Note by Chat & Send Files
Read full descriptionHide full description
Most note apps are bloated. They make simple things complicated. We made SelfChatNote to do the opposite. — THINK IN STREAMS — Your mind doesn't work in folders and documents. It flows. SelfChatNote works the same way – just write what's on your mind, like texting yourself. Pin the important stuff. Archive what's done. Drag to rearrange. That's it. — TODOS WITHOUT ANOTHER APP — Why do you need a separate app for tasks? You don't. Write your todos alongside your thoughts. Flip to Todo View when you need to see everything. Check things off. Move on with your life. — SEND FILE QUICK — Sometimes dropping doesn't work. Sometimes you're on different networks. Sometimes your PC doesn't even support it. We get it. Send File Quick lets you move files between your desktop and phone without the headache. Scan a code, pick a file, done. No cables. No cloud uploads. No waiting for devices to "discover" each other. — MARKDOWN, IF YOU WANT — We support it. But we won't force it on you. Just type normally if that's your thing. — THE POINT — No clutter. No complexity. Just you and your thoughts, organized the way they naturally flow. Terms of Use: http://www.apple.com/legal/itunes/appstore/dev/stdeula

Turn your iPhone into an EMF detector and gauss meter. EMF Detector reads the built-in magnetometer and shows live magnetic field in microtesla, milligauss, or Gauss — the same units a handheld meter uses. This app measures magnetic fields. It does not measure Wi‑Fi, 5G, or ionizing radiation. What you can do • Live EMF detector with peak hold and average • Switch units: µT, mG, Gauss • Zero / calibrate to ignore Earth’s field and hunt nearby sources • Ghost hunt mode: audio and haptics on magnetic spikes (used by investigators as a starting point, not a spirit detector) • Metal and stud finder: sweep a wall to find studs, pipes and wiring • XYZ charts and field direction compass • Session log with CSV and PDF export Ghost hunt & metal Walk slowly. Zero the meter, then sweep. Spikes mean a changing magnetic field — speakers, transformers, studs, or wiring. Audio maps spike strength so you can hunt without watching the screen. Pro removes ads and unlocks direction, full history, high-EMF alerts, and PDF export.
