Store description excerpt
Five tools that usually mean five apps: a real expression calculator, exact fraction maths, a unit converter, a time tracker and notes — in one place, all working offline. Nothing you type is collected, uploaded or tracked. No account, no sign-in. CALCULATOR Type the whole sum the way you'd write it, brackets and all, and watch the answer update before you press equals. 2(3+4) works. 200+10% gives 220. Swipe the display to delete. Scientific keys when you need them: sin, cos and tan in degrees or radians, natural and base-10 logs, square and cube roots, factorials, permutations and combinations, π and e, memory keys and a running Ans. Every calculation goes into history, ready to reuse or edit. FRACTIONS A fraction calculator that stays exact. One third plus one sixth is exactly one half — not 0.4999999. Type mixed numbers, improper fractions or decimals. Enter 0.375 and it comes back as 3/8, precisely. Every answer shows four ways at once: fraction, mixed number, decimal and percentage. CONVERT 107 units across 14 categories: length, weight, temperature, volume, area, speed, time, data, energy, power, pressure, angle, fuel economy and frequency. Centimetres to inches, kilograms to pounds, Celsius to Fahrenheit, litres to gallons — and every other unit in the category at the same time, so you never convert twice. US cups and metric cups are listed separately, because they are not the same measurement. TIME One tap starts a timer, one tap stops it. Set a daily goal and watch the ring fill. Totals for today and this week, a seven-day chart, and a full session log grouped by day. Log time you spent away from your phone by hand. Give every project its own colour and icon. NOTES Search, pin and colour your notes. Everything saves as you type. Send any result from any other tab straight into a note — a conversion, an exact fraction, a week of tracked time. BUILT TO FIT YOU Light, dark or automatic. Six accent colours. Haptics you can switch off. Choose how many decimal places results show. PRIVACY Numera works entirely on your iPhone. There are no ads, no subscriptions, no analytics and no accounts. Your calculations, notes and time logs never leave your device.
