NMS Logbook

NMS Logbook is your personal record of the systems and space stations you find in No Man's Sky. Everything is stored on your device — no account, works fully offline. Add it to your home screen (Safari → Share → Add to Home Screen) to run it like an app.

The flow: Log a system while you play → browse it later in the Catalogue → let the app surface trade loops, envoy runs, and crafting sources from your own finds.

The tabs along the bottom:

• ✎ Log — record a new system (or edit one).
• ☰ Catalogue — search and browse everything you've logged.
• ⟳ Routes — trade loops, region guilds, and envoy visit lists.
• ⚗ Craft — recipes and where to source their ingredients.
• ◎ Goals — a to-do list for in-game objectives.
• ⬢ Corvette — turn a build's parts list into a gathering checklist.
• ⚙ Settings — sync, backup, envoy rules, and this guide.

On the Log tab, fill in what you see on the galaxy map and in-system. Only the name is required, and it must be unique — if you re-use a name (or something very close) the app warns you before saving.

Pick economy, strength, and conflict from the flavour words the game shows you (e.g. "Research", "Wealthy", "Pirate Controlled"); the app normalises each to its real type, star-tier, and trade loop and shows the prediction inline. Choosing a Black Market economy automatically marks the system Pirate Controlled.

• Region — envoys cluster by region, so this drives station predictions.
• Race — picking an inhabited race (Gek/Korvax/Vy'keen) auto-adds a space station for you.
• Star — its stellar metal is added to Resources automatically (marked ★, can't be removed).
• Resources / Tags — type and press Enter to add chips; ✕ to remove. Suggestions come from known items and things you've used before.
• Portal address — opens a glyph keypad; tap glyphs to fill the 12 slots.
• Galaxy — remembers your last one so you rarely need to touch it.

Tap Log system to save. You land in the Catalogue with the new entry.

Tap the station row on the Log form to open the station editor. Give it a prefix (auto-filled from the system name) and a suffix — the suffix hints at which guild envoy lives there (Merchant, Explorer, or Mercenary), something the game never tells you directly.

Every envoy guess is a prediction you can override per station. The prediction blends the region's guild, the suffix's seeded default, and your override. If a suffix's usual envoy disagrees with what's actually here, you get a ⚠ heads-up.

• Redemptions ⬆ — what the envoy offers for standing.
• Donations ⬇ — what it accepts for standing.
• Prefill … staples — one tap adds that envoy's usual items (never overwrites yours).
• Trade goods ↗ / Sell here ↘ — read-only, derived from the economy: what to buy here and carry onward, and what sells at a premium here.

Outlaw (Pirate Controlled) systems swap the envoy for a ☠ black market contraband list instead.

In the Catalogue, press and hold (or right-click) a station row to view its details read-only.

The Catalogue lists every system you've logged. The search box matches across names, regions, economy, resources, tags, notes — anything on the card.

Stack the dropdown filters (economy, strength, conflict, race, envoy, region, resource) to narrow down; they combine with AND. The ⚠ Suffix-seed conflicts only toggle surfaces stations whose real envoy differs from what their suffix usually implies — handy for cleaning up predictions.

Each card has Edit and Delete. Use ＋ New to start a fresh log.

The Routes tab turns your logbook into itineraries:

• Trade loops — your systems auto-slot into the two NMS economy cycles. Buy each node's surplus, sell at the next. Filter by minimum strength (default: strong ★★★).
• By region — set a region's guild, or leave it Auto to infer from confirmed stations. This drives envoy predictions for the whole region.
• Envoy loop — pick Merchant/Explorer/Mercenary and tick off stations as you visit them. Marks persist per type; Reset clears just the shown type.
• Envoy exchange — pick an item to see which stations offer it and which accept it.

Search any item on the Craft tab to see how it's made and where you can get its parts. Recipes show inputs → outputs; tap any ingredient to drill into it, and Back to return.

• ✓ buildable marks recipes whose ingredients you can fully source from your logged systems — even transitively (parts of parts).
• Source the ingredients expands to show which of your systems gather, refine, or trade each input.
• Where to find lists where an item is gathered ⛏, offered by envoys ⬆, or wanted ⬇.
• ★ Watch an item or pin a recipe to keep it at the top for quick reference.

Your discoveries carry across playthroughs, but what you've found in each one doesn't. So the catalogue is shared by every save, and each save keeps its own list of the systems you've actually found in it.

Only those systems feed Routes, Craft sourcing and the region rollup — a system you logged in another save won't send you flying to a station you can't reach yet. Corvette builds and envoy-run ticks are per-save too; goals and watched items are shared.

Tap the save name in the header to switch, or pick All saves to drop the filter and see everything at once. On the Catalogue, the In / Not found / All row lets you browse systems you haven't found yet and tap + Add to save to mark them off. The same toggles live on the entry form under “Found in”.

Create, rename and delete saves in Settings → Saves. Deleting one never deletes systems. Which save you're on is per-device, so your phone and desktop can be on different playthroughs.

A simple to-do list for what you're chasing in-game — resources to farm, systems to find, upgrades to build. Add a goal with optional comma-separated tags, then search, filter by tag, tick them off, or hide the done ones. Open goals sort to the top.

Create a build, then paste a tutorial's parts list (lines like Hab: 2) to turn it into a gathering checklist. The parser is lenient and asks you to resolve anything ambiguous or unrecognised.

Use + / − to track how many of each part you've gathered; the progress bar fills as you go. Tick a part to mark it fully stocked, hide stocked parts, or add parts by name manually.

Everything lives on your device. To share a logbook across phone and laptop, use Sync (below): generate a code on one device and enter the same code on the other. The code is both the key and the login, so keep it secret — anyone with it can read and write that logbook. A different code = a separate logbook.

Prefer files? Backup & transfer exports the whole logbook as JSON and imports it back — Merge to combine, or Replace all to overwrite.
