What's New in NearLight

1.7.0

August 10, 2026

NEW IN 1.7.0 • Start Guide: an interactive tour of all five views, for newcomers and pros (Mac & iPad) • NearLight now speaks French • Revised Optics: Newtonians show coma, the achromat refractors wear their violet fringe, bright planets dazzle the eye — and Mercury's day side finally shines • Calibrated under a real night sky: object brightness per Bortle class, the eyepiece background now carries the light-pollution glow, and the field stop is pitch black • Red light mode in both observing views and the app remembers red light across restarts • Audio mute is beeing saved across restarts • Smoother sky transitions, the view reaches the zenith, and the target readout no longer flickers between close objects • New filter sounds, a Jeep at the Rocky Mountains site, twilight colors on the Moon's shadow side • Easier on the battery: GPS takes a single fix and the renderer rests when you do FIXED • Startup crash on older iPads (4 GB devices)

User reviews

Very sophisticated and helpful support from the developer

Issue I had with the app running on an old iPad were quickly resolved. It was quite fun using the telescope mode which does a good job of showing how objects look through eyepieces. Made me want to go out and use my real scope!

Response from developer

At least thanks for telling me. Already have a hotfix in place in 1.7.0 for old devices. Awaiting approval, out shortly. Sorry for this.

Initial Impressions

I liked the tool but thought the overall description and instructions could be developed further. Include some examples of how it can be used. Otherwise I like the graphics, sound etc. I did think it would be fun to be able to zoom in on solar system planets to enhance their available detail, eg there’s a lot of detail that could be added to a zoomed-in Mars

Response from developer

Version 1.7 will introduce a Getting Started Guide that explains the UI and features in more detail. The textures can still be improved, at least on Mac. Noted. Thank you.

This app is good but one thing…

This app is good, but needs updates more often, and it needs to have a universe map. A Universe Map but not a night sky.

Response from developer

Thank you! I‘ll keep updating as frequent as possible. Promise. Universe is the last big step which is on the roadmap. But incredibly hard to design. But I’m on it.

Great

A great app that isn't limited to the solar system. It's great fun just letting your imagination run wild.

My Google Earth for Space

I'm not an astronomer, but I just love "playing" with this app, and it never ceases to amaze me because I simply can't imagine these vast scales. The app runs very smoothly and stably. Most of all, I love the interactive 3D view of the Milky Way and the black hole.

FAQ

What is NearLight?

NearLight is a 3D space simulator that allows you to explore nearby star systems, visualize interstellar distances, and calculate travel times using both classic and relativistic physics. It's designed for astronomy fans, sci-fi lovers, and physics enthusiasts.

What kind of physics does NearLight use?

NearLight utilizes both classic physics and relativistic physics, including concepts like time dilation and the Lorentz factor. You can see how space travel changes when relativity is considered, especially near massive objects like black holes.
