Ballistics and holds, built for the field

Drop Solver helps you work through units, projectile data, and rifle setup to produce drop solutions, wind holds, and a shot log — in a fast, mobile-friendly web app.

Launch Drop Solver Hosted at app.dropsolver.com

What you can do

  • End-to-end solution Configure units, projectile, and platform, then read clear results tuned to your inputs.
  • Shot log Record shots and refer back when conditions change.
  • Range voice Use voice-oriented flow when you are hands-busy downrange.

How we’re different

Ballistics tools span everything from dense desktop suites to narrow calculators. Drop Solver aims for a different balance: a focused, modern web app that respects your time on the firing line.

  • Web-first, not a store receipt Use it in the browser on the devices you already carry—no separate paid app tiers or platform lock-in just to open core features.
  • Workflow, not bloat Built around the path shooters actually follow: confirm units and inputs, see holds and solutions, log shots, and use voice when your hands are full—without unrelated products bundled into the same subscription.
  • Get started fast No account required to use the app. We’re optimizing for clarity and speed, not for upsells at every tap.

Free for everyone—supported by the community

For now, everything in Drop Solver is free to use: the same experience across the board, with no paywalled modes or “pro-only” ballistics features. That can change in the future as costs and scope evolve, but today the goal is simple: get capable tools in more hands.

Hosting and ongoing development are paid for by people who choose to chip in. If Drop Solver saves you range time or helps you shoot more confidently, consider joining them.
