What this app is. What it isn’t. What you could build.

One-liner

T-Minus is a real-time space launch tracker that shows upcoming rocket launches with countdowns, live updates, and mission details.

Strengths

Provides accurate, real-time launch countdowns and status updates ("The countdowns are precise and the app updates instantly")
Offers detailed mission info including payload, rocket type, and launch site ("Great breakdown of what each launch carries")
Clean, minimal interface focused on launch data without clutter ("Simple design makes it easy to scan what’s next")
Tracks both NASA and commercial launches (SpaceX, Rocket Lab, etc.) across multiple global sites
Push notifications for launch events and delays ("I got alerted when Starlink launched—perfect timing")

Weaknesses

No offline access to launch schedules or past missions ("Would be great if I could check launches while flying")
Limited customization—users can’t filter by rocket type, country, or frequency ("I only care about SpaceX; why show everything?" from 3+ reviews)
Some users report inaccurate delay alerts ("App said a Falcon 9 was delayed, but it launched on time")
Lacks integration with calendar apps or reminders ("Would love to add launches to my Google Calendar")
No historical archive of past launches beyond recent ones ("Where are launches from last year?")

Opportunities

Build a lightweight, offline-first version with cached launch data for travelers or remote users
Add customizable filters (e.g., only SpaceX, only orbital launches, only launches in the next 7 days)
Integrate with calendar apps to auto-schedule launch reminders and events
Create a 'Launch History' tab with searchable archives and mission timelines
Add user-generated notes or personal tags for favorite launches (e.g., "My first launch watch")
