TortoScope

Snap a plant. Find out if your tortoise can eat it.

A wildflower in the garden, a weed on a walk, a houseplant you're about to put in the enclosure. Take a photo and TortoScope tells you what it is, whether your tortoise can eat it, and why.

Free on iPhone, iPad and Android · 3 free identifications a day

How it works

From photo to answer in seconds

Photograph a leaf, a flower, a fruit or the whole plant. TortoScope identifies it with Pl@ntNet, then looks every likely match up in its own safety catalogue.

  1. Open IdentifyTake a photo with the camera, or pick one you took earlier from your library.
  2. Choose the plantHere, a yellow-flowered succulent spotted on the dunes.
  3. It's identifiedThe photo goes to Pl@ntNet, and each likely species is checked against the catalogue.
  4. See the verdictHottentot Fig, 96% likely: In Moderation. Every match shows its own rating and reference photos to compare.
  5. Read the plant's pageThe rating, the reasons for it, your own photos and where the plant grows wild.

Four ratings

A clear answer, with the reasons behind it

Every plant in the catalogue has one of four ratings, written from the cautious habits experienced keepers follow for a varied diet.

✓Safe

Fine to feed as a regular part of a varied diet.

e.g. Abutilon, Abyssinian Banana

!In Moderation

Good food, but not every day. Mix it in with other plants.

e.g. Dandelion, Hottentot Fig

–Sparingly

An occasional treat only, in small amounts.

e.g. Acer

✕Do Not Feed

Toxic or harmful. Keep it out of the enclosure.

e.g. Aconite

Every entry tells you

  • The rating, and how often (if ever) to offer it
  • Which parts are safe and which aren't
  • The compounds to watch, such as oxalates, saponins and cyanogenic glycosides
  • Reference photos, so you can check the identification yourself
  • Similar-looking plants you shouldn't confuse it with
  • Its family, other common names, and where it grows wild

Honest about doubt

It tells you when it isn't sure

Plant ID from a photo isn't perfect, so TortoScope shows how confident each match is and never guesses quietly.

A confident match

The species is clear, so you get its rating straight away, with reference photos to compare against your own.

A close relative

When a plant isn't in the catalogue but its relatives are, you see their rating, marked as likely. If even the species is uncertain, it shows the most likely genera and families.

Not in the catalogue

If there's nothing to go on, it says so rather than guess. The scan stays in your history, and if the plant gets a rating later, the app lets you know.

Where it grows

Every plant's page now has a map of the regions it's native to and where it's been introduced, from the Royal Botanic Gardens, Kew.

NativeIntroduced
  • Filter the plant list to the ones that grow wild where you live. Handy when you're out foraging.
  • Your region is guessed from your time zone, so no location access is needed.
  • If it's not quite right, choose your own in Settings, from the list or with your location. Your location is only used to find the region; it isn't stored or sent anywhere.

The catalogue

Over 1,200 plants, free to browse

Look anything up before it goes in the enclosure. Search by common or scientific name, or filter by rating.

  • Wildflowers, weeds and herbs common in UK and US gardens
  • Vegetables and salad greens you might already have at home
  • Houseplants, the safe ones and the toxic ones to avoid, such as Pothos, Philodendron and Dieffenbachia
  • Tropical plants for fruit-eating species like Redfoots and Yellowfoots
  • Grasses for grazers such as Sulcatas and Leopards
  • Cacti and succulents, including Opuntia

The catalogue keeps growing, and updates arrive in the app without a new version.

Why it matters

Getting the diet right

Captive tortoises rely on their keepers for nutritional balance. Wrong food choices contribute to metabolic bone disease (MBD), shell pyramiding, gout and digestive problems. Even safe plants can cause trouble at the wrong frequency: too much oxalate blocks calcium absorption, too much protein stresses the kidneys, and the wrong calcium-to-phosphorus ratio undermines shell growth.

TortoScope helps you feed a varied, safe diet without the guesswork. It's built for keepers of

  • Russian
  • Hermann's
  • Sulcata
  • Leopard
  • Marginated
  • Greek
  • Indian Star
  • Hingeback
  • Redfoot
  • Yellowfoot

and is useful for other plant-eating reptiles too, such as green iguanas.

About the safety information. The advice in TortoScope reflects established tortoise-keeper knowledge and the conservative principles experienced keepers apply to a varied diet. It's guidance: if you're unsure about a plant, your tortoise is unwell, or you keep an unfamiliar species, ask a reptile vet before feeding. The app supports good husbandry; it doesn't replace UVB lighting, calcium supplements, regular weight checks or any other part of proper care.
