About

Solspot

Features
Read full description

Solspot measures how much light a spot in your home actually gets — then tells you which plants will live there. Lay your phone flat where the plant will sit, screen toward the light. Solspot reads your camera's light meter and gives you an honest answer: a category, a number, and the real range around it. MEASURE THE SPOT, NEVER THE PLANT Light is a property of a place, not a leaf. Solspot measures the light arriving where a plant would sit, the same way a leaf receives it. AN HONEST ANSWER, NOT FAKE PRECISION Every reading comes with the range it could really be. When your device hasn't been calibrated, the range widens and Solspot says so. If a spot is brighter than the camera can measure, Solspot tells you that instead of inventing a number. PLANTS THAT WILL ACTUALLY LIVE THERE Matched against your measured light — with the caveats included. A plant that will survive but sulk is shown as exactly that, not hidden behind a percentage. CARE THAT STARTS FROM THE LIGHT Add the plants you own and Solspot works out how often to check each one — from the light it measured where the plant stands, the pot it is in and the season, not from a calendar. It asks you to check the soil rather than telling you to water, learns from what you find, and sends one reminder a day that names every plant due. Your care history and notes stay on your phone, and you can export all of it. SEE IT IN YOUR ROOM Stand a plant on your own floor at the size its species actually reaches. Ten of the 100 species have a 3D model. Mature size is published as a range rather than a single number, so the size control spans that whole range and tells you which end you are looking at — and trailing species show trail length, not height. PET SAFETY, SOURCED NOT GUESSED Pet toxicity comes from the ASPCA's lists and nowhere else. When ASPCA doesn't list a species, Solspot says "unverified" rather than guessing. "We don't know" is never presented as "safe". SAVED SPOTS AND SEASONAL RE-CHECKS Save a windowsill and watch its light change through the year. Light in January is not light in July, and Solspot reminds you to re-check. FULLY OFFLINE No account and no server. Your plants, spots and photos stay on your phone. While measuring, the camera is a light sensor and no image is captured at all. In "See it in your room" it is a viewfinder, and the only picture that exists is one you take yourself — saved to your own Photos, and going nowhere else unless you share it. FREE — NO SUBSCRIPTION, NO ADS, NO IN-APP PURCHASES Every light reading including direct sunlight, the category and its honest range, plant matches with their caveats, every filter, buy links, unlimited saved spots, and care for every plant you own. All of it, free. The competitors that paywall sunlight are the reason this app exists.
