Activity Wheel — A Random Picker for What to Actually Do Right Now
Free afternoon, zero ideas? Type a handful of things you could do, spin, and let the wheel make the call. Cryptographically random, works offline, no signup.
The boredom buster for 'I don't know, what do you want to do?'
wheel.expertを選ぶ理由
End the 'I Don't Know, You Pick' Loop
Two people staring at each other, neither willing to choose — you know the standoff. Load five or six options, spin once, and the wheel breaks the deadlock so nobody has to be the bad guy.
Works on the Couch, the Car, the Cabin
Bad signal at the rental, no signal on the road trip? Doesn't matter. The wheel installs as a web app and spins with no connection at all — useful exactly when you're somewhere without much else to do.
Fill It With Your Own Ideas
The wheel only spins what you type. Drop in 'bake bread,' 'finally hang those photos,' 'walk the long way to the park' — real things you'd actually do, not generic filler from a list someone else wrote.
Rescue a Rainy Saturday With Kids
Build a wheel of screen-free options — fort, puzzle, baking, sidewalk chalk if the sky clears — and hand the choosing over to the spin. Kids argue with each other. They rarely argue with the wheel.
No Hidden Favorite
Some random pickers quietly lean toward the first item on the list. This one pulls from the Web Crypto API — the same randomness browsers use for security — so 'go for a run' and 'nap' land with exactly equal odds.
Free, No Account, Nothing Saved
Open it, spin it, do the thing, close the tab. There's no login wall, no email capture, and your list of plans never leaves your screen.
How to Use the Activity Wheel
Brain-Dump Your Options
Type whatever you could plausibly do with the next couple of hours. Start from the sample ideas if you're blanking, then swap them out — 'read on the porch,' 'reorganize the bookshelf,' 'call grandma.' Anything goes.
Tune the List
Cut the ones that don't fit today's weather, energy, or budget. A wheel of free indoor ideas reads very differently from a wheel of pricey day trips, so shape it around what's actually on the table.
Give It a Spin
Tap the middle. The wheel turns, slows, and stops on one activity — picked by the algorithm, not by whoever's hovering over the screen trying to nudge it.
Just Go Do It
Take the result at face value and start. Talked yourself out of it? Pull that option off and spin the rest. Earlier picks sit in the history panel if you want to circle back.
What People Actually Use the Activity Wheel For
Killing a Boring Afternoon
You've got hours free and somehow nothing feels appealing — classic decision fatigue. Listing the options and spinning short-circuits the overthinking and just gets you moving.
Rainy-Day Plans With the Kids
School's out, the rain isn't, and the whining has started. A wheel of screen-free ideas turns 'I'm bored' into a game where the spin assigns the next thing to build, draw, or bake.
Date Night Without the Menu Paralysis
Couples spin to pick the shape of the evening — mini-golf, a gallery, a long walk and dessert. For where to eat specifically, the food wheel does that one job better.
Self-Care and Wellness Prompts
Build a wheel of small resets — stretch, journal, step outside, ten quiet minutes with tea — and spin when you can't decide how to actually take a break.
Weekend and Family Planning
Saturday morning, everyone wants something different. Each person adds one idea, the wheel decides, and the negotiation ends before breakfast does.

真にランダムな選択 - アルゴリズムの仕組み
Math.random() を使用する多くのホイール スピナーとは異なり、wheel.expert は暗号的に安全な乱数を生成するためにWeb Crypto API (crypto.getRandomValues()) を使用します。これは、パスワード ジェネレーターなどのセキュリティ クリティカルなアプリケーションで使用されるものと同じ API です。
ウェブ暗号化 API (CSPRNG)
すべての最新ブラウザに組み込まれている暗号的に安全な擬似乱数ジェネレーター (CSPRNG)である crypto.getRandomValues() を使用します。
不偏選択アルゴリズム
すべてのエントリの重みが等しい場合は、 ランダム選択でよくある問題であるモジュロ バイアスを排除するために拒否サンプリング を使用します。これにより、 各エントリが選択される確率が数学的に等しいことが保証されます。重み付けされたエントリでは、確率は割り当てられた重みに比例します。
クライアント側の透明性
すべてのランダムな選択はスピンの瞬間にブラウザ内で行われます。コードはオープンであり、ブラウザーの DevTools 経由で検査できます。重要な景品の場合は、視聴者に対する公平性の証拠としてスピンを画面録画することをお勧めします。
🔍 自分で確認してください: DevTools (F12) を開き、コンソールで乱数の生成を確認します。私たちは window.crypto.getRandomValues() を使用します。これは銀行やセキュリティ アプリケーションで使用されているのと同じ暗号化 API です。

よくある質問
The activity wheel answers the broad question — 'what should we even do?' Once you've narrowed it down, the specialized wheels take over: the food wheel for where to eat, the movie picker for what to watch, the game picker for which game. Spin here first, then hand off.
Yes, and you should. Clear the samples and type the things you'd genuinely consider — 'repot the plants,' 'bike to the lake,' 'finally watch that documentary.' The wheel only spins what you load, so the result is always something realistic for your day.
It is. The picker draws from the Web Crypto API, the same source browsers use to generate security keys, so the first item on your list has no edge over the last. Nobody's thumb on the screen changes the odds either.
Build a wheel of screen-free, rainy-day activities — forts, baking, drawing, a scavenger hunt — and let each child spin. It reframes 'I'm bored' as a game, and a spin tends to settle a sibling standoff faster than a parent can.
It does. The activity wheel installs as a progressive web app, so after the first visit it runs fully offline — which is handy on a road trip, at a cabin, or anywhere the signal drops and you suddenly need something to do.
For a broad mix of options, yes. But if you specifically want to pick a workout or a physical sport, the sports wheel is built for that. Use this one for general 'what to do,' and reach for the specialized wheels when the decision gets narrow.
