About this app

🖖 CAPTAIN'S LOG OF STAR TREK

Captain's Log of Star Trek is a Star Trek fan companion for captain's logs, stardate calculator, LCARS-style bridge screens, starship sounds, 3D ships, daily missions, officer ranks, and sci-fi roleplay. Record mission logs, convert dates to stardates, explore starships, and turn your Android device into a personal command bridge.

Built for Star Trek fans, Trekkies, cosplayers, roleplayers, and sci-fi fans who want more than a simple stardate converter.

📖 CAPTAIN'S LOG & SPACE JOURNAL

Create captain's log entries for real memories or fictional missions. Add titles, notes, photos, and voice memos. Use it as a daily journal, travel log, convention journal, roleplay log, or fan-fiction notebook. Export selected logs as PDF or TXT.

📅 STARDATE CALCULATOR & TRACKER

Convert calendar dates into stardate-style readings in seconds. Save today's stardate, past events, anniversaries, conventions, fictional missions, or future dates. Add stardates to your captain's log and keep your mission timeline organized.

🖥️ LCARS-STYLE STAR TREK BRIDGE

Open a futuristic LCARS-style command interface inspired by classic starship computer displays. Explore animated panels, deep-space colors, cyan HUD details, command themes, and bridge controls for immersive Star Trek roleplay and sci-fi ambience.

🔊 BRIDGE SOUNDBOARD & SCI-FI SOUNDS

Use a sci-fi soundboard with bridge beeps, computer tones, alerts, door effects, interface sounds, and starship ambience. Great for cosplay, roleplay, tabletop sessions, fan gatherings, watch parties, writing sessions, or a sci-fi desk setup.

🛸 3D STARSHIP VIEWER

Rotate, zoom, and inspect detailed 3D starships from multiple angles. Explore command ships, science vessels, cruisers, and other spacecraft, choose a favorite vessel, and build your starship collection.

👨‍🚀 OFFICER PROFILE, RANKS & SERVICE RECORD

Track your activity like a personal Starfleet-style service record. See captain's logs created, voice-log duration, daily missions completed, games played, streaks, badges, rank progress, and command milestones. Rise through officer, captain, and admiral-style ranks.

🎯 DAILY MISSIONS & FEDERATION CREDITS

Return to the bridge for quick missions. Record a log, calculate a stardate, explore a starship, complete a bridge activity, maintain your streak, and earn Federation-style credits for progression.

🎮 SCI-FI MINI GAMES

Play quick memory and Star Trek-inspired challenges between log entries. Test your recall, complete short bridge tasks, and add more interaction to your command routine.

✨ CAPTAIN'S LOG PRO

Unlock unlimited captain's logs and additional premium features, including expanded log capacity, premium themes, captain and admiral-style badges, welcome credits, and customization.

This is a scam. It was listed as free, as in it normally has a price. Then when I opened the app, it immediately wanted me to get a subscription. That's pretty scummy.

Thank you for the feedback. We’re sorry the experience felt misleading. Captain’s Log is free to download and includes free features, while some advanced tools are optional through a subscription. We’re reviewing the opening experience to make free and premium options clearer. We appreciate you pointing this out. Live Long & Prosper 🖖
