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。
