Fixes in-app purchase availability for the Advanced Exploration pack and optional tips.

This update improves scientific data displays and model interaction: • Organic structures: Clear, scalable textbook-style diagrams support panning and selecting atoms and bonds, with molecular formulas, CAS numbers and data sources. • Spectra: NIST-based visible-range neutral-atom spectra support zooming, line selection, wavelength and intensity readouts, a rainbow wavelength scale and quick range selection. • Nuclear models: Improved spherical layouts and proton/neutron distribution, with default isotopes, nucleon counts and color legends. • Magnetic diagrams: Added external-field controls and direction, net magnetization, temperature, material-state information and reference notes. • Interface: Simplified settings and reorganized feature access, with improved full-screen model displays and layouts for different screen sizes. • Data notes: Missing data and the scope of illustrative models are clearly identified for easier learning and reference.

Version 2.0.0 brings a major update, making it easier to explore the elements and learn chemistry. • Refreshed interface: Redesigned home screen, navigation and element details make browsing, searching and reading easier. • 3D views of all 118 elements: Rotate and zoom in on element models. Some elements are represented by experimental equipment or other illustrative objects. • A richer browsing experience: Improved ways to explore element uses, specimens, property trends, compounds and the solubility table. • Core learning and advanced exploration: Basic information on all 118 elements and common chemistry tools are available at no additional cost. Try sample advanced models and choose a one-time purchase to unlock more content. • Existing customers: If you previously paid for the app, you retain access to advanced content without purchasing it again. • iPhone Duo: Layouts adapt to folded and unfolded screens. • More languages: Explore the elements using more interface languages.
