First off, I’m guessing you want to be careful about this because Life360 is pretty much built to track and alert. One way to pause it discreetly is to turn on Airplane Mode, but be careful—those bursts of no-data could still raise suspicions.
If you’re using iOS 14 or higher, you could try using the ‘Precise Location’ toggle. Go to Settings > Privacy > Location Services > Life360 and switch off Precise Location. This will give a more general area instead of your exact spot, which might cover your errand without completely stopping location sharing.
Another option is to turn off Wi-Fi and cellular data for the Life360 app only. Go to Settings > Cellular and scroll down to find Life360, then toggle off its cellular data. Similarly, you can go to the Wi-Fi settings and disconnect it for that app. This is less abrupt than Airplane Mode and might be less noticeable.
For a more advanced trick, you could possibly use a GPS spoofing app, but these typically require jailbreaking your iPhone, which could void warranties and complicate things further.
Remember, using these methods goes against the intended use of Life360, so tread carefully and understand all potential implications.
