## What is Jabr Pro?

Jabr Pro is an all-in-one scientific and engineering calculator app, built to replace multiple scattered math and engineering apps with a single, elegant tool. It pairs a clean, intuitive interface with a powerful calculation engine designed for students, engineers, and math enthusiasts alike.

The app includes a full-featured scientific and engineering calculator (with a programmer mode for number systems), a step-by-step equation solver, and an interactive 2D and 3D graphing engine. It also offers a complete geometry toolkit (areas, perimeters, triangle solving, coordinate geometry, vectors), a probability calculator, a comprehensive unit converter, and a text-to-Unicode math symbol converter.

The app keeps a calculation history, supports customizable themes, and is available in eight languages including full right-to-left Arabic support — running on iPhone, iPad, and Mac. Pricing is a 3-day free trial followed by a one-time purchase for lifetime access, with no recurring subscription.

We streamlined the upgrade process for a clearer Lifetime Premium unlock, improved the "Services Hub" interface for easier navigation, and enhanced overall app launch speed and performance.

### 2.0.0 — 2026-07-12

تم إجراء تحديثات جوهرية لفصل نظام الشراء الدائم عن الفترة التجريبية تماماً لضمان عدم تداخلهما ضمن الخدمات الاحترافية والتي تشمل حاسبة الهندسة وحلّال المعادلات ومحول الوحدات ومحول رموز الرياضيات والرسوم البيانية التفاعلية ثنائية وثلاثية الأبعاد. شملت التعديلات إضافة زر لاستعادة المشتريات في شاشة الترحيب وتفعيل التجربة التلقائية عند الدخول ليتسنى للمستخدمين تجربة الميزات المتقدمة مثل مولد الثيم السحري والسجل الذكي والقدرة على العمل بدون إنترنت. كما تم تحديث واجهة مركز الخدمات لعرض ملاحظات ديناميكية أسفل كل أداة توضح حالة الصلاحية وتنبيهات الإغلاق، وتحديث الشاشة الرئيسية لعرض تاج ذهبي للمشتركين الدائمين أو عداد زمني للمستخدمين في فترة التجربة.

Major updates were implemented to completely separate the lifetime premium system from the free trial period across professional services, which include the Geometry Calculator, Equation Solver, Unit Converter, UnicodeMath Converter, and interactive 2D and 3D Graphing engines. The modifications include adding a restore purchases button on the welcome screen and automatically triggering the trial upon entry, allowing users to fully experience advanced features like the Magic Theme generator, Smart History, and offline capabilities. Furthermore, the Services Hub was upgraded with dynamic status notes under each tool to indicate current access permissions and lock warnings, while the main calculator display was updated to show either a premium crown for lifetime users or a countdown timer for users currently in their trial period.
