Callie 2.0 Is Coming Soon to iOS and Android
Callie 2.0 has been submitted for iOS and Android, and this is our first major update to the app. Callie started as a simple idea: make everyday math cleaner, calmer, and easier to handle. Today, more than 2,000 people are using Callie, and that growing support has shaped this update in a big way.
Version 2.0 turns Callie into a more polished all-in-one calculator app for daily life. The new design is cleaner, the workspace is more intuitive, and moving between tools feels smoother across iPhone, iPad, Android phones, and Android tablets.
A Cleaner Calculator and Utility Workspace
Callie 2.0 includes Basic and Scientific calculator modes, making it useful for quick arithmetic, memory-key calculations, trigonometry, logs, exponents, roots, constants, and everyday number work. The updated interface uses a dark glass design built to stay readable, focused, and easy on the eyes.
New Currency Converter with Daily Rate Updates
One of the biggest additions is a new currency converter. Callie now supports 169 currencies using fresh daily Frankfurter exchange-rate data, common currency shortcuts, and local caching after the first update. It is built for quick travel math, international comparisons, and everyday currency conversion without clutter.
Money, Conversion, and Date Tools in One App
Callie 2.0 also includes practical tools for tips, bill splitting, sales tax, discounts, unit price comparison, fuel cost estimates, loan payment estimates, unit conversion, percentage math, date calculations, and age differences.
Now Supporting 32 Languages
International support has been one of the most meaningful parts of Callie’s growth. That is why Callie 2.0 expands support to 32 languages, helping more people use the app in a way that feels natural to them.
Callie 2.0 is waiting on store approvals now and should begin rolling out soon.
