BinHex puts the calculators you actually use in one fast, private app.
CALCULATOR
• The whole expression stays on screen, so you can check what you typed.
• Exact decimals: 0.1 + 0.2 = 0.3. Press "=" again to repeat the last operation.
• Scientific functions that hide behind f(x) when you don't need them.
PROGRAMMER
• Type in HEX, DEC, OCT, BIN or ASCII and see every base at once.
• AND, OR, XOR, NOT, shifts and rotations, with C precedence and parentheses.
• 8, 16, 32 and 64-bit words, signed or unsigned, with overflow warnings. Tap any bit to flip it.
• Text ↔ bytes: UTF-8, hex, binary, decimal and Base64.
UNITS & CURRENCY
• Currency converter with daily rates for 160 currencies; keeps working offline with the last rates.
• 12 unit categories, completely offline.
• Ohm’s law: enter any two of volts, amps, ohms or watts (with prefixes like 4.7k) and get the rest.
• kVA, kW, amps and HP for DC, single phase and three phase.
SHOPPING
• Tip: pick a percentage and split it, with no rounding.
• Discount: price, % off, quantity and sales tax — see exactly what you pay.
• Cart: scan or type each price while you shop and watch the total with tax.
• Sales tax for your area with one tap (approximate; you can correct it and BinHex remembers it).
MODEL MY PAY (optional, turn it on in Settings)
• Hourly or salary, overtime at 1.5× and 2×, and an estimate of your take-home pay with 2026 federal, Social Security, Medicare and California taxes.
• Calibrate it with your paystub or W-2 so it matches your real checks.
• Protected with Face ID. It stays on your phone.
HISTORY & CAMERA
• Everything you calculate is saved on your phone. Tap an entry to pick it back up.
• Point the camera at a number, a price or a receipt total and BinHex reads it (iPhone XS or newer).
No ads. No account. Your data stays on your phone.
• New icon: a lighter calculator that's easier to spot on your home screen.
• Higher contrast colors across the app.
• Model my pay: new "Overtime: what do you keep?" — see how much of each extra hour you take home and where your tax bracket changes.
• Model my pay: Social Security and Medicare per paycheck now match real paystubs for high earners.
• Units → Data: new transfer rate converter (Gbps ↔ GB/s) with a bits vs. bytes explanation.
• Shopping opens on the Cart, and the trash button empties it (after asking).
• Programmer fits on one screen, and a cleaner tab bar.
