SteadGrow vs PictureThis
Honest comparison for Australian gardeners

At-a-glance comparison

The philosophy difference

PictureThis and SteadGrow approach plant care from opposite directions.

PictureThis is an identification engine that added care advice on top. Its strength is scale — more species recognised, more photos trained on, more markets served. Its weakness is that the care advice is generic: a tomato plant gets roughly the same watering recommendation whether you live in Darwin or Hobart, and regardless of this week's forecast. For a user whose main need is "what plant is this?", PictureThis is genuinely best-in-class.

SteadGrow started from the opposite end. It was built by an Australian gardener who was frustrated that plant apps told him to water tomatoes on a Tuesday when it had been raining all week. The identification engine is there, but the real focus is ongoing care that adjusts to your specific location and current weather. The trade-off is breadth: we launch with 159 plants, not 17,000, because we would rather have genuine care context than a shallow database.

Weather integration — the core difference

This is the single biggest functional gap between the two apps.

PictureThis recommends watering based on the plant's species and a generic seasonal model. If the app's logic says tomatoes need watering every three days, that is what you will see — whether it rained yesterday, whether a 40°C heatwave is forecast tomorrow, or whether your pot is in full sun or shade. The app has no awareness of your local conditions.

SteadGrow pulls live forecasts from the Bureau of Meteorology for your postcode. If 25mm of rain is forecast within 48 hours, SteadGrow tells you to skip watering. If the overnight minimum is 2°C, it flags frost risk before it hits. If a week of 38°C days is coming, it recommends moving pots and increasing mulch ahead of time, rather than reacting after damage.

For Australian conditions — which swing harder than most climates PictureThis was designed for — that difference shows up in real outcomes. How weather affects your garden covers the mechanics of why this matters.

Pricing — what "free" actually means

Both apps are free to download. The difference is what happens after that.

PictureThis runs a standard subscription model: you get a seven-day free trial, after which you are automatically charged the annual subscription fee (around US$29–40, depending on region and promotion). The card is collected upfront. Many users report the trial countdown is difficult to find in the app, and several App Store reviews describe charges appearing after users thought they had cancelled. The subscription covers unlimited identifications, disease diagnosis, and detailed care guides.

SteadGrow launches with a genuinely free tier: no credit card required to start, no trial that auto-rolls to paid, and one-tap cancellation for any paid features added later. Our Our Promise page documents this in writing. The free tier covers plant identification, weather-smart care schedules, and growth tracking.

This is the area where SteadGrow was intentionally built as the opposite of what the category normally does. If transparent pricing matters to you, this is decisive. If you do not mind paying for mature software, PictureThis's subscription buys you a legitimately larger feature set today.

Privacy and data handling

PictureThis is owned by Glority LLC (Glority Global Group Ltd), a company headquartered in Japan with operations worldwide. Its privacy policy permits sharing user data — including plant photos and location information — with third-party advertising networks and analytics providers.

SteadGrow is an Australian-owned business. We do not run third-party ad trackers, we do not sell user data, and plant identification runs locally on the device where possible. Your data stays yours. This is not a differentiator for every user, but for anyone who cares about where their photos end up, it matters.

Plant catalog depth vs breadth

PictureThis's catalog is much larger: the company claims 17,000+ species worldwide. If you need to identify an unusual houseplant, a tropical fruit tree, or a weed in a national park, PictureThis is more likely to have it.

SteadGrow's catalog is 159 plants at launch, curated for Australian gardens — common edibles, AU natives, popular ornamentals, weather-sensitive species. For each plant in the catalog, we provide climate-zone-specific planting calendars, BOM-aware care schedules, companion plant suggestions, and disease-prevention context. Coverage expands over time, prioritised by what Australian users actually grow.

The practical rule: if you mainly identify plants, PictureThis wins on catalog. If you mainly grow plants in Australia and want ongoing care context, SteadGrow wins on depth for the species that matter.

When PictureThis is the better choice

The honest version: plenty of Australian gardeners run both — PictureThis for occasional identifications when travelling or confronting an unfamiliar plant, SteadGrow for the day-to-day "what does this garden need this week" routine. They do not have to be mutually exclusive.

What SteadGrow does not do yet

Fairness requires saying where SteadGrow is not yet competitive.

• Catalog size. 159 plants vs 17,000. We will grow, but PictureThis has a decade head start.
• Identification of unusual or tropical species. Our AI is trained on a smaller set; PictureThis handles rare species better.
• Global coverage. We are Australia-only. If you live outside Australia, SteadGrow will not give you BOM-backed advice, and most of the climate-zone modelling does not apply.
• Length of track record. PictureThis has been in the market since 2017. SteadGrow is pre-launch at the time of writing. Maturity matters.

We will not pretend those gaps do not exist. What we will say is that the gaps we care most about closing — pricing honesty, local weather awareness, Australian climate modelling, privacy — are already closed on day one.

Common questions

Verdict

PictureThis is a mature, capable plant app with the largest catalog in the category. For global identification and broad species coverage, it remains best-in-class. If you are willing to pay a subscription and you do not need local weather awareness, it will serve you well.

SteadGrow is narrower and newer, but it is designed around the one thing PictureThis does not do: real integration with Australian conditions. If you garden in Australia and you want advice that actually responds to the weather and climate you live in, SteadGrow is the more appropriate tool — and the pricing transparency is a meaningful bonus.

Two apps, two legitimate answers. Choose based on what matters to your garden, not to a marketing page.
