IOWODO R30Pro smart watch is a good smart watch for monitoring important exercising data, health data, sleep data, ect. However, if you want to set the time you'd have to use "Da Fit" app. You also have to use "Da Fit" app for calls, texting (receiving texts), ect.
Why you need the app, is for using your mobile phone to make/receive calls, texting (receiving texts) and weather. Climate conditions are for you to select. That be where you live or a location that impresses you. Weather for a week ahead is listed as is the current climate conditions. However, excluding calls, climate and receiving texts, an app is not necessary.
To make/receive calls (Get Smart) you need bluetooth. Of course, that means you need your smart phone within 30 feet. If it's further away your smart watch won't work as a phone. However, if you make/receive calls using your smart watch you don't have to get up to get your smart phone. Same applies if you take your smart phone with you everywhere. The lazy persons perfect tool.
As with all smart watches this smart watch is not 100% accurate. It's close yet not accurate. It has the solution to 30 or more exercises. It shows how many calories are burned when skipping rope, jogging, bicycling, ect. And an app is not necessary!
There's a button below the main button you press to see a list of exercises. Select the exercise you want's to do. After your workout or workouts, you can find the data for each workout by pushing the main button which displays time and weather then push it again. It shows a list from Activity to Settings.
Select "Exercise Records" to see data for each of your workouts. Usually 3 to 5 workouts are included. Select each workout displayed to keep track of how long you worked out for and calories burned. You have the selection of deleting your workout sessions.
To monitor Blood Oxygen, BPM and Stress is easy and also does not require an app. For the data to show correctly on the app, you must first click on Blood Oxygen (SpO2), Heart Rate (BPM) and Stress. Wait until you hear a low sound. Those sounds indicate the tests concluded. Each will show on the app afterwards. First they appear on the smart watch.
Monitoring sleep data also does not require an app. I'm nocturnal or I'm usually up between 10:00 p.m. and 6:00 a.m. To exclude people who work between 10:00 p.m. and 6:00 a.m. is wrong!
At first I could not use the sleep data. However, I changed the time on my phone to 10 p.m. when it was 6 a.m. That corrected the discrepancy. On the 'Da Fit' app you'll be confused by it's info. It actually tells you when you fall a sleep. However, the watch starts obeserving your sleep soon after you go to bed.
Look for the times when you fall asleep and get up and how long you slept. It might confuse you. For example, the watch showed an 8 hour 37 minute sleep, between 11:07 p.m. and 10:26 a.m. The time I slept for was nearly correct. I excluded the first sleep stage which was long and the time I was up which was also long.
Though I could not correctly time the sleep, the app was very helpful. Of the 11 hours 19 minutes I was in bed, I subtracted 2 hours 42 minutes to obtain the length of the first sleep stage (I was up) and the time I awoke then slept again. It took considerable time to sleep again.
About 5 to 10 minutes or more must be subtracted if you notice your watch continues adding time to your sleep if you're in bed. It will continue to record sleep after your up, so to stop that take the watch off if you're still in bed.
Look for the first sleep stage which is light sleep. If you notice your sleep data is incorrect always look for the first sleep stage. You can correctly learn your sleep by excluding the first sleep stage if you notice discrepancies. Also time you awake then sleep again.
They need to improve their app. However, you can correct or learn how much sleep you obtained by using the first sleep stage and awake time.
It does display how long you were up if you awake during sleep. It does not tell you how long you were up for however.
Deep sleep, light sleep and REM sleep are displayed with each display showing how long you were in each stage. Perhaps their app will display awake time soon.
You can't set the time on the watch without the app. That really agitates me. For that reason, a 4 rating instead of a 5, did I approve.
The IOWODO R30Pro Smart Watch is a good selection for average folks. Been using it for over a month and like the smart watch. Unfortunately, an exception was made by the manufacturers to exclude a 24 hour sleep schedule. However, as written, you can correct by changing the time on your mobile phone.
