通信制限までの使用量を日割りで表示します。 今日までの予定使用量をグラフで表示。 そのグラフと比較できるように実績もグラフで表示。 今日時点で制限に対してオーバーしているのか、 余裕があるのか一目瞭然です。 さらにカレンダーで月初から本日までの日毎の使用量を表示しているので、使いすぎた日や余裕のあった日が確認できます。 また現在の通信量を元に残りの日々で、どれくらいの通信量が使用できるかも表示しています。 プラン変更の参考にもしてください! 前月以前の通信量も確認出来ます。 予定使用量をオーバーした場合に、オーバー量を バッジとアラートで通知します。 月末だけではなく10日、20日の締め日にも対応しています。 通信量の上限も1〜999GBに対応しています。 各社大容量データプランにも対応しています。 Apple Watchにも対応しています。 本日の使用量、本日までの予定使用量、本日までの実績使用量を表示します。 またコンプリケーションに通信量を表示することもできます。 ※通信量はアプリを初めて起動した日からの記録となります。 ※アプリを強制終了せずにバックグラウンドで待機している状態の方が、より正確に計測出来ます。

See your remaining data at a glance — right on your Home Screen. No ads. No subscription. No VPN. A data usage widget you can match to your carrier's numbers. TIRED OF… • Trackers that never match what your carrier says? • Ads, or features moved behind a subscription after you paid? • Apps that count Wi-Fi as mobile data? • Billing cycles stuck on the 1st? WHAT GIGAGUARD DOES • Calibrate to your carrier — on-device measurement always drifts a little. Type in the usage shown in your carrier's app and GigaGuard matches it. • Widgets for the Home Screen and Apple Watch (Lock Screen widgets with Premium), with a refresh button that updates without opening the app. • Cellular and Wi-Fi tracked separately — only mobile data counts toward your plan. • Any billing day from the 1st to the 31st, rollover data, and day passes for prepaid or travel eSIMs. • Pace forecast: see where you'll end the cycle and the day you'd hit your cap. • A daily limit alert, plus alerts at the percentages you choose (Premium). • Daily usage history, and per-cycle history (Premium). • Up to 20 lines — main, work and travel eSIM — each with its own plan (Premium). • Siri Shortcuts: "Check remaining data in GigaGuard". PRIVACY • No VPN. GigaGuard never sits in the middle of your connection. • No carrier login, no account. • Your data stays on your iPhone. Nothing is sent to a server. PRICING Free to use. Premium is a one-time purchase — never a subscription. No ads. PLEASE NOTE iOS doesn't let apps read your carrier's official usage, so GigaGuard measures on-device and lets you calibrate. Usage is updated when you open the app or refresh the widget. Per-app usage is not available. For billing, always check your carrier's official app or website.

Verdict
The clearest difference is in-app purchases: 日割り通信量 at none against GigaGuard's 1. 日割り通信量 also leads on iOS requirement (14.4 vs 17.0). GigaGuard's advantage is ads (none vs shown) and update cadence (every 5 days vs every 3 weeks). On price and device support there is nothing between them.
