What's New in Sector

2.5

May 18, 2026

Sector is alive! Thank you for your support and interest in this app. NEW: Empires - optionally display generated empire boundaries and areas. Now no world needs stand alone. FIXED: This release fixes a long standing crash when regenerating trade routes. Thank you for your patience, I think we got there in the end! Temperature and population description fixed a bug where every where could be cold and empty. UPDATED: The app has also been refreshed and updated to look better on the latest system versions.

Works after iOS/iPad reboot.

IPad 11 / iOS 16.1 Try to create random subsector: app crashes.

After rebooting iPad, auto generate subsecotrs and trade routes work.

Whew!

Love cool mapping tools like this.

PS: their rpg game term generator tool, it also rocks!

Amazing app for Traveller and similar RPGs

Love this app! It’s an amazing way to rapidly generate a detailed sector map. And it’s editable!! The only thing I couldn’t find was a way to edit the name of the overall sector. Is there a way to do that yet? If not, would you be able to add that ability? If you could, this app would be perfect!

The App is Broken

It just won’t open.

Bizarrely addictive

I mean, it’s not even a game, really. But it is super fun to build a sector and look around and it then imagine the story (and edit it).

There are some spelling errors which don’t effect the use and I’m guessing mean this is created by a non native English speaker (TL9 features “atrifical gravity” for example :) ). It doesn’t affect the use, just pointing it out. Good job on this app.

UPDATE: unfortunately, the app has become unresponsive. Now it starts to launch, shows the last system I was looking at, then crashes. Turned off phone three times, same result. A pity. This was my favorite new app. :(. I did find that I can export one system at a time so now I do that regularly and can import if the app dies and needs to be reinstalled but I shouldn’t have to do that. )

OTHER BUGS:
Sometimes worlds will lose their population. The number in the profile stays (3, or 9 for example) but the population number next to that says 0 and I’m pretty sure when it generates there were numbers there because I had recorded them.
