Solspot

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. 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, no backend, nothing uploaded. 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, and unlimited saved spots. All of it, free. The competitors that paywall sunlight are the reason this app exists.

その置き場所、植物にとって本当に明るいですか? 人の目は明るさに対して対数的に順応するため、300lxの部屋も3,000lxの部屋も同じ「明るい部屋」に見えてしまいます。「照度計アプリ」を入れてみたものの、数字の意味が分からず消してしまった——光量ノートは、そんな人のために作りました。 ■ 置くだけ3秒。無料で使えます iPhoneを置き場所に画面を上にして置くだけで、3秒ほどでその場所の明るさ(lx)が表示されます。数値だけでなく、「暗所/室内/明るい室内/明るい日陰/曇天屋外/直射日光」の明るさクラスと、モンステラ・ポトス・サンスベリア・アガベなど植物ごとの「不足/適正/過剰」の判定まで、すべて無料です。デスクワークや読書、手芸など植物以外の明るさ確認にも使えます。 ■ あなたの棚に合わせる ・用途チップをスライドするだけで、置いてある植物や作業に合わせて目標の明るさ帯が切り替わります ・光源プリセット(太陽光/白色LED/赤青育成LED/蛍光灯)で目標値を補正。赤青の育成LEDはlxの値が実際の光量より低く出るため、補正なしでは判定がずれてしまいます ・拡散板モード(紙やティッシュを1枚かざすだけ)で、より安定した測定に ■ Pro(¥800・買い切り、サブスクではありません) 無料版が「合否」を教えるのに対し、Proは「次の一手」を教えてくれます。 ・処方カード: 不足時に「ライトを約◯cm近づける」「窓から◯mへ」を逆二乗則で提案。急な移動で株を傷めないための順化ガイドと、暗い場所での水やり過多への注意も付きます ・積算ロギング: 画面をつけたまま一定時間の明るさを記録し、lux·hの積算値を算出。朝・昼・夕の3点入力から1日の積算光量とDLIの目安も推定できます ・地点の保存・比較: 窓際と棚下段など、複数の場所を名前を付けて無制限に保存し、2地点を比較 ・PPFD換算(目安): 光源プリセットごとの係数でPPFDのおおよその値を表示(赤青LEDは換算不可を正直に表示します) ・較正の保存: 分かっている明るさの場所を基準に、測定値を1点補正して保存 ■ 精度についての正直なお知らせ 光量ノートは、iPhoneカメラの露出情報から明るさを推定する「目安」のアプリです。業務用の照度計や測定機器の代替にはなりません。あくまで「置き場所同士の相対比較」「大まかな傾向の把握」のための道具としてお使いください。 ■ プライバシー カメラ映像は明るさの計算にのみ使い、保存も送信も一切行いません。アカウント登録・通信不要、完全オフラインで動作します。 こんな方におすすめです ・観葉植物、多肉植物、アガベ、塊根植物、ビカクシダなどを室内で育てている方 ・育成ライトの高さや窓際の置き場所に迷っている方 ・「この子、日照不足かも」と感じたことがある方
