Granum is a shotgun patterning companion for clay and field shooters. Photograph your pattern board after each session and Granum turns it into calibrated, comparable data - pellet counts, spread diameters, equipment records, and choke recommendations. PATTERN ANALYSIS Draw two concentric circles on your photo to define the main spread and scatter zones, then calibrate to real-world size by tracing a reference line. Every result is stored against the gun, choke, and load you were using, in millimetres or inches. The enhancement pipeline crops, lifts contrast on faded cardboard, and tunes detection sensitivity first. Pellet detection then finds the impacts automatically. EQUIPMENT Log every gun, choke, and ammunition load in full detail - barrel and stock specs, chamber sizes, choke constriction, powder charges, wads, hulls, primers, lot numbers, and cost per box. Reloads get their own section, and any item can carry photos. CHOKE CALCULATOR (PRO) Enter a target distance and desired spread, and Granum ranks every choke by predicted match quality. Your own recorded data always takes priority over generic estimates. CHOKE COMPARISON (PRO) Compare pattern performance across chokes in one table, filtered by gun and ammunition, to see which delivers the tightest or most consistent spread at your distance. SPREAD CHART (PRO) An interactive spread-vs-distance curve with your own data overlaid as scatter points. Drag to read exact values at any distance. FIELD NOTES No time for a full analysis? Record choke, distance, and observed spread in seconds. Field notes feed the choke calculator alongside full pattern data. LIBRARY Every pattern and field note in one searchable list, filterable by distance, temperature, location, weather, gun, choke, ammunition, date, and rating, in grid or list view. SCENARIO PLANNER (PRO) Lay out IPSC targets at real-world scale and overlay a calibrated pattern - or an averaged pattern group - to see what your spread and scatter zones actually cover at a given distance. Paper targets, plates, and poppers at any custom size. SHELL PLANS (PRO) Plan your rig before you shoot. Build a shooting order shell by shell, or let the loading-order calculator work it out from your starting load, reload batches, and any special shells. You get a colour-coded, numbered rig grid you can drag to fine-tune, with an optional overfill warning. PATTERN GROUPS (PRO) Group patterns shot with the same setup and compare averaged results instead of single shots. CLOUD BACKUP (PRO) Automatic backup to iCloud after every save, one-tap restore to a new device, and local .granum export for offline archiving. GRANUM PRO Photographing, analysing, and logging your patterns is free. A Granum Pro subscription unlocks the features marked above. Subscriptions renew automatically and can be cancelled at any time in your store account. MORE Share any pattern as a clean image card with rings, a centre-of-impact crosshair, and key metrics. Custom overlay colours throughout. Metric or imperial from a single setting. Crash reporting opt-out - no account required, and no data leaves your device unless you enable cloud backup. Dark and light modes tuned for outdoor readability. Whether you're testing loads for sporting clays, evaluating chokes for a hunting season, or building a long-term ballistic log, Granum gives every range visit a permanent, measurable record.

Tapping the selected item cycles down through everything stacked there, wrapping back to the top. • One finger on empty canvas now pans the view, and double-tap zooms to the point you tapped. • Snap to grid is now its own toggle, off by default - grid spacing and snap are remembered across sessions. • Target dragging is smoother, and the bottom sheet opens only when you tap a target or overlay, not when you drag one. • Rings reaching past the edge of a board photo no longer leave an empty box inside the overlay. PATTERNS • New patterns preselect your last setup - gun, ammo, choke, target type and distance carry over from your most recent pattern. • Prepare Image is a one-step crop screen: drag the corners and tap Apply crop. • Calibration distance now prefills from the target type or your last calibrated pattern. • Pattern detail highlights and Analysis Results are reworked into a labelled list with info legends. • Tap a pattern's photo, or its magnify button, to zoom and pan it full-screen. When the pattern has been analysed, its spread and scatter rings are drawn over the photo and zoom with it, with a toggle to hide them. • Share card photos fill the frame instead of leaving bars, and group share cards show the cover pattern's own spread and scatter rings. GEAR • Ammunition gets a Load Type picker (Birdshot, Buckshot, Slug) with quick-pick presets for shot size, payload, velocity, wad and crimp. • Choke constriction quick picks (Cyl through XF) fill in the name, and choke type, material and compatible gauges are quick-pick chips. • The choke detail screen shows an Expected Spread card at 20/30/40 m or yd from the Spread Chart model; adjusting it to this choke's own recorded patterns is a Pro feature. • Gear forms now confirm before you leave with unsaved changes. SHELL PLANS • Plan a detachable magazine feed instead of a tube: a chamber round plus magazines of up to 10 shells fire in sequence, and a magazine can be swapped before it runs dry. • Calculator overrides now accept a shot range, like 7-10, instead of one shot at a time. CUSTOMIZATION • Choose which measurements appear in a pattern's or group's highlights strip and share card, independently for each. FIXES • Fixed Pro purchases, restores and entitlement checks failing with an invalid key error - production builds since 1.14.1 shipped a broken subscription key, so buying Pro or restoring past purchases failed for anyone who hadn't already unlocked it. • Fixed a crash when dragging the calibration line or a spread circle on a new analysis. • Fixed pattern density and evenness never being recorded, which left those stats blank on the detail screen and in group averages. • Fixed scenario taps and drags: taps not reliably opening the edit sheet, pinch-zoom and pan fighting each other, distance lines measuring from unrotated bounding boxes, and dragging an overlay opening the target underneath. • Fixed the scenario export ignoring your zoom, the toolbar overflowing on narrow screens, its share actions vanishing while something was selected, and the name field's caret jumping to the start while typing. • Fixed the pattern library losing your sort on Field Notes, the diameter sign not rendering in overlay labels, and 0°C, calm wind or 0% humidity hiding a pattern's conditions. • Fixed a shell plan's rig grid and Shooting Order list drifting apart, and tube reloads of more than 4 shells firing out of order. ### 1.14.0 — 2026-09-13 DETECTION • Detection now reads the cropped photo itself instead of the black-and-white preview, so holes the preview missed are no longer lost and the sensitivity slider does what it says. • Every impact found is marked on the photo, and the counts follow the circles as you move them. Impacts outside both circles are drawn in their own colour and not counted. • Hole direction is measured rather than guessed, so a pale tear in kraft board is found as readily as a dark hole in white card, and a backlit target with both kinds is recognised. • Card grain is told apart from real holes by how deep a mark goes, and a run that throws shapes away says how many and why. • Processing resolution is chosen for you from the calibration and pellet size, and detection uses half the memory it did, so large photos no longer run older phones out of memory. • Detection shows which step it is on and can be stopped. ANALYSIS • All detection settings live on the analysis sheet and save with the pattern. Sensitivity sits up front; contrast, direction and cleanup are under Advanced. • Pellet counts can be typed or cleared by hand. • The canvas view button names its view - Photo, B&W or Uncropped - and the B&W view reflects the settings in force. • Leaving with unsaved work asks first however you leave, including a back gesture. SCENARIO • A holo sight reticle can be shown on any pattern overlay with a recorded distance, sized in MOA against that distance. Dot size, ring size and colour are set once in Customization. SHARING • Share cards export at 1080px wide in a fixed 3:4 frame, with the date, the conditions and the pattern percentage drawn as a circle on the photo. • Guns are named by make and model on share cards and scenario exports, never by nickname or serial number, and chokes and ammunition by their full names. CUSTOMIZATION • Impact marker colours and size, with a live preview. • A master switch for haptic feedback. • The pattern library's opening sort, or remember the last one. • Home layout: hide the latest-session card or the stats row, or pin the card to a pattern or group. FIXES • Fixed sharing a pattern or group and exporting a scenario failing every time. • Fixed name and distance labels being cut off at the edges of an exported scenario. • Fixed pellet counts measuring against a squashed circle on non-square photos. ### 1.12.0 — 2026-09-02 CUSTOMIZATION • New Customization page in Settings collects theme, date and time format, overlay colours and the Home quick access tools in one place. • The Home screen's Quick Access section is now yours to choose - pick any of the Plan hub tools. • Scenario overlay opacity is adjustable: a master opacity, the scatter-zone dim and a ring opacity multiplier, so an overlay can be read against whatever target it covers. SCENARIOS • Pattern overlays are labelled with gun, ammunition and choke everywhere they appear - on the canvas, in the picker sheet and in the spread banner. • The overlay picker now opens ordered from the most open choke to the tightest, and remembers your sort, grouping and filters between sessions. • New 15 cm square plate target preset. CHARTS • Spread chart own-data can be filtered by gun and load, so a choke's patterns from different guns no longer bury the trend. BACKUP • Granum now opens .granum backup files directly from Files, Downloads or a mail attachment. CHANGES • AI Analysis is no longer available on iOS. • Weather auto-fetch is no longer available on iOS. Weather is still recorded, just entered by hand. • Granum no longer asks for microphone, Face ID or location access. • Terms of Use and Privacy Policy are now linked from the subscription screen itself. FIXES • Fixed a crash when the app queried the database during a restore, reset or demo import. • Fixed dragging or tapping the top row of a shell plan rig grabbing the shell below it. • Fixed the shells already in your gun being given rig slots you are not carrying, and added a warning when they do not all use the same ammunition. • Fixed the library filter sheet's buttons sitting behind the system navigation bar. • Fixed the overlay picker's sort menu refusing to reopen after a selection. ### 1.9.0 — 2026-08-13 No release notes. ## Apps similar to Granum | App | Rating | Price | Category | | --- | --- | --- | --- | | [ShotCard](https://appshunter.io/ios/app/shotcard/id6754633811) | — | Free | Sports | | [Claycard Pro: Clay Shooting](https://appshunter.io/ios/app/claycard-pro-clay-shooting/id6795154740) | — | Free | Sports | | [Clay Shooter](https://appshunter.io/ios/app/clay-shooter/id6762271703) | — | Free | Sports | | [Shooting Stats](https://appshunter.io/ios/app/shooting-stats/id6743804285) | — | Free | Sports | | [Clays Scorer: Trap & Skeet](https://appshunter.io/ios/app/clays-scorer-trap-and-skeet/id6762514523) | 5.0 (2) | Free | Sports | | [Chairgun Elite Ballistic Tool+](https://appshunter.io/ios/app/chairgun-elite-ballistic-tool-plus/id1575685449) | 4.5 (393) | Free | Sports | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
