ShotAnalyzerX vs Strelok Internal Ballistics

ShotAnalyzerX is a target photo and shot group analysis app for iPhone and iPad, designed for precision rifle shooters, handloaders, PRS, Benchrest and F-Class competitors, and hunters. Take a target photo with your iPhone or import one from your photo library. Calibrate the image and mark the bullet holes to analyze your shooting results. NEW IN RECENT UPDATES: • Customizable Target Exports: Choose between clean photos without stats, single-group overlays, or full multi-group summary cards. • Smart Parameter Cards: Keep shared session context visible while minimizing screen footprint. • Polish Localization: Fully translated interface for our Polish shooting community. • Smooth iOS 27 Zooming: Refined touch gestures and scaling accuracy during calibration. • Mean Radius: Measure the average distance of shots from the group’s mean point of impact. • Modern Translucent UI: Maximum visible target area with intuitive touch overlay controls. • Tactile Haptics: Precise vibration feedback when placing bullet impacts and aiming points. CORE FEATURES: • Group Measurements: Mark the centers of bullet holes to calculate the diameter of the smallest circle enclosing them in MOA, MIL or mm, plus Mean Radius. Add a Point of Aim to measure the mean Point of Impact offset from it. • Multiple Groups per Target: Analyze and color-code multiple distinct shot groups on a single target — perfect for powder charge ladder tests and bullet seating depth experiments. • Composite Group Analysis (Premium): Overlay groups from multiple targets to evaluate dispersion using a larger sample of shots. A limited number of free trials is included. • Ammunition Notes: Save caliber, shooting distance and date. Use the project description to record bullet weight, powder charge, primer type and measured muzzle velocity. • Scale Calibration: Mark two points on the target and enter the distance between them in millimeters or inches. • Project Search and Sorting: Search by name, description or caliber. Sort projects by name, last modification or best group size. • High-Resolution Export: Generate professional target summary images and reports to share with your coach, shooting partners, or shooting logs. • iCloud Synchronization: Sync projects and target photos between devices using the same iCloud account when iCloud is available. FREE AND PREMIUM: • Free Version: Single-group analysis, calibration and core calculations. Includes 5 group-combining trials and 10 free additions of another group to a target. • Premium: Add unlimited groups to a target and combine groups from multiple targets without trial limits.

Strelok Internal Ballistics is the mobile Quick Load: an interior-ballistics workbench for precision handloaders. It's the load-development companion to Strelok Pro — Pro solves the bullet in flight, this app helps you build the cartridge, and predicts what that cartridge will actually do before you ever pull the trigger. PREDICT YOUR LOAD — ON DEVICE - Pick a cartridge, powder and bullet, and the engine predicts muzzle velocity, peak chamber pressure and case fill across the whole charge range. - A live chart plots velocity and pressure against the SAAMI/CIP maximum, with a clear over-pressure warning zone. - The engine is fit to 34,000+ published loads and runs entirely on your device — no signal needed at the bench. CALIBRATE IT TO YOUR RIFLE - Enter the velocities you actually chronographed and the engine tunes itself to your barrel and powder lot, so every prediction is personalized — not a generic table. LOAD LAB — YOUR DATA, SMARTER - Find your velocity node (the flat spot / OCW window) and your lowest-spread charge automatically. - Track powder temperature sensitivity (fps/degF) and barrel round-count and life. - The more you log, the sharper your load development gets. A REFERENCE THAT WORKS OFFLINE - 34,000+ published loads across 519 cartridges and 100+ powders, normalized from Hodgdon, Vihtavuori, Alliant and Norma data. - Browse by cartridge, then filter by bullet weight and powder — start/max charge, velocity, pressure and COAL, with SAAMI/CIP context. The whole catalog lives on your device. A SMARTER LOGBOOK - Record loads with full component detail and chronograph strings. - Automatic statistics: average velocity, standard deviation (SD) and extreme spread (ES). - Track rifle profiles and your powder, primer, brass and bullet inventory. PART OF THE STRELOK ECOSYSTEM - One Strelok account works here and in Strelok Pro. - Develop a load here, then send it to Strelok Pro with its measured muzzle velocity (Rifles > Import from Reload on the Pro side). - Strelok Cloud keeps your logbook, rifles and developed loads in sync across devices. BUILT FOR SAFETY Predictions are a development aid, not published load data. The app always shows the start charge, clamps and warns against SAAMI/CIP maximum, and reminds you to start low and work up while watching for pressure signs. Always cross-check against your component manufacturer's current data. This app is not a maximum-charge authority — you are responsible for safe reloading practice. FREE & PRO Free: browse the full catalog, keep your logbook, and run the prediction engine. Pro adds chrono calibration and Load Lab analytics — monthly or yearly subscription (7-day free trial), or a one-time Lifetime purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel anytime in your App Store account settings.
