Datata keeps your data plans in one place. The home screen shows what's left and your pace. A good fit for: - Yearly plans, add-ons, travel eSIMs, and everyday lines together - A dual-SIM phone on different plans, or one plan across more than one line Closer the more you use it: - Update: estimates come from your device. Checking them against your carrier now and then keeps them closer - Session: see how much you use over one stretch of time, on the Lock Screen and in the Dynamic Island - On Apple Watch, start or stop a session. Usage is still estimated on iPhone More ways to follow along: - Widgets and custom alerts - A Shortcuts guide, so usage shows up sooner - Optional iCloud sync across your devices Datata Pro: - Free includes up to 2 active plans and iCloud sync. Other devices can view your plans. Enough for most people - Datata Pro is a one-time purchase: no limit on active plans, and your other devices can estimate for themselves, not only view
