PDR測位
Read full descriptionHide full description
PDRとは、「Pedestrian Dead Reckoning」の略で歩行者自律航法という手法です。 搭載されている加速度センサーやジャイロセンサーを用いて、 実際の動きから歩行を検知して、ユーザーの位置を推定することが可能です。 このアプリは、搭載されている各種センサーの情報からPDRによる位置推定を行って、 測位を開始した地点からの相対位置を示すアプリです。 ※ このアプリで、実際のユーザーの絶対位置は表示されません。 ◆ PDRによる測位 端末の加速度センサーとジャイロセンサーから独自のアルゴリズムを用いて、 測定開始後に歩行で移動したユーザーの相対位置を推定します。 歩行したユーザーの軌跡をリアルタイムに表示します。 現在位置座標については、テキストで表示します。 ◆ ユーザー情報の設定 歩行を検出するためのパラメータを、シンプルに設定します。 ----------- お問い合わせ先： 株式会社ムセンコネクト https://www.musen-connect.co.jp/

Verdict
The clearest difference is ads: PDR測位 at none against Watch Sensor Logger's shown. PDR測位 also leads on update cadence (every 12 months vs every 25 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
