I hope my apps are useful to your SMART Life. Thank you.
** No internet support : You can open this app without any connection. After installation, open the app 2-3 times with your device connect to WI-FI or a 3G/4G connection.
** This app does not support the devices that have NO magnetic sensor (e.g HTC Desire V, ST21i, Micromax).
** Remove and freeze adBlock app. It causes the licensing failure.
** Google has recommended this app as one of the essential apps of Google Play for Education.
Remotely access your video camera, digital video recorder, network recorder and webcam.
Over 1900+ devices supported. Use Scan Camera to automatically find compatible driver.
New! Android Wear and multiple TV platform support.
Built-in web server enables remote control of the app to change record mode settings away from home or for use as a video wall or function as a transcoder to fetch frames from devices with proprietary protocols.
Motion Detection built into app works with all cameras. Play sound when motion is detected. Record only when motion is detected in Record Mode (email notification optional).
Record Mode that turns any spare Android device into a solid state, battery backed 24/7 video recorder for your standalone IP cameras. Allows playback, search and export to video clip file.
Background Audio Mode keeps playing audio even when you switch away to other apps or lock the screen for use as baby monitor.
With 5+ years of development there are so many features they won't let me describe them properly so here's an overview.
Wide protocol and video format support including HTTPS, RTSP and ONVIF.
Features include matrix view, pan tilt zoom, home/lock screen widgets, grouping, encryption and in-app motion detection.
Upgrade features include 2-way audio, background audio, record mode with remote control and notifications.
This rangefinder(telemeter) measures the distance and height of a target with your phone by trigonometry.
Usage is simple : just stand up and press the shutter. The important point is aiming the camera at the GROUND, NOT the object. (i.e. In order to measure the distance from someone, aim at his shoes.)
If it is inaccurate, please read the instructions in this app or see the checklist diagram in the blog. Because the sensors on your phone can be changed depending on OS version, firmware and battery status. You can calibrate them with the calibrate menu and settings for yourself.
* Now, 3 tools for distance were completed.
1) Smart Ruler (short, touch) : 1-50cm

Compass PRO is the compass in your pocket, when you need it, where you need it.
Compass PRO has the following functions:
- Shows direction of north, south, east and west
- Shows degrees in “side window”
- Rotating bezel
HOW TO USE COMPASS PRO?
First we’ll need to cover a little bit of compass jargon first. The part of Compass PRO that moves and always points north is called the card (with N,S,E, and W indicated, and a beveled edge with a series of numbers on it). There is a movable ring around the edge of the compass, called the bezel. A red double line across the top of the compass is called the lubber line, and finally, there is a little window above the compass which is often named as side-window (as it is on the side of a real compass).
Side-window navigation couldn’t be simpler. You point the lubber line on top of your compass at where you want to go. Now as long as you hold your compass flat in front of you with the lubber line pointing in the direction you’re going, you should always see the same number in your window as long as you’re going the right way. If you see a different number, turn until you see the same number.
The downside of the side window method is that you need to remember your number.
Navigating with bezel works essentially the same as using the side window, but your bezel remembers your number for you. All you do is, point the lubber line on top of your compass at where you want to go, and then wait until the card settles down and stops moving. Then turn your bezel until the double triangle on the edge of the bezel (the notch right by the number zero on the bezel) is bracketing the north arrow on the card. Now as long as you hold your compass flat in front of you with the lubber line pointing in the direction you’re going, you should always see the north arrow inside the notch, as long as you’re going the right way. If not, turn until you see the north arrow inside the notch.
Notice that if you’ve adjusted the bezel correctly, the number in the side window is also the number directly across from you at the front end of the lubber line. In other words, if you turned the bezel counterclockwise until the notch bracketed the north arrow, the 120 on the bezel would be at the far end of the lubber line. Notice that on the card, the number showing in the side window is 120. If you were holding this compass and going in the direction of the lubber line, you’d be on a heading of 120.
Now you should have learned how to go to desired direction. But how do you get back? Easy! If you’re thinking in terms of the bezel, simply turn until the north arrow faces not to the notch, but to the single triangle that’s exactly across from the notch. Now you’re pointed back where you came.
The really tricky part of using your compass isn’t learning what the numbers mean and how to adjust the bezel. The most common mistakes are not holding your compass flat, and not actually going in the direction your lubber line is pointing.
Large iron and steel objects can influence the magnetic sensor in your Android device, causing it to point in the wrong direction. This is called deviation. If you suspect this is happening, simply move away from the object several feet and the problem should correct itself.
