3ステップで速度を測る

01
「スタート」を押す

ブラウザが位置情報の許可を求めます。「許可」を押すとGPSで速度を読み取れます。

02
移動を始める

速度は毎秒更新されます。ダッシュボードや窓際など、空が見える場所にスマホを置いてください。

03
最高速度と距離を確認

現在の速度のほか、最高速度・平均速度・距離も表示。mphやノットにいつでも切り替えられます。

こんなときに便利

車・バイク

メーターが壊れているときや、表示が高めに感じるときに実際の速度を確認。

電車・バス

窓際に座って、電車の速度と移動中の最高速度をチェック。

自転車・ランニング

毎回の速度、ペース、距離を記録。

メーターの確認

車のメーターはほとんどが実速度より少し高めに表示されます。GPSと比べてみましょう。

よくある質問

今の速度はどうやって確認しますか?

「スタート」を押して位置情報を許可してください。数秒で速度がkm/hで表示され、毎秒更新されます。アプリや登録は不要です。

正確ですか?

空が開けた場所なら、スマホのGPSの誤差はたいてい1〜2km/h以内です。トンネルや高いビルの間では電波が弱く、一時的に数値がぶれることがあります。

ネットなしでも使えますか?

使えます。GPSは衛星を使うのでインターネットは不要です。ページを開いた後はオフラインでも測定できます。

なぜ0と表示されますか?

止まっているときや、GPSがまだ位置をつかめていないときは0になります。動いているのに0のままなら、開けた場所に移動し、位置情報がオンで許可されているか確認してください。

無料ですか?

はい、完全無料です。登録もアプリも不要で、すべてブラウザで動きます。
