DataFastView

Your iPhone is measuring itself all day. DataFastView is where you get to see it.

Live Wi-Fi quality, battery, CPU, memory, storage and the weather — in the Dynamic Island, on the Home Screen, in Control Center, and on one screen inside the app. Everything is measured on the device. There is no account, no tracking, and nothing to sign up for.


WI-FI QUALITY, NOT SIGNAL BARS

A full-bar connection with 300 ms of jitter is a bad connection, and the bars will never tell you. DataFastView scores your link from 0 to 100 using four things it measures directly:

• Round-trip time to your own router
• Round-trip time to the internet
• Jitter — how much that time varies
• Packet loss

Live upload and download rates sit next to the score, and a download-speed test runs only when you tap the button. Tap "How this score is measured" to see exactly how the four are weighted. Nothing is hidden behind a marketing number.


ENERGY AND SYSTEM

Battery level and charging state, Low Power Mode, and thermal state — Normal, Elevated, High or Critical. CPU on a fixed 0-100% scale, so a phone idling at 3% does not draw the same mountain as one at 100%. Memory split into active, wired, compressed and free. Free storage and time since the last restart.

There is no battery temperature, health or cycle count, because iOS publishes no public API for any of them. Any app showing you those is estimating. This one tells you what it actually knows.


THE DYNAMIC ISLAND

Choose one metric for the left side and one for the right, from CPU, memory in MB or percent, storage in GB or percent, uptime, battery, thermal state, network rates, Wi-Fi quality, or a clock that keeps ticking on its own. Every option shows its live value while you pick, so you are choosing from real numbers rather than names.


WIDGETS

Actions (medium) — up to ten launch buttons of your own, in two rows of five, each with a symbol or a real app icon and a colour you choose. Load a screenshot of your wallpaper and the widget reads as transparent.

Storage and network (small) — a ring of used space, free and used in GB, and the last Wi-Fi reading.

Weather (large) — current conditions, temperature, feels-like and the next five days, in the app's own palette. Weather data provided by Apple Weather.

There are Control Center controls too, and rotating phrases on the Lock Screen.


WEATHER

Current conditions, the next hours and the next days, with a two-day temperature trend on the Now tab that marks every peak and trough. Location is used only to ask for the forecast where you are, and only while you are using the app.


TOOLS

A password generator that runs entirely on the device, using the system's cryptographic random source. Set the length and character classes, exclude look-alike characters (O 0 I l 1) and keyboard runs (abc, 123, qwe), and read the real strength in bits of entropy. Nothing is stored, nothing is sent, and the clipboard copy expires.


PRIVACY

No account. No analytics. No advertising. No third-party SDKs. The app has no server, so there is nowhere for your data to go. Everything you configure lives on your iPhone and disappears when you delete the app.


ONE PAYMENT

Buy it once. No subscription, no trial that turns into a bill, no in-app purchases.
