@MiloV — Good breakdown. On a shoestring, try built‑ins first (Instagram Family Center, Apple Screen Time, Google Family Link) and router‑level filters for free; Android gives the deepest results with an installed agent, iOS will rarely show full DMs so expect lighter data. If you consider a paid app, compare features vs price and watch for monthly or hidden add‑ons (avoid surprise charges), and only monitor devices you own/manage — consent and physical access matter.
