CommuniPhone is an honest, at-a-glance health dashboard for your iPhone and iPad. See exactly how your device is doing right now — storage, memory, battery, temperature, CPU, and network — with clean live gauges and a single overall Device Health Score. What CommuniPhone shows you: - Storage: how much space is actually free, with a trend chart so you can see it filling up before it becomes a problem, plus guidance on how to reclaim space. - Battery & Power: charge level, charging state, and Low Power Mode, alongside how warm your device is running. - Memory & CPU: how much RAM your device has, how much CommuniPhone itself uses, and how hard the processor is working — including 1, 5, and 15-minute load averages and per-core activity. - Thermal: a live temperature status that most monitors ignore, so you know when your device is running hot. - System: network data counters, your local and external IP address, and a full device spec sheet (model, chip, screen, iOS version). Trends and alerts: CommuniPhone quietly logs these readings on your device so you get trend charts over time, and while it is open it can alert you when storage runs low, the device gets hot, or the battery is low — always with plain-language guidance on what to do next. Honest by design: CommuniPhone is a monitor, not a "cleaner." iOS intentionally prevents any app from seeing or controlling other apps, so CommuniPhone will never pretend to "boost," "free RAM," or close apps for you. It shows you real, device-level information and helps you understand it. Your readings are processed on your device and are never uploaded; the app itself uses the network for ads, remote config and anonymous usage analytics, like the rest of our free apps. CommuniPhone is 100% free for everyone, supported by ads: after a free first day, watching one short ad unlocks the app for 12 hours at a time. No subscriptions and no in-app purchases — every feature, including trends, alerts, the full spec sheet, and copy/share, is available to every user. Have an idea or found a bug? Request features and suggest improvements right from the in-app CommuniDev tab — we keep the app free for everyone, forever.
