI offers 2 free diagnoses per day with organic, biological, and chemical treatment options for each diagnosed problem, covering houseplants, vegetables, garden flowers, and crops.

The 5 Best NatureID Alternatives in 2026

Each app below solves a slightly different problem. Read the section that matches your situation before deciding. Prices are from the US App Store, checked September 2026; prices vary by region.

1. PlantlyAI: Best for Diagnosing Sick Plants

PlantlyAI is built around one core problem: you can see your plant is struggling, but you don’t know what’s wrong or how to fix it. Snap a photo and the app identifies the disease, pest, or care issue, then walks you through treatment options including organic, biological, and chemical remedies.

It’s not just “here’s what plant this is.” You get a diagnosis plus a step-by-step fix. If your monstera has brown spots from root rot versus sunburn versus spider mites, PlantlyAI gives you different treatment paths for each one.

The app covers houseplants, garden flowers, vegetables, trees, and crops. It works on both iOS and Android. The free tier gives you 2 diagnoses per day without requiring an account, which covers occasional spot-checking. If you’re dealing with an active outbreak across multiple plants, the premium subscription makes more sense.

What it does well: Specific disease diagnosis with tailored treatments, not just generic care tips. Free tier: 2 scans per day, no account needed. Platforms: iOS and Android.

2. PictureThis: Best for Pure Plant Identification

PictureThis says it can identify over 400,000 plant species, and it’s one of the most-rated plant apps on the App Store, with 4.8 stars from 1.1 million ratings. If you want to know exactly what plant is growing in your yard, what variety of rose you inherited from the previous owner, or whether that seedling is a weed, it’s built for that.

Its listing goes well beyond ID too: diagnosis with a step-by-step treatment plan, care tips and watering reminders, toxic-plant warnings, weed identification, a light meter, and a 24/7 chat with its experts. Think of PictureThis as a broad all-rounder, and PlantlyAI as a tool built specifically around the question “what’s wrong with my plant?”

What it does well: A very large plant species database plus care and diagnosis tools in one app. Free tier: Free to download; PictureThis Pro unlocks unlimited plant IDs, care tips, and diagnoses. Pricing: In-app purchases listed from $3.99 to $49.99. Subscriptions auto-renew unless turned off at least 24 hours before the current period ends. Platforms: iOS and Android.

3. PlantIn: Best for Plant Care Routines

PlantIn combines plant identification with ongoing care. Its listing covers disease diagnosis, personalized care plans, a watering calculator, an AR light meter, care and weather notifications, and “Ask the Botanist” consultations with the app’s gardening experts.

Where PlantIn fits best is as a plant-care companion for houseplant collectors who want reminders and routine management alongside identification.

What it does well: Bundled plant care: ID, care plans, watering help, and notifications in one place. Free tier: Free to download; Premium unlocks full access. Pricing: Premium in-app purchases listed from $6.99 (weekly) to $49.99 (lifetime). Platforms: iOS and Android.

4. Seek by iNaturalist: Best Completely Free Option

Seek is free, with no in-app purchases and no registration required. It’s made by iNaturalist, a not-for-profit organization, and its image recognition is based on observations submitted to iNaturalist and identified by the iNaturalist community.

Point the Seek Camera at a plant, bird, insect, or mushroom and it works its way down the tree of life toward a species. You earn badges for observing different types of species and joining challenges, which makes it a good pick for families.

If you want to identify birds, bugs, and fungi as well as plants, at no cost, Seek is the one to try.

What it does well: Real-time identification of plants, animals, and fungi, completely free. Free tier: Completely free, no subscription, no account needed. Platforms: iOS and Android.

5. Pl@ntNet: Best Free Option for Plant ID and Citizen Science

Pl@ntNet is a free citizen-science app. Its trademark is owned by four French research institutes: CIRAD, INRAE, INRIA, and IRD. Photograph a plant’s flowers, fruits, or leaves and it matches your photo against tens of thousands of species. The plants you photograph are collected and analyzed by scientists studying plant biodiversity, so every scan contributes to research.

In 2026 Pl@ntNet added a Diseases & Pests feature that identifies 395 diseases and types of pest damage across just over 100 plant species, with key crops in France covered first.

What it does well: Free plant identification, with a focus on wild plants, backed by research institutes. Free tier: Completely free, no in-app purchases. Platforms: iOS, Android, and web (identify.plantnet.org).

How to Pick the Right NatureID Alternative

The right choice comes down to what you actually need day-to-day.

If a plant is currently sick and you need to diagnose and treat it, PlantlyAI is the most focused tool for that job. The 2 free scans per day cover casual use.

If you identify plants constantly (dozens a week, rare varieties, unfamiliar species at the nursery), PictureThis has the largest species count on this list at 400,000+.

If you want reminders, care plans, and a watering calculator alongside identification, PlantIn bundles all of that together.

If you don’t want to pay anything, Seek and Pl@ntNet are both completely free. Seek covers plants, animals, and fungi. Pl@ntNet focuses on plants.

If you’re happy with NatureID as it is, remember it’s Plantum now, and its listing already includes identification, care schedules, and diagnosis.
