RangeWatch is the ballistic calculator inside LicenseWatch. Set up your firearm, sights and ammo once. Then type the distance and tap where the wind comes from, and it tells you how many clicks to turn your scope, or how many centimetres higher and into the wind to aim.
Made for beginners and experienced shooters
- Beginner mode explains every box in plain words, with help next to each one.
- Ammo presets for popular factory loads fill in bullet weight, speed and ballistic coefficient for you. You can always type your own from the box or the maker's website.
- A wind clock: tap where the wind comes from. Not sure how strong it is? Pick what you see, like leaves moving or dust blowing.
- Metric throughout: metres, centimetres, m/s for bullet speed and km/h for wind.
What it works out
- Clicks for the top (elevation) and side (windage) dials, in MOA or MIL.
- Hold-over and hold-off in centimetres for red dots and open sights.
- The effect of air temperature, air pressure and uphill or downhill angles. Tap Use my location to fill in today's weather.
- G1 and G7 ballistic coefficients.
Handy tools
- Zero helper: fire 3 shots, measure how far off they are, and it tells you which way to turn and how many clicks.
- Range card: a printable table of clicks for every distance.
- True my firearm: match the calculation to where your shots really land.
- Log session: add the outing to your shooting log for your dedicated status.

Frequently asked questions
What is a ballistic calculator?
It works out how far your bullet drops and drifts in the wind at a given distance, so you know how much to adjust your sights or where to aim.
Do I need to know my ballistic coefficient?
No. Pick your ammo from the list of popular factory loads and RangeWatch fills it in. If your ammo isn't listed, the number is usually on the box or the maker's website.
Does RangeWatch work with a red dot or open sights?
Yes. Without a scope it tells you how many centimetres higher and to the side to aim instead of clicks.
How accurate is RangeWatch?
It uses standard ballistic models, but every firearm and batch of ammo is a bit different. Treat the numbers as a starting point and confirm them at the range. True my firearm helps you match it to your real shots.
How much does RangeWatch cost?
It's free during your 14-day trial, then R9.99 for 30 days, R80 a year, or R149 a year with Pro.
