⭐ FAVOURITES — YOUR PERSONAL CONVERSION DASHBOARD

Save any conversion pair as a favourite for instant access — and it's right there every time you open the app. Tap, type, done.

- Each favourite is a live conversion card — type and see results in real time
- Swap source and target units with one tap

📱 NEW: HOME-SCREEN WIDGET

Your favourite conversions right on your home screen — no need to open the app. Glance to see each pair and its current value.

- Resize it: small for a couple of pairs, large for a dashboard of up to 30
- Tap any tile to jump straight into that conversion in the app

🧩 NEW: COMBO CONVERSIONS

Real-world numbers are often ratios. Combo lets you build both sides — any unit over any other unit — and converts the whole thing at once.

- Fuel economy: miles per gallon → km per litre
- Mass flow: kilograms per minute → pounds per hour
- Data transfer: megabytes per second → gigabytes per hour

Tap a preset to start, or build your own from any two compatible units. You can flip the target to its inverse, and any combo can be saved as a favourite so it shows on Home.

🛠️ BUILT-IN TOOLS

- World Time — current time in multiple cities at once
- Age Calculator — exact age from date of birth
- Date Difference — days, weeks, months and years between two dates
- BMI Calculator — body mass index from kg and cm

⌨️ CUSTOM NUMERIC KEYBOARD

Purpose-built keyboard with operators (+, −, ×, ÷) so you can type expressions like "5.5 × 2" and convert the result directly. Copied a number from a message, spreadsheet or lab report? A dedicated paste button drops it into any field — no switching keyboards, no selecting text.

🎨 LIGHT & DARK THEMES

Pick Light, Dark or follow your system setting. English and Spanish.
