Our apps

Small apps that actually help.

Three apps live on Google Play, two more titles in development. Every one of them started with a small, annoying, real-life problem.

Live on Google Play

Did I Lock It

You're ten minutes down the road and the thought hits: did I lock the door? Did I Lock It ends that argument with yourself. Tap once as you leave, and the app remembers so you don't have to.

It's built for the way people actually move through a day — one tap, no sign-up, no ceremony. Add the things you lock, tap them on your way out, and check the log whenever the doubt shows up.

  • One-tap check-in when you leave
  • Track doors, cars, garages, gates
  • Reminders to build the habit
  • Clear history at a glance
  • Works offline
  • No account required

Tan Alert

Sunshine is a timing problem. Tan Alert reads the UV conditions where you are and turns them into a straight answer: go out now, stay this long, cover up after that.

Set your skin type once and the app does the maths in the background — so you come home with a tan instead of a burn.

  • Live UV index for your location
  • Skin-type aware session timing
  • Alerts before you overdo it
  • Best-window suggestions
  • Quick daily outlook
  • Built for real weather, not averages

Video Downloader LCBX

Signal drops. Data runs out. Flights happen. Video Downloader LCBX keeps the videos you're permitted to save on your device, ready to watch whenever the internet isn't.

Pick your quality, save, and everything lands in a tidy offline library. No maze of pop-ups, no five-step download flow — the app does the one job it says it does.

  • Fast, straightforward downloads
  • Choose quality before saving
  • Organised offline library
  • Background downloading
  • Clean, ad-light interface
  • Built for personal, permitted use

Please only download content you own or have permission to save. Respect the terms of the site you're downloading from.
