WALT Calculator is a toolbox containing many useful weather, location, and target related computations. WALT: Weather, Altitude, Lat/Long, Target Features: 1. Density Altitude Calculator Great for pilots, shooters, or weather enthusiasts, the WALT's density altitude calculator can provide a useful meteorological metric for comparing performance in differing weather conditions. For devices with a pressure sensor (iPhone 6 and later), DA can be automatically calculated from the device's own pressure sensor. 2. Field Elevation Calculator Know the ambient/station pressure and the alimeter setting/barometric pressure? Calculate your elevation above mean sea level with this calculator. Know your elevation but not your ambient pressure? With the field elevation calculator, you can calculate any of these three metrics! 3. Geographic Coordinates Converter Convert a geographic location from degrees, minutes, and seconds into decimal degrees, decimal minutes, or UTM. 4. Geographic Distance Calculator Find the distance between two points on the globe, given a set of geographic coordinates. 5. Target Calculator Designed primarily for shooting sports, the target calculator can compute distance to target, given target size and angle. Or target size, given target distance and size. This is a great complement to a mildot or MOA reticle optic.
Ballistica

Ballistica is a ballistic calculator for long-range shooters who want clear corrections and can see the data behind them. Pick a rifle and a load, enter the line-of-sight range, angle, wind, and conditions, and Ballistica gives you elevation and windage: the direction, the angle, the linear drop or drift, and turret clicks when your scope's click value is set. THE SOLVER • 3D point-mass trajectory model • G1, G5, G7, and G8 drag models, plus custom drag curves • Optional spin drift, Coriolis, and aerodynamic jump • Line-of-sight range and inclined shots • Temperature, pressure, humidity, and altitude, or live conditions from Apple Weather • Station pressure from your iPhone's barometer • Separate conditions for the day you zeroed • Two-stage truing for muzzle velocity and drop scale, with powder temperature taken into account • Warnings for transonic and subsonic flight and for ranges beyond what the model has been checked against CLEAR RESULTS • Elevation and windage in MOA or MRAD, with dial and hold shown side by side • Turret clicks in your scope's own unit, and a warning when a correction exceeds your turret's travel • Linear drop and drift, remaining velocity, Mach, energy, and time of flight • The drag model, ballistic coefficient, velocity source, zero, and truing status are always visible • A clear marker when changed inputs make a solution out of date IN THE FIELD • Stage planner: every target on a stage, in shot order, with a printable wrist card (Pro) • Hit probability for a chosen target size, and which error is costing you the most (Pro) • Measure shot angle and rifle cant with your iPhone • Reticle view with generic MOA and MRAD reticles, including trees with wind dots and second-focal-plane scaling • Optional energy and velocity guidelines for hunting • Trajectory graph for drop, velocity, and energy • Range cards on A4 or Letter, exported as PDF • Mover lead and mil ranging • Widgets, a Lock Screen Live Activity (Pro), and Siri and Shortcuts: ask Siri for your elevation and wind at a given range RIFLES AND LOADS • Rifle and scope profiles with multiple zeros • Custom loads and a built-in bullet library • Import velocity strings from Garmin Xero and LabRadar CSV files, set muzzle velocity from the average, and estimate temperature sensitivity • Share a rifle, load, or saved setup as a file or a QR code • Saved setups for the combinations you use most RANGE SESSIONS • Log observed impacts against the prediction • Group size, mean radius, and average vertical and horizontal offsets • Notes, location, and an optional target photo • Filter by date and rifle, export a session as CSV, or share a summary image YOUR SETTINGS • Metric, Imperial, or mixed units • Daylight, Field Dark, Sunlight, and Low-Light Red themes, or follow the system • Large text, VoiceOver, and Reduce Motion support • iCloud sync and full backups Ballistica Pro is a one-time purchase. There is no subscription and no account.

Verdict
The clearest difference is in-app purchases: WALT Calculator at none against Ballistica's 1. WALT Calculator also leads on iOS requirement (8.0 vs 17.0). Ballistica's advantage is update cadence (every 2 weeks vs every 3 months). On price, ads and device support there is nothing between them.
