Vitamin Tracker vs Fast Barbell Plate Calculator

An organizer app for managing multiple supplements as stacks (groups). [Stack Management] Group supplements by purpose such as morning, workout, or night. Log all supplements in a stack with a single tap, or check off individual items when needed. [Calendar View] View your intake history on a monthly calendar with color-coded dots for each stack. Tap any date to see detailed records and spot missed days at a glance. [Streaks and Statistics] Stay motivated with a streak counter for consecutive logging days. View completion rates per stack and a GitHub-style activity heatmap for the past year. [Inventory Tracking] Register bottle quantities and the app auto-calculates remaining supply from your logs. Get notified when stock runs low so you never run out. [Cost Tracking] Enter prices per supplement and see total monthly and yearly costs. Break down costs by stack to understand your spending. [Flexible Scheduling] Set schedules for daily, specific weekdays, gym days, or ON/OFF cycles. Reminders notify you at the right time so you never miss a dose. [Data Management] Export and import your data in JSON format for easy backup and restore.

For anyone who loads a barbell and doesn’t want to think about math between sets. Type the weight you want. Barbell Calculator splits it across both sides and shows you the stack on a bar you can pinch and zoom. Quick to read at a glance—especially when the gym’s loud and you’re in a hurry. Free (no ads) Target weight → plate breakdown + bar preview. Pounds or kilograms. Haptics on or off. Uses a normal Olympic-style plate set so you’re not digging through settings before your first set. Pro (one-time, not a subscription) When your gym isn’t “textbook”: Stack mode — Add plates like you’re at the rack; total updates as you go. Your rack — Match the sizes and counts you actually have. Your bar — Not 20/45 kg? Set your empty-bar weight. Tap the bar — Easily remove weights; it recalculates the rest so you’re not starting over. If you just need “what goes on the bar for 275?” the free app has you covered. If you want the app to behave like your gym, Pro is the upgrade.
