Energy Horizon is a mobile climate simulation built around a dynamic model of Earth's oceans and their interaction with global climate systems. It puts you in control of real-world scenarios, letting you watch how water, temperature, and currents respond to different planetary conditions. The app is aimed at anyone curious about how Earth's systems actually work — from casual explorers to people with a deeper interest in oceanography. The interface blends live data readouts with an interactive world map, giving each session a distinct and evolving feel.

Screens & Views

Inside the Simulation

Energy Horizon models the relationship between Earth's oceans and climate in a way that plays out differently every time. Rather than presenting static information, the app runs live simulations that track water movement, temperature shifts, and global circulation processes as they evolve step by step.

What the Simulation Covers

The core of the app is its Live Ocean Grid, a world map that renders ocean current vectors across labeled regions including the Arctic Halocline, North Atlantic Drift, Indian Monsoon, Gyre Pacific Equatorial Belt, and Antarctic Circumpolar. A live data panel sits alongside the map, displaying mean sea surface temperature in °C, salinity in PSU, and water density in g/cm³. The Time Controller lets you run simulations at speeds from 1× up to 1000×, and individual steps can be played, paused, or undone.

Scenarios and the Stats Lab

The app ships with named scenario kernels such as Baseline Earth — described as stable thermohaline circulation with present-day forcings — and a Glacial Maximum scenario involving cold polar caps and temperature collapse parameters. Each scenario carries its own ΔT and wind multiplier settings. A dedicated Stats Lab screen provides long-form analytics on the active circulation kernel, with structured cards showing MIN, MAX, AVG, and sample counts for surface temperature and salinity readings.

Design and Accessibility

The visual style runs on a deep blue gradient with yellow and gold accents — high contrast throughout, with icons paired to text labels on every metric card. Navigation uses a bottom tab bar with Home, Stats, Simulation, and Settings. The layout holds up well for most users, but the complex ocean current visualization currently lacks alternative text descriptions, which limits usability for screen reader users. Real-time updating values also present challenges for assistive technology, as live content can be difficult to track without properly implemented live regions.

The simulation produces a genuinely different climate pattern each run, which gives it more replay depth than the sparse scenario list might initially suggest.

A Visual Language Worth Noting

The app's icon places a bold golden lightning bolt diagonally across a rendered Earth globe — an image that carries real visual energy. That same deep blue and gold palette runs through every screen, from the swirling background animations on the dashboard to the metallic ring decorative elements framing the data cards. It's a look that feels alive, charged with motion — not unlike the electric atmosphere of a lightning-themed slot game, where blue backdrops, glowing gold symbols, and a sense of dynamic unpredictability define the experience. In Energy Horizon, that unpredictability belongs to the ocean itself.

How It Works

What data metrics does the app track during a simulation?
Energy Horizon monitors mean sea surface temperature (°C), mean salinity (PSU), peak current speed (knots), and ocean water density (g/cm³) in real time. These values are displayed in a live data panel alongside the ocean grid visualization.
Can I control how fast a simulation runs?
Yes, the Time Controller lets you choose from multiple simulation speeds: 1×, 10×, 100×, and 1000×. You can also pause, advance a single step, undo, or play the simulation at any point.
What climate scenarios can I run in the app?
The app offers scenario kernels such as Baseline Earth, which models stable thermohaline circulation with present-day forcings, and Glacial Maximum, which simulates cold polar caps and temperature collapse conditions. Each scenario has its own configurable parameters like temperature delta and wind multiplier.
Can I save my simulation and come back to it later?
Yes, the dashboard includes a Saves section and a Resume Current Run button, so you can pause your work and pick up an ongoing simulation exactly where you left off.
Which ocean regions are shown on the live simulation map?
The live ocean grid visualizes current flow across labeled regions including the Arctic Halocline, North Atlantic Drift, Indian Monsoon, Gyre Pacific Equatorial Belt, and Antarctic Circumpolar. Ocean currents are displayed as directional arrows over a world map.

Ich habe mir Energy Horizon jetzt einige Wochen lang intensiv angeschaut — und ich muss sagen, dass die App mich in einem merkwürdigen Zwiespalt zurücklässt, der sich nicht so leicht auflösen lässt. Auf der einen Seite ist das Konzept wirklich bemerkenswert: eine Echtzeit-Simulation der Ozeane und Klimasysteme, bei der man …

Margot_liest: ohne Kontext bleibt eine Zahl wie 34,73 PSU Salinität für die meisten Nutzer schlicht bedeutungslos

Also ich muss sagen, ich sehe das ein bisschen anders... Klar, der didaktische Aspekt könnte ausgebaut werden, das stimmt schon. Aber für mich persönlich war genau diese offene Simulation das Faszinierende daran 😊 Ich habe einfach verschiedene Szenarien laufen lassen und dabei gemerkt, wie unterschiedlich sich die Strömungsmuster entwickeln — das hatte fast schon etwas Meditatives. Die App erklärt vielleicht nicht alles, aber sie regt zum Nachdenken an... und das finde ich eigentlich wertvoll! Manchmal muss man nicht alles erklärt bekommen, oder?

Stimme Margot_liest zu. Fehlende Erklärungen sind ein echtes Problem. (iPhone 14, iOS 17.4) Stats Lab zeigt Werte, aber kein einziger Tooltip. Kein Hilfetext. Keine Einheit erklärt. Für Einsteiger unbrauchbar.

hm ich bin halt irgendwie neu bei sowas und hab die app letzte woche runtergeladen... ich finde es total schon aber ich versteh halt manchmal nicht was die zahlen bedeuten sollen??? wie zum beispiel diese PSU sache, was ist das uberhaupt?? hab im support nachgefragt aber irgendwie keine antwort bekommen bis jetzt, ist das normal so???
