Minor bug fixes and enhancements following the prior major release of V2.0 that includes rich notifications, a new fault database and many operational and performance improvements.

What's New in Epicenter This update introduces earthquake notifications for the first time and Epicenter+, a new way to monitor places and regions that matter to you. • Earthquake notifications for worldwide and location-based significant events • Epicenter+ with Watched Locations, Watched Regions, and expanded earthquake reports • Notification history so you can revisit recent earthquake alerts • Monthly earthquake summaries to highlight recent global activity and confirm notifications are working • Updated fault and plate boundary datasets • Epicenter+ New annotations and descriptions for faults and plate boundaries • Custom Epicenter notification tones and haptics • Performance, reliability, and data handling improvements Existing free features remain free. Epicenter remains ad-free.

Further stability improvements. For those affected, thank you for your patience.

Additional stability fixes and improvements.

Additional performance and reliability updates resulting in faster start-up and earthquake list interactions.

Completed important architectural upgrades in preparation for new features to be released sometime this summer. For now, user should continue to see improved performance and reliability throughout the app.

A significant improvement in performance and reliability of earthquake data fetching, with clearer download status messaging during refresh. Manual refresh is now available via a pull-down on the List View or in Settings. Earthquakes sourced from European seismic networks (EMSC) now show the contributing network for added attribution. Numerous small defects are addressed too.

This update adds powerful new ways to explore global earthquake activity, along with major improvements to performance and usability. • New Earthquake List View — Browse the full global catalog of recent earthquakes with sorting and filtering by time, magnitude, distance, and more • Redesigned event details — Clearer, more informative earthquake data with improved formatting and direct links to full USGS event pages • Smarter navigation — Tap any event to fly to its location on the globe with smoother, more predictable animations • Faster and more responsive — Improved data loading and smoother interaction when exploring large datasets • Improved layout and controls — Cleaner interface and better organization across iPhone and iPad • More reliable connectivity — Improved handling of network changes with clear offline indicators • Additional refinements and fixes for performance, stability, and visual polish

This update brings a major visual and architectural refresh to Epicenter: • Modern interface overhaul — Updated with a clean SwiftUI design featuring improved readability, Dynamic Type support, and refined controls for the iPhone and iPad • Enhanced dark mode — The interface now adapts seamlessly to light and dark appearances • Improved iPad experience — A more stable layout with persistent controls and better use of screen space • Faster, more reliable data loading — Improved earthquake data fetching with clearer status feedback • Updated 30-day global dataset — More robust data retrieval with improved fallback handling • Performance and stability improvements across the app

Converting the user interface to SwiftUI and the latest Apple User Interface guidelines. This release lays phase 1 foundational work with few noticeable user interface changes. Further phases (3-4) of work will continue to be released incrementally until the conversion is complete.

A maintenance update improving performance and stability, along with bug fixes.

Maintenance Release for iOS26

1. Fixes intermittent crashing on startup while checking for Internet connectivity 2. Addresses white labeling when it should be black and therefore appears "missing".

Bug Fix: The earthquake date was shortened or missing from its annotation view on some devices. Thanks to a user from Oregon, CA for alerting us to the issue!

Fixed a sudden loss of map tiles - Sorry for the inconvenience! They are back.

Maintenance update for iOS18

Maintenance update iOS17

Maintenance release for iOS16 and iPadOS16

Maintenance Release

- Upgraded to v3.2 of the geospatial WhirlyGlobe-Maply framework, the backbone of Epicenter. This version is based on Apple's Metal rendering engine and so you will see differences and improvements in the way the terrain data is rendered from the prior version. - Bug fixes

Beginning a process to update to the latest software versions, etc. More to come! Thank you for using Epicenter.

The Apple Watch gets some deserved love. One broken complication was fixed and a few more new complications were added. We threw in some bug fixes and maintenance to support iOS13 as well!

Bathymetry, it's here!

- Throttled back the map tile update priority in an attempt to partially alleviate the "small label text" issue on the maps by slowing the loading process - Updated the plate boundary data to the latest provided by the USGS - New, added quaternary and historic USGS fault data (<15,000 years) for the western United States - Small (but important) visual and functional improvements added here and there - And a bug or two squashed! Enjoy!

Fairly Big Update For The iPhone! - Improved scroller that is used to explore earthquake distributions in time - It's now easier to access settings and see the results of your changes at the same time - Connectivity and data download performance and messaging are improved - Plus lots of little bug fixes and small improvements - We are working on other improvements in preparation for iOS13, stay tuned
