120 builds
  1. Build 122
    • New filter sets: save your current filters under a name, with a suggested name such as “Rogers, Bell · n78” filled in, and switch between sets at the top of Filters.
    • On the map, touch and hold the Filters button to switch sets; when your filters match a saved set, its name appears above the search row.
    • After changing a set’s filters, update the set or save it as a new one from Filters. If the name is already used, choose Replace or Keep Both.
    • Filter sets sync with iCloud and are backed up with your favourites. On a keyboard, ⌘1–⌘9 switch to your first nine sets.
    • Search for a set’s name in Spotlight, or ask Siri “Apply [set name] in North Towers”, to open the map with that set’s filters. Sets are also available in the Shortcuts app.
    • Tap a database update notification to go straight to the database update page.
    • Filters counts and the map update faster with the full Canadian database, and site details open more smoothly.
    • Fixed a crash that could occur at launch. System alerts use their standard colours, and the search row no longer lights up under open menus.
  2. Build 121App Store release 1.0.1
    • Dragging the Filters sheet down no longer pauses after you select bands such as Canadian n77 R17.
    • Filters respond faster with the full Canadian database.
  3. Build 120
    • New Canadian n77 R17 band filter (3650–3980 MHz) finds sites whose n77/n78 channels overlap this range, and works with Any/All and your other filters (thanks to Jacob for the feedback and suggestions).
    • Tapping the Last reading card opens the Connected site page instead of starting Field Test again; use the read action for a new reading.
  4. Build 119
    • iPhone Duo inner display in landscape: the site panel’s content fills the panel even after it changes width, carrier names no longer break letter by letter, and Bands, Cells and detail pages use the full width.
    • Inner display flat in portrait: sites and tools open in the standard resizable sheet; tabletop keeps the panel below the fold.
    • Inner display in landscape: re-centre sits with the map controls, and the selected band card and the Apple Maps legal link are centred between the panel and the map controls.
    • Outer display: the band card matches the site sheet’s width, and folding with a site open no longer leaves the sheet stuck with a squeezed Bands list.
    • An eye button next to the coordinates hides or shows the coordinates and distance; touch and hold still works.
    • Canadian n77 notices are centred within band rows.
    • Quieter microwave lines with thinner dashes, softer carrier colours and smaller endpoint rings, plus compact round 6 GHz pins.
  5. Build 118
    • Connected site matching checks, in order: PLMN + TAC + Cell ID; TAC + Cell ID within 10 km; PLMN + Cell ID within 10 km; then Cell ID within 10 km.
    • Partial matches need a recent location, and ambiguous results stay unresolved instead of picking a site at random.
    • Older TAC-only results stay visible but are marked unverified until refreshed; your shortcut keeps working.
    • Redrawn microwave lines and endpoint labels, including at steep 3D viewing angles.
    • More compact Related sites and links, with clearer return destinations and record counts.
    • A compact Canadian n77/78 notice for frequencies above 3650 MHz, with a tappable explanation of the R17 device requirement (thanks to Jacob for the feedback and suggestions).

  7. Build 116
    • iPhone Duo support: layouts adapt to the outer display and the fully open inner display, in book and tabletop poses, in portrait and landscape.
    • Content and controls stay clear of the camera area, the fold and the system sidebars.
    • Explore fits search, filters, map layers, map controls and site panels to the available space. Site details move between a bottom sheet and a side workspace, and band diagrams and map framing follow the usable map area.
    • Favourites, Settings and Insights use the inner display with list-and-detail layouts, and keep a single column on narrower screens. Roaming networks, Carrier features and other Insights pages follow the available width.
    • Bands and cells, microwave and 6 GHz views, Look Around, database downloads, Help and Support have updated spacing and navigation on Duo.
    • Editors, search fields, SIM pickers, sheets and popovers adapt to the keyboard and the current pane; Back, Close and Done follow the system’s toolbar placement.
    • Folding, unfolding and rotating keep your map, selected site, open detail page and unfinished edits.
    • New Total bandwidth filter with optional minimum and maximum in MHz; overlapping ranges and repeated sectors are counted once.
