On a phone, game-page range and estimate horizon are dropdowns so they are not cut off. Estimates stands out as its own control. The PNG save is an icon and stays readable at a narrow width.
The filter panel is quieter: short profile id, icon refresh, and one line for how many owned titles are on this catalog. Steam Deck chips are shorter.
Add missing titles from a public profile now reaches the catalog. Website only, short-lived cookie, not a published API. Up to 40 ids at a time, three times per hour. They appear after Steam pages are fetched.
Library import is a website feature, not a published API. It needs the short-lived site cookie; a script without it is refused. After a successful paste, Refresh reloads from that public profile. Ids stay on this device. The steamid is not stored.
Privacy, Disclaimer, and the FAQ say the same: six imports per hour per address, and that overlay is not listed for callers of the public API.
Game pages put in-game now, 24h peak, and all-time peak on the player chart panel, with a taller plot and a PNG you can save. Sampled-from Steam stays in the corner. No store artwork in that image. On a phone the three stats share one row, and range plus the estimate horizon are dropdowns. Estimates is its own toggle. The PNG save is an icon next to it.
Paste a public Steam profile to overlay owned and wishlist ids on charts and deals. Ids stay on this device. The last successful paste is remembered here so you can refresh without retyping. The steamid is not stored. Six imports per hour per address.
Charts has a Movers table: titles above their typical hour of the week after the stored week shape, not raw percent on a quiet tail.
Cards can show a day's worth of new reviews, from a snapshot of all-time totals, and a launcher line when Steam's store fields name one (Requires EA App, not a Denuvo scan).
The chart shows Rising, Falling, or Holding from the slope of sampled hours, and a compact likely range instead of a clock-precise peak.
