6.     track.pngTracker

a.       Example: Family locater by Life360

Give your Family Peace of Mind

Life360 runs on your mobile device to allow you to view your family members on a map, communicate with them, and receive alerts when your loved ones arrive at home, school or work.

Answer an age-old question: Where are you?

Our research shows that 6 to 8 text messages a day are dedicated to this question. Why not just open the Life360 map and answer it for yourself?

Check in for quick updates

You made it to the soccer game, the poker tournament, or Aunt Millie’s house. Avoid the "Did you arrive okay?" phone call. Check in instead. (Have an emergency? There’s a button for that, too.)

It's the 21st century: automate

Life360 Places lets you save your favorite locations so that friends and family will get automatic alerts when you come and go. Sure, it’s a lazy way to check in, but it’s effective!

Group your connections

Keep family & friends separate with Circles. We default to the Family Circle, but you’ll want to create more for the other people in your life. Aunts & Uncles, perhaps? Babysitters? Dog walkers? Marathon pace team? There are many scenarios where location sharing comes in handy.

Keep everything in its place

Messaging, location sharing, and check-ins are all Circle specific, so no one will see anything they don’t need to.

You're the boss

When you create a Circle, you get to decide who is invited and who isn't. We know how important privacy is.

You're in control

Location sharing is up to you. Not everyone needs to know where you are at all times. Location sharing is specific to each Circle, and you can turn it off and on whenever you want. But we always let the Circle know - just so others can make sure you're still safe.

Easily chat with family members

Locations are standard, but what about locations AND messages? You can talk to family members while knowing where they are.

More customization than ever before

As Life360 has evolved, we’ve done everything we can to put you in the driver’s seat. You control the invites, you control when you share your location, you control who goes in what Circle and you decide which Places you’re going to save.

10. Heart Rate Measurement

a.       Example Heart Rate Monitor by REPS

Heart rate or heartbeat is an important measure in health and fitness. Using Accurate Heart Rate Monitor app, you can now measure and monitor your heart rate!

Incredibly accurate in measuring your heartbeat
Free with unlimited recording
Easy to use with intuitive design
Identifies heart rate training zones (Rest, Fat burn, Cardio, and Peak)
Google Fit support
Estimates calorie burnt per hour
No additional hardware required

How to use the heart rate monitor free app to measure your heartbeat?

To use this heartbeat counter, just put your finger on the phone's camera and stay still, the heart rate is shown after few seconds. Covering a part of flash may help heartbeat counter to become even more accurate.

What is a normal heart rate or heartbeat?

According to Mayo Clinic, a normal resting heart beat rate for adults ranges from 60 to 100 beats per minute (BPM). However, keep in mind that many factors can influence the heart rate, including Activity level, Fitness level, Body size, Emotion, etc. Generally, a lower heartbeat at rest implies more efficient heart function and better cardiovascular fitness.

Consult your doctor if your resting heartbeat is consistently above 100 beats per minute or if you're not a trained athlete and your resting heartbeat is below 60 beats a minute

What are heart rate training zones?

Heart rate training zones are calculated using maximum heart Rate (MaxHR). Within each training zone, subtle physiological effects take place to enhance your fitness. We have a similar definition to those used in Fitbit trackers:

- REST ZONE (up to 50% HRmax): This considers as resting zone.

- FAT BURN ZONE (50 to 70% of maximum): Recovery and warming up exercises should be completed in this zone. It’s called the fat burn zone because a higher percentage of calories are burnt from fat.

- CARDIO ZONE (70% to 85% of HRmax): Most of the main exercise should be completed in this zone.

- PEAK ZONE (greater than 85% of HRmax): This zone is ideal for short intense sessions (high-intensity interval training HIIT) to improve performance and speed.

This heart rate monitor app calculates and automatically saves your heart rate training zones.


- Heart rate monitor app should not be used as a medical device.
- In some devices, heart rate monitor may make the LED flash very hot.

19. Function Generator

a.       Example: Function Generator by keuwlsoft

function2.pngCover artDual channel function / waveform / signal generator for the speaker / headphone audio output.

No Ads, No Permissions, No In App Purchasing, No Limited Features. Full Version.

Output is 16 bit for each left and right channels and at 44.1kHz. Output will depend on your device hardware. Some device hardware may may filter out the DC bias and low frequency signals. At high frequencies, the waveforms will be distorted due to limited number of samples for each waveform (for example at 4.41kHz, a sine waveform will be approximated by only 10 points). Therefore this is for fun/educational use, for critical applications use a real calibrated function generator.

Left and Right audio channels can be assigned to either channel 1 or channel 2.
Sine, Square & Triangular waveforms.
Frequency range from 1 mHz up to 22 kHz.
Amplitude as percentage 0-100%.
Set duty for square waveforms or skew triangular waveforms to get saw waveforms.
Offset the phase of waveforms.
Sweep frequency or amplitude (Single, Repeat & Bounce modes).
Amplitude Modulation (AM).
Frequency Modulation (FM).
Burst mode for a specific number of waveforms (1-10000).
White noise & pink noise Generator. Pink (1/f) noise falls of at ~3dB per octave between 43 Hz and 44 kHz.
Memory slots to save & recall channel configuration.
Select values with spring slider or number pad.
