Where PictureThis is stronger
- Identification at scale. If you want to know what that plant on a walk is, or whether something in the garden is a weed, PictureThis is built for it.
- Safety information. A toxic plant warning for pets and children is useful, and PotPal does not offer it.
- Reach. Twenty-eight languages and more than a million ratings show a very large user base.
When to choose PictureThis
- You collect plants and want to identify unknown ones quickly.
- A plant looks sick and you want diagnosis suggestions.
- You need toxicity information for pets or children.
When to choose PotPal
- You already know your plants and only need to know when to water.
- You want the interval explained, and a reminder that waits when you tell it the soil is still wet.
- You want no account and no feature overload.
- You want an app that says plainly it does not diagnose.
Moving from PictureThis to PotPal
There is no import between the two. Add your houseplants to PotPal one at a time from a photo or the common-plant list, and say when you last watered.
You can keep PictureThis for identifying new plants and use PotPal for the watering rhythm of the ones you own.
