Fieldmark's listing describes confidence bands, genus-level fallback and guided questions for plant and fungi identification. It says the app does not certify edibility and highlights dangerous lookalikes.
iNaturalist describes Seek as a nature observation app that uses image recognition to explore plants and animals, with challenges and badges for learning about biodiversity.
Choose Fieldmark if its question-led plant and fungi workflow appeals to you, or Seek for broader nature exploration. Keep the observation evidence regardless of the app and never treat a recognized label as food-safety advice.
