That's just what I've been doing after deleting Instagram from my. phone. I can't trust my evening dopamine-seeking behaviour with the phone app, but there's much much less stickiness in the browser.
I could possibly uninstall everything but the absolute necessities on a smartphone for when I need it, and otherwise carry a flip phone. Maybe use the flip phone for tethering so the smartphone doesn't need a Sim card. But it seems that might be introducing lot of extra stress into my life, especially for stressful jobs like parking before a meeting, keeping up to date with clients, etc
