Iron Raven Plate Calc is a barbell plate calculator for the gym floor. Enter a target weight (or build a load plate by plate), and the app works out what to put on each side using your bar, collars and the plates you actually have.

Where is my data stored?
Only on your device. Your gym profiles, inventory and saved bars aren't uploaded, and we can't see or recover them. If you replace your phone, you'll need to set up gyms again unless you restore from an iPhone backup.
What is a gym profile?
Each profile is a full setup for one location: which plates you have, your bars, competition vs gym mode, and the calculator state for that gym. Switch profiles from the calculator menu or Settings > Gym profiles. The free version includes up to two profiles; Pro unlocks unlimited profiles.
How do the free loads work?
You can run 10 successful plate calculations for free — meaning the app found a valid load with your current setup. Repeating the same load doesn't use another free slot. After 10, you'll need Pro for unlimited calculations. Pro doesn't remove features from the calculator itself; it removes the load limit (and the profile limit).
I bought Pro. How do I get it back?
Go to Settings > Restore purchases, signed in with the same Apple ID you bought with. If Family Sharing is on, family members may get it too.
How do I get a refund?
Purchases are handled by Apple. Request a refund at reportaproblem.apple.com.
Kg and lb plates
Choose Settings > Units for the target and totals. Choose kg or lb bumpers under the Plates tab (per gym profile). Competition mode always uses kilo plates, bar and collars, even if you usually train in pounds.
The load is short of my target
The app only uses plates you've said you own. Raise inventory counts on the Plates tab, or lower the target. Shortfall is shown when your inventory can't reach the weight.
Wrong bar or plates after switching gym
Make sure the correct gym profile is active (check the name in the calculator menu). Each profile keeps its own inventory and saved bars.
Pinch to zoom on the bar
Use two fingers on the bar illustration in the calculator. Tap the bar in target mode to switch to stack editing; tap individual plates in stack mode to remove them.
