Simple home tests for indication sleep apnea?

Anything new on the market or discovered to be a good indicator?

Possibly. At the very least, you may experience was is called 'hypopnea', which is one of the components in the AHI or the 'apnea/hypopnea index'. AHI is what the medical field uses to establish one's need for intervention. If the count is higher than 5 events per hour, or in any one hour, it could indicate a need for PAP use.

As the person who just replied to you has suggested, the gold standard is an over-night sleep lab, the procedure called a 'polysomnography', where you get a gajillion electric leads placed all over your body, including onto your scalp and legs, and you try to sleep so that you can be monitored. I developed atrial fibrillation (AF) and it was the last diagnostic step proposed by my cardiologist. The result was 'severe sleep apnea', which is when one had 30 events each hour or more. I was counted at 31 events.

Do you know when you developed the apnea?

Unfortunately, I have no idea. My wife had told me I snored some for a couple of years. The summer I first developed AF, I went to help my SIL and my daughter set up their remote cabin. We all slept in the same building, and my daughter said I snored all night. The polysomnography came about four months later.

Is it possible to determine sleep apnea from a recording of sounds while sleeping, like holding or gasping for breathe? Are these reliable signs?

Not as far as I know, but it isn't inconceivable. As far as I am aware, only a blood O2 sat monitor, say a finger sensor, maybe a 'snore app' listening to you all night (snoring is associated with sleep apnea), and some kind of heart rate and rhythm monitor are about all that might paint a coherent picture. Otherwise, it's a sleep lab or some other device and leads/sensors. The most reliable way is to actually measure the rate and volume in breathing, and that means a mask, fitted reasonably well, to measure tidal volume, flow limitations, etc.
If you know for a fact, or if a partner reports to you, that you gurgle, snark, gasp, and otherwise seem to starve for air routinely each hour when you sleep, then yes, but the experts prescribing care need to know veridical numbers.

I don’t know about them providing any diagnosis, but the apps can record and rate your snoring, Snore Lab is one such app. It picks up on everything. So, if you fluff your pillow, it’ll show as noise.

It may help you know whether you snore or gasp for breath while sleeping if you sleep alone.

If you sleep 8 hours a night but a snore app indicates you snore fairly loudly a total of 2 hours during your sleep is this indicative of sleep apnea?

I know Sleepscore is not a diagnostic tool but would scores about 75 indicate low chance of apnea? What is deep sleep and rem sleep is very high?
