The RCBS Reloading App is perfect for any reloader! Not only can you operate the new ChargeMaster Link, Chargemaster Supreme and MatchMaster powder dispensers; our comprehensive Load Log gives any handloader the ability to save, store and even export their favorite load data. The Load log gives the handloader a convenient location to store your firearm profiles and critical information about each firearm including round count, barrel length, rifle twist and even scope height! The Load section allows the user to upload an image of their favorite group, and put in all critical information about the loads they are using! All the new RCBS powder dispensers are now Bluetooth enabled to provide direct control of your ChargeMaster Link, Supreme and MatchMaster from the intuitive app so you can control every handloading session.

The app allows you to easily calibrate the scale and prepare your dispenser for your handloading session using the on-screen walkthrough.

SinkerCalc

Stop guessing what sinker to tie on. SinkerCalc calculates the right weight based on your depth, current speed, wind, rig type, and line — updated in real time as tides shift. Every angler knows the frustration: you were holding bottom an hour ago, but now your bait is drifting. The tide changed, and your 1 oz sinker is no longer enough. SinkerCalc solves this by combining live tidal current data with your setup. HOW IT WORKS 1. Set your rod profile (casting weight limit + line type) and fishing depth. 2. SinkerCalc fetches current tide and wind conditions from NOAA and Open-Meteo. 3. Get an instant sinker weight recommendation in oz, plus the right sinker shape for your bottom type. It takes 30 seconds to set up. No account required. SINKER WEIGHT CALCULATOR Enter depth, select bottom type (sand, rock, mud, mixed), and choose your rig (bottom, Carolina, drop shot, fish finder, knocker, or float). The app factors in current speed, wind, rig drag, and line diameter to give you one clear number. SINKER SHAPE GUIDE Not just weight — SinkerCalc recommends the right shape. Pyramid for sandy bottoms in strong current. Bank sinkers for rocky structure. Egg for drifting presentations. LIVE CONDITIONS See current tide phase, tidal current speed, and wind at a glance. Know when conditions are changing before your bait starts drifting. Upgrade to Pro for deeper insights: - Hourly sinker weight timeline — see how weight changes throughout the day - Unlimited saved spots and rod profiles - 7-day tide forecast with best and worst fishing windows - Multi-spot comparison - Species-based weight adjustments - Tide change notifications PRIVACY FIRST All data is stored locally on your device. No account, no tracking. Location is used only to find your nearest tide station and fetch local wind data — coordinates are never sent to our servers. SinkerCalc is a reference calculator that estimates sinker weight based on depth, tidal current, wind, rig type, and line type. Results are general guidelines — actual weight needed depends on local conditions, bait, and technique. This app does not guarantee fishing results.
