Chronograph Log was developed to record your bullet velocities, from your Chronograph, onto your iOS device. No more writing everything down on a pieces of paper to be lost in your range bag. When your friends ask about the loads you are using, you can pull out Chronograph Log and give them accurate info instead of guessing. Send them an email or message on the spot. Share your favorite loads via eMail, Facebook and more. Chronograph Log was primarily developed for USPSA IPSC and IDPA, where Minor and Major Power Factors are very important. It will color code those entries based on their velocities. Note that the Power Factors can be ignored if you are tracking rifle loads or don’t care about Power Factors. Note: This application is not a chronograph. You will need to enter readings from your chronograph into the Chronograph Log app. • Define: Bullets, Guns and Powder in the database. • Record velocities for each round from your chronograph. • Automatically calculate Average, Min and Max velocities. • Color coding to show each velocity’s Power Factor. • Export full tables to Mail. • Export favorite loads to Messages, Mail, Twitter or Facebook. • Backup / Restore to Dropbox. • Bluetooth integration with Competition Electronics "ProChrono Digital" using their "Digital Link" module.

FieldSolve is a fast, accurate ballistic calculator built for long range shooters, hunters, and precision rifle competitors who need a firing solution they can trust on the first shot. Enter your rifle, load, and conditions and FieldSolve solves the full trajectory — bullet drop, windage, and the exact hold or dial in MOA or mils. BALLISTIC SOLVER A precision ballistic engine that accounts for muzzle velocity, ballistic coefficient (G1/G7), zero range, sight height, shooting angle, spin drift, aerodynamic jump, and Coriolis. Get your holdover and windage instantly, as a dialed solution or a reticle hold. BUILT FOR THE FIELD Save unlimited rifle and load profiles. Build range cards and DOPE charts for every distance. A clean heads-up display gives you the numbers you need at a glance, even on the clock. LIVE ENVIRONMENTAL DATA Wind, temperature, pressure, humidity, and density altitude all change your solution. Enter them by hand, or connect a weather meter to pull live atmospherics straight into your solve. Connect an anti-cant level to read your rifle's true cant, and import muzzle velocity directly from your chronograph so your data is real, not estimated. RECORD YOURSELF SHOOTING FieldSolve records video of your shot with a live data overlay — your solution, wind, cant, and velocity burned right onto the clip. Review your form, confirm your DOPE, and share your best shots. FEATURES - Advanced ballistic solver with G1 and G7 drag models - Bullet drop, windage, and lead in MOA, mils, or clicks - Spin drift, aerodynamic jump, and Coriolis - Unlimited rifle and load profiles - Range cards and DOPE charts - Angle (cosine) and cant correction - Metric and imperial units - Live weather, level, and chronograph integration - Video recording with data overlay FieldSolve is a free ballistic calculator. Whether you shoot PRS, NRL, F-class, or hunt at distance, it gives you a firing solution you can rely on. Always follow safe shooting practices and know your target and what lies beyond it. Ballistic solutions are calculated estimates; confirm your come-ups on paper before relying on them in the field.

Verdict
The clearest difference is price: FieldSolve at Free against Chronograph Log's $3.99. FieldSolve also leads on update cadence (every 4 days vs every 10 months). Chronograph Log's advantage is iOS requirement (12.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
