iPhone

Telly is a tactile unit converter with various themes to choose from: Minimalistic (neumorphic dial input) or Retro (CRT and classic computer with hardware keypad input). Telly is an iPhone unit converter where the interface is the product. Each theme is a full layout, type system, sound design, and input model, not just a color overlay on one screen. New themes will be added over time. Telly Pro unlocks the theme collection, including those added after you buy. THEMES IN THIS VERSION Minimalistic is a neumorphic converter: large from/to readouts and a weighted precision dial. Light, dark, and system appearance are supported, including an optional matching app icon. Retro Computer is a separate environment. Switch between a CRT phosphor display and a classic computer-style workspace. Units load through a floppy-disk flow and values are typed on a hardware-style keypad with click feedback. Motion on the CRT glass stays on the device. HOW YOU ENTER VALUES Input changes with the active theme which includes: - Precision dial for analog increments, with finer control when you need more decimal places - Tap a value to copy or continue from it - Swap source and destination without re-picking units - Category and unit pickers, including military time (24-hour ↔ 12-hour with AM/PM) - Hardware-style keypad and floppy-based unit selection in Retro Computer - Sound and haptics can be turned off independently in Settings. WHAT YOU CAN CONVERT Distance, mass, temperature, volume, duration, energy, speed, frequency, angle, area, power, data, data rate, pressure, fuel economy, military time, and currency (major fiat plus BTC and ETH). Currency uses public rate APIs, is cached on device, and is labeled as approximate and not a live trading quote. WIDGET AND SHORTCUTS A Home Screen widget shows your last conversion. Siri Shortcuts can read that conversion or open Telly. TELLY PRO Telly Pro is a one-time In-App Purchase (not a subscription). It unlocks paid themes available now and themes added later, plus higher library limits. Restore is in Settings, tied to your Apple ID.
