株式会社秋月電気通商でのお買い物を楽しく、便利にするアプリ「Parts Cart」です。 事前のパーツリスト作成、および店頭での効率よいパーツ購入を目的として作成しました。 秋月電子でのお買い物で一番楽しいのは、所狭しと並べてあるパーツを心ゆくまで眺め、思いがけないパーツがあった場合にカゴに入れる楽しみがあると思います。 その一方、あらかじめ購入するパーツが決まっている場合、何らかの方法でメモを取り、お店で目的のパーツを探すことも多いと思います。 しかし、次のようなケースも多いのではないでしょうか。 ・ 欲しいパーツを購入金額を確かめるために、Microsoft Excel などの表計算ソフトを使い、毎回合計金額を計算している。 ・メモを作ったが、どのパーツまで集めたか記録していないため、帰宅してから買い忘れに気づいてしまった。 ・欲しいパーツの品番はわかっても、棚のどの場所にあるのかわからず混乱した。 ・目当てのパーツが棚になかったが、実は店員さんにお願いして倉庫から取り寄せてもらう必要があった。 などなど。 しかし、Parts Cart App を使うことによって、これらの問題が少しでも解決できるかもしれません。 === 機能 === ・パーツボックス   - 追加したパーツの確認   - 選択したストア(秋葉原店、八潮店)での在庫位置確認   - 不要になったパーツの削除(左スワイプ)   - 購入済みパーツのチェック(右スワイプ)   - 通販コードを利用したパーツの検索   - 秋月電子通商公式ページでのパーツ詳細確認   - 購入パーツ数の変更   - パーツボックスへのパーツの追加 ・検索履歴   - 過去に検索したパーツの履歴表示   - 履歴からパーツボックスへの登録 ・パーツボックス内パーツを秋月電子通商の通販ページへ一括登録 === 将来のバージョンで実装する機能 === ・複数パーツボックスの管理 ・人気パーツの検索(他のユーザとの共有)
