自己投資をして、 教材を買って、 やる気もある。 それなのに、 なぜか前に進めていない気がする。 それは、 やる気や能力の問題ではありません。 やることが増えすぎただけです。 Polarisは、 やることを増やすタスク管理アプリではありません。 理想から逆算して、 「今やらなくていいこと」を減らすためのアプリです。 Polarisでは、 ・理想の状態 ・そこへ向かうロードマップ ・今いるステップ ・今日やるべき一歩 を、ひとつの流れとして整理します。 その結果、 「今やっていることが、どの理想につながっているのか」 が自然と分かるようになります。 ■ 減らす 理想から逆算し、 「今日やるべき一歩」だけを表示。 やることが減ると、人は動けます。 ■ 支える 人は迷います。 Polarisは、 迷ったときに戻れる“現在地”を残します。 ■ 積み上げる この一歩に意味があると分かるから、 続けられる。 続くから、積み上がっていきます。 Polarisは、 一度で使いこなすためのアプリではありません。 迷ったら戻ってきて、 また「今日やる一歩」を確認できれば、それで十分です。 スマホに北極星を。 Polarisは、 迷ったときの“帰る場所”になります。 【Apple利用規約】 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 【Polaris利用規約】 https://www.polaris-app.jp/terms.html 【Polarisプライバシーポリシー】 https://www.polaris-app.jp/privacy.html
Decade

Ten years will pass either way. The only question is whether you'll have a tree. Decade turns what you put into money, health and reading into a tree that grows. Log once a day and it grows a little. Stop, and it doesn't die. One tree, five stages Seedling, sapling, growing, mature, ancient. Size isn't your streak. It's your accumulated years — each year's completion rate multiplied by how much of that year you were here, added up. Three areas, one tree Wealth. Set a monthly amount to put in. Log the transfer. Health. Set a weekly count or duration. Knowledge. Set books per year. Track reading with a timer. Run all three, or just one. A missed day doesn't reset anything Most habit apps score you on consecutive days. Miss one and you start over. This one doesn't. Finish sixty percent of the year and the tree grows sixty percent. That sixty percent stays. Health and knowledge allow two backfills a month. Wealth allows none — the transfer either happened or it didn't. The first thirty days are a calibration window. Adjust your targets freely; aiming too high costs you nothing. Blossom and fruit At ninety percent of your yearly target, the tree blossoms. At one hundred, it fruits, and the fruit stays until January first. At the end of each year, that year is recorded as a good year or a lean one, and drawn as a ring. Lean years get drawn too. They were part of it. About the rate of return Wealth projections use a rate you enter yourself. The screen always says "you assume X%", because that's what it is — an assumption, not a promise. This app recommends no investments and tells you nothing about what to buy. No account, no server No sign-up, no login. Open it and use it. Everything stays on your phone. Nothing is uploaded. You are not tracked. Decade Pro — one purchase, not a subscription Removes ads Twelve tree styles: sakura, maple, ginkgo, ink, gold leaf, glass, ember, coin and more iCloud backup and restore on a new device Bought once is bought. Tap Restore Purchases on a new phone. The free version works forever, with all three areas fully available.
