Datata

Manage plans, not just usage

Free · In‑App Purchases

Travel eSIMs and everyday SIMs together. On-device estimates you can adjust against your carrier. Optional iCloud. Apple Watch can view and start or stop a session. Datata keeps your plans, cellular lines, and devices in one ledger. The home screen shows about how much is left and whether you are using it faster than planned. It fits when: - A yearly plan, a data pack, a travel eSIM, and an everyday line need to live together - Two SIMs use different plans, or one plan covers more than one line - You switch phones or use two devices and want the same ledger under one Apple Account, with optional sync - You check your carrier, then update the remaining amount in the app You can: - Keep more than one plan, with the remaining amount you confirmed and a second figure estimated on this iPhone - Link a plan to a line, or link one plan to several lines - Adjust the remaining amount when the estimate is off - Record a stretch of use on the Lock Screen and in the Dynamic Island - See remaining data in a Home Screen widget - On Apple Watch, see what is left and start or stop a recording (usage is still estimated on iPhone) - Optionally sync plans and confirmed usage with iCloud (on this iPhone only, unless you turn sync on) Figures come from on-device cellular sampling and your adjustments. They are for remaining data and pace. They are not a substitute for a carrier bill or the totals in Settings → Cellular. At important moments, check with your carrier and update the remaining amount in the app. The Apple Watch does not yet keep its own cellular ledger. The free tier covers 2 plans, with iCloud sync and viewing across devices. A one-time purchase, Datata Pro, unlocks more active plans and full features on additional devices. People who downloaded a TestFlight build before 0.1.0 (45) and opened it keep the full release.
