If you plug into the power and switch on development mode, there is an
option.

I have various Apps on my phone which can keep the screen alive.
SatNav and speedometer for example.
Google Maps when navigating.

Is it possible to set other Apps to keep the screen alive all the time
when in use?

Cheers

I agree with Richmond that Developer Options "Stay Awake" is one option,
but, as noted, it only works when the phone is connected to USB power.

It's also possible for some apps on Android to keep the screen awake,
but only if the app itself requests the "keep screen on" permission.

Apps like Google Maps or speedometer apps do this automatically. Other apps
may not, so the screen may time out normally, unless you use a workaround.

Here are the main workarounds I'm aware of, but I haven't tested them.

1. Increase the system screen timeout
This affects all apps. Set a long timeout (for example 10 or 30
minutes) in Settings. Combine it with Smart Lock if you want the
phone to stay unlocked while in use.

2. Developer Options "Stay awake"
Enable Developer Options, then turn on "Stay awake". This keeps the
screen on but only while the phone is connected to USB power.

Supposedly Pixels have a quick-settings tile, but I can't test that.

3. Use a third-party "keep screen on" utility
Looking it up, apps such as "Caffeine" or "Wakey" supposedly can
force the screen to stay awake. Some of these may allow per-app
rules so the screen stays on only when a chosen app is in the
foreground, but I haven't personally tested any of these apps.
Caffeine <https://lab.zhs.moe/caffeine/>
<https://play.google.com/store/apps/details?id=moe.zhs.caffeine>
Wakey (contains ads so I don't recommend it)
<https://play.google.com/store/apps/details?id=com.doublep.wakey>

4. Check the app's own settings
Some apps include an option like "Keep screen on" or "Prevent sleep".
If the developer added it, you can enable it there.

5. Automation (advanced)
Tools like Tasker/Automate supposedly might force an app to keep
the screen awake, but I haven't tested this, so that's conjecture.

There may be others as I have not tested this, but if the OP does
test this for the team, it would be useful to learn from his results.

Thank you for such a comprehensive response.

When I get the time to test this I will report back.

The App I have in mind is Freestyle LibreLink which displays the estimated blood glucose (BG) level derived from a sensor stuck to the arm.
It seems sensible to keep that awake when driving to guard against major unrecognised excursions in BG level.
It could be even more helpful for insulin users who are more at risk of hypoglycaemia.

Use in a car makes USB power trivial.
On a bike (pedal) a power bank would also be relatively easy to rig up.

All I need now is a Round Tuit.

Cheers
