PricePerUnit: Compare Prices

PricePerUnit is built for the moment you're standing in a store aisle with a basket in one hand, trying to figure out which option is actually cheaper.

"2L bottle vs. four 500ml bottles." "Big bag vs. small packs." Just enter the price and quantity for each item, and PricePerUnit instantly shows you which one is the better deal.

Features:

• Enter price and quantity for two items; unit price updates live (per 100g, per 100ml, or per unit)
• The better deal is highlighted in green, with the exact savings shown
• Supports weight (g/kg), volume (ml/L), and count (each/pack) — mismatched units are flagged as "not comparable" to avoid misleading comparisons
• Results update instantly as you type, no button needed
• Auto-focus moves from price to quantity to minimize taps
• Save up to 50 comparisons to history (configurable to 20/50/100)
• Currency follows your locale automatically, or choose manually (USD, JPY, EUR, GBP, CAD, AUD, CNY, KRW)

Great for:

• Shoppers who want to catch the better deal every time
• Anyone torn between bulk and small packs
• Getting a faster, more accurate answer than mental math

Comparison data stays on your device.
