Planta is a genuinely good app. Its care-scheduling interface is one of the most polished in the category, and its light-meter and step-by-step task view have earned it more than 6 million users. So why do so many people search for an alternative? Almost always one reason: price. In 2026 the features most people actually want — plant identification, disease diagnosis, personalized schedules and unlimited plants — sit behind Planta Premium, which runs about $7.99/month or $35.99/year (a three-month tier sits in between at $17.99). The free tier is limited mostly to watering reminders.
Below is an honest comparison. We build and ship one of these apps (Growli), so we have skin in the game — but the goal here is to help you pick the right tool, and we'll tell you plainly where each competitor wins.

The 5 best alternatives to Planta
1. Growli — best free all-rounder
Growli is an AI gardening assistant that combines the three things people usually cobble together from separate apps: photo identification, leaf-based problem diagnosis, and a genuine back-and-forth chat about your specific plant. Snap a photo, get a species match, then ask follow-up questions in plain English — "why are the lower leaves yellow?" — and get a reasoned answer rather than a generic care card. It also sends care reminders, frost alerts, and a daily plan.
Two things set it apart from Planta. First, it's free on iOS and Android — no paywall on identification or diagnosis. Second, it carries ASPCA-cited pet-safety data across a roughly 11,700-species care library, so you can check whether a plant is toxic to cats or dogs before you buy it. It's also UK-localized to RHS guidance, which most US-built apps aren't. It holds a 4.6 App Store rating with 7,000+ growers.
Pros: free; conversational AI; symptom diagnosis; strong pet-safety data; UK/RHS localization. Cons: newer and smaller community than Planta or Greg; less of a curated "collection showcase" interface.

2. Greg — best for a free community
Greg has built the strongest social layer of any plant app: an active in-app feed where growers post problems and get crowd-sourced advice. Its core care tracking and unlimited plant collection are free, which makes it the most obvious like-for-like swap if Planta's subscription is your only complaint.
Pros: genuinely generous free tier; the best community; clean watering schedules. Cons: advice quality varies (it's crowd-sourced, not expert-reviewed); diagnosis is less structured than a dedicated AI tool.
3. PictureThis — best for identification only
If your main use is pointing your phone at an unknown plant and getting a fast, confident species name, PictureThis is the market leader by catalogue size. It also offers care tips and disease info, but identification is where it shines.
Pros: huge species database; very fast, accurate ID; polished onboarding. Cons: a subscription of roughly $39.99/year — actually pricier than Planta — with a trial that auto-converts; ongoing care features are thinner than Planta's. See our best plant identifier app comparison for the full ID-app field.
4. Plantum — best for expert backup
Plantum (formerly NatureID) identifies 33,000+ species, diagnoses plant health issues, and — unusually — offers online consultations with professional botanists on its paid plan. At about $29.99/year it's a touch cheaper than Planta.
Pros: large ID database; disease diagnosis; access to human botanists; weather-aware care. Cons: the best features are paywalled; the botanist feature is the main reason to choose it over cheaper rivals.
5. Blossom — best for a simpler, prettier reminder app
Blossom identifies 30,000+ plants and leans on behavioral-design polish to nudge you into consistent watering. It includes a light meter, a water calculator that factors in pot size, and disease identification.
Pros: clean, approachable design; helpful watering calculator; solid ID. Cons: paid subscription for full features; less depth than Planta on long-term care scheduling.
How to choose
Be honest about your bottleneck. If your plants keep dying and you don't know why, prioritize diagnosis and conversational help — that's Growli's wedge. If you love scrolling a feed of other people's plants, Greg's community is unmatched. If you mostly need to name mystery plants on walks, an ID specialist like PictureThis or Plantum is the tighter fit. And if you genuinely love Planta's interface and the price doesn't bother you, there's no shame in staying — it's a good app.
The one thing worth stressing: identification is now a commodity across all of these apps. In 2026 the real differentiator is what happens after the species name comes back — whether the app can reason about your specific plant, warn you if it's toxic to your pet, and adjust to your actual growing conditions.

Frequently asked questions
Is there a free alternative to Planta?
Yes. Growli is free on iOS and Android with no paywall on plant identification or diagnosis, and it adds conversational AI care, care reminders and ASPCA-cited pet-safety data. Greg also offers a generous free tier built around a community feed. Both are strong swaps if Planta's subscription is your main reason for leaving.
Why is Planta so expensive?
Planta puts most of its useful features — plant identification, disease diagnosis, personalized care schedules and unlimited plants — behind Planta Premium, which runs about $7.99 per month or $35.99 per year. The free tier is mostly watering reminders, so getting real value effectively requires the subscription, which is why many people look for a cheaper or free alternative.
Is Planta worth it?
Planta is worth it if you value a polished, beautifully organized care-scheduling interface and don't mind paying around $35.99 a year. Its light meter and per-plant task view are excellent. If you'd rather not pay, or you want conversational diagnosis and pet-safety data, a free app like Growli or Greg covers most of the same ground at no cost.
What is the best free plant care app?
For a free all-rounder, Growli combines photo identification, leaf-based problem diagnosis, conversational chat, care reminders and pet-safety data at no cost. Greg is the best free option if you specifically want a social community feed. Most other apps, including Planta, PictureThis, Plantum and Blossom, gate their strongest features behind a paid subscription.
Can I identify plants without paying like I do in Planta?
Yes. Growli includes plant identification for free, so you don't need a subscription just to name a plant. If identification is your only goal, PictureThis and Plantum have very large species databases, but both charge an annual subscription — around $39.99 and $29.99 per year respectively — so they aren't cheaper than Planta.
Which plant app is best for pet owners?
Growli is the strongest choice for pet owners because it carries ASPCA-cited toxicity data across roughly 11,700 species, so you can check whether a plant is toxic to cats or dogs before buying it. You can browse the same data on our pet-safe plant hub. Most other apps mention toxicity only in passing rather than as structured, sourced data.
