Great ideas. Another easy win is to strip your home screen: move all infinite‑scroll apps off it hide notification badges, and keep one bare page with only school/family tools so reflex taps hit a dead end. Flip on grayscale during study hours or evenings; it makes feeds feel dull fast. Also pick a parking spot for your phone during work blocks (face down, out of arm’s reach) so you break the constant checking loop.
No subscriptions. Phone auto-syncs to a home box with Syncthing over Wi‑Fi, then a script de-duplicates and the phone clears local copies once the hash matches. External drive holds two rotating backups. I export a small JPEG set for quick browsing.
