Most plant apps look up a species and set a reminder. Botanical Legacy keeps a Digital Shadow per Specimen: a model of one plant, rebuilt nightly from its photos, care log, weather and sensors. It drifts from the species when yours does, and stays drifted: after a few weeks the model believes your plant over the reference. When the watering date moves, you can open it and see what moved it. Free for 5, no card. Full export on every plan.
