LockTagは、衝動買いやアプリの使いすぎを「物理的に」抑えるセルフコントロールアプリです。 ■ 特長 ・制限したいアプリ(買い物・SNS・動画・ゲームなど)をスクリーンタイムでロック ・解除は、現実のNFCタグをかざした時だけ。冷蔵庫や玄関など「ちょっと不便な場所」に貼れば、衝動にブレーキ ・承認者(家族・恋人・友人)の許可で解除する使い方も選べます ・家族グループの誰か1人が承認すればOK、という設定も可能 ■ こんな人に ・ネットショッピングやSNSをつい開きすぎてしまう ・自分の意志だけでは止めにくい ・誰かに見守ってもらいながら習慣を変えたい ■ プライバシー ・制限対象アプリの情報は端末内にのみ保存され、サーバーには送られません ・広告・トラッキングはありません ※ アプリの制限にはiPhoneのスクリーンタイム機能の許可が必要です。 ※ NFC解除には市販のNFCタグ(NTAG213など)が必要です。

Verdict
The clearest difference is in-app purchases: LockTag at none against Zentime's 7. LockTag also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
