10 Best Free Plant Identification Apps For iOS & Android (2023)

Plant identification apps are handy tools for gardeners, explorers, and plant enthusiasts.

As a gardener or person who loves plants, you will face many cases when you need to determine the species of a particular herb, weed, houseplant, tree, or wildflower.

If the only method to identify unknown plants a few years ago was to ask an expert in the scientific study of plants or browse entire plant-related books, nowadays, this task has become considerably easier thanks to mobile apps.

There are numerous phone apps that can help you quickly and effortlessly identify many plant species by simply taking a photo of their leaves, flowers, fruits, or even bark when you need to determine the species of an unknown tree.

Most of us always have our mobile phones at our disposal and these apps can be priceless when you need to quickly identify a plant.

To make it easier for you to choose the apps that best suit your needs and preferences, we have created a list of some of the most popular apps with plant identification functions available for both Android and iOS.

Some of these are completely free, while others are powered by ads, or have a free version that only gives you access to a part of the features.

It should be mentioned that these apps were picked and listed according to our preferences. That doesn’t mean there aren’t other good apps out there still waiting to be discovered.

Note: The information in this article regarding the features/trial periods/prices/plans/database sizes of the apps presented may not be entirely accurate and can change at any time as the apps are frequently updated. You should always check the info presented in each app before deciding to purchase a paid subscription.

Free Apps

1. Pl@ntNet

Pl@ntNet is one of the most popular plant identification apps for mobile phones. According to the information displayed on the app’s official website, it was released more than ten years ago, so it is also one of the oldest in this field.

This app is labeled as “a citizen science project available as an app” as it is more of a community of plant enthusiasts and experts contributing to the app’s progress.

Pl@ntNet is free to download and use, and at this time, it doesn’t contain in-app advertisements or paid plans. It is a donation-based project and anyone is welcome to contribute and help the founders cover the costs of the development and servers.

This app has pretty good image recognition capabilities and can identify a plant from a photo of its leaves, flowers, fruits, bark, habit, or another part.

It has both a version for phones with the Android operating system and one for iOS, but also a web version that allows you to identify plants directly from the web browser by uploading an image, without the need to install the application on your device.

The database of this app is growing continuously thanks to the contributions of people all around the world.

Although you can register a user account to save your observations and share them with the community, you are not required to do so, and you can completely skip this step after opening the app.

2. Seek by iNaturalist

Seek is more than a mobile app for identifying plants. This app from iNaturalist utilizes the power of image recognition technology to help you identify unknown plants, fungi, and animal species from photos.

It is an outstanding mobile app for adventurers who like to spend their time exploring nature and want to learn more about the organisms around them.

The app is free to use, does not require you to register an account, doesn’t display annoying ads, and has a straightforward and clean interface.

You can also earn different badges for making observations and you can participate in various challenges.

3. iNaturalist

iNaturalist started as the Master’s final project of several students at UC Berkeley’s School of Information in 2008. Later, it became an initiative of the California Academy of Sciences and a joint initiative with the National Geographic Society.

The central goal of the iNaturalist app is to create a community of like-minded people. A place where wildlife experts, scientists, and regular people can share their findings (observations) and help the better understanding and preservation of the flora, fauna, and the environment in various world regions.

iNaturalist is more than an app designed to help you identify plants, but can also be utilized for that purpose.

If you don’t need the extra features, you can take a look at the simplified app originated from iNaturalist, which is called Seek.

To find out the name of a plant with iNaturalist, you have to go to “New Observation” from the app’s menu.

Next, select whether you want to take a photo or choose an existing image from the image gallery of your device.

Once you pick the desired photo, you have to click on the question mark before “What did you see?” for the app to compare the unknown plant with the ones in the app’s database and generate a set of possible matches.

4. Google Lens

Google Lens is a mobile phone app developed by Google and very popular among users with devices operating on Android OS as it may come already pre-installed. However, there is also available for iPhone users (iOS) and you can download it for free from Apple App Store.

This app has multiple handy features when it comes to photos, but what interests us more is the plant recognition function.

Google Lens uses the power of Google Images to enable you to identify objects, plants, text, and more, from a photo.

Quick Preview

While some other plant recognition apps included in our list might have a large library of plants available, I think they still cannot compete with the huge database of Google images.

Basically, with Google Lens, you can search and identify anything you see, regardless if it’s an animal, an object, or a plant.

If you are someone like me who only uses plant identification apps to only to find out the name of specific flowers, trees, or weeds, Google Lens is all you need.

This app is entirely free and incredibly powerful. However, since it’s not an app solely designed for identifying plants, do not expect it to give you too many details about those plants upfront. Thus, you might have to click the results to find out the plant name or more details about it.

The web alternative to Google Lens is Google Image Search.

So, if you need to find out the name of a particular plant when using your computer, you can use the “search by image” feature of Google Images (click the camera icon in the search bar of Google Images and select the image from your computer).

Then just browse through the results and find the plant that looks like the one in your picture.

Final Word

Regardless if you are a gardener, biologist, student, professor, wildlife explorer, or just someone who loves plants, a mobile app that helps you quickly identify plants from a photo is an invaluable instrument.

While there are numerous mobile apps available for devices operating on Android and iOS, not all of them are satisfactory, that’s why we have created this list.

We have only included apps that:

• Can identify a plant from a photo (either taking a new photo or uploading an existing one)
• Can be downloaded from Google Play Store or Apple’s App Store
• Are free or have at least a free version, free trial, or a way to get free credits
• Can recognize a wide variety of plants

Keep in mind that although a particular plant might be in an app’s database, sometimes, the software might still be having issues recognizing the plant due to factors like:

• Low photo quality
• Bad shooting angle
• Crowded backgrounds
• Inadequate plant part
• Low light

To improve the chances for these apps to identify a plant correctly, you should always take multiple photos from several angles and shots of various parts of the plant you want to identify (leaves, flowers, bark, etc.).

Also, some of these apps may have more accurate results when trying to identify the common houseplants while others may do a better job in recognizing the wild plants. You just have to find the one that works best for you.

We hope you’ll find our selection above useful and help you on deciding which app best matches your needs.
