Apps

Small apps, built by Aunova.

Android apps we design and build in Rust with Slint. Each one does one job and explains itself plainly.

BluBelt

A martial arts training log on the BJJ belt system.

  • Log each session with its date and the martial art you trained.
  • Your belt and stripes fill in as sessions add up, and you set how many sessions a stripe takes.
  • Stats per martial art for this week, this month, this year, all time or any date range you pick.
  • Works offline with no account. Your log stays on your phone.

Free, with one banner ad after you give consent. Pro is a one-time purchase that removes the ads and adds backup and restore.

  • BluBelt home screen: a blue belt with three stripes, 390 total sessions and 50 sessions to the next stripe.
  • BluBelt Log tab: sessions this week and this month, the day streak, and a form to log a session by date and martial art.
  • BluBelt Stats tab: a date range picker and sessions per martial art with their share of the total.
  • BluBelt History tab: past sessions by date and a session count per discipline.

ModelMeter

See which local AI models your phone can run.

  • Reads your phone's hardware, including its memory and storage.
  • Lists the local AI models from a curated Hugging Face snapshot that fit, grouped by how well they run.
  • Shows the math for each model: the model file, the context reserve and what it needs in total.
  • Filter the list by download size and tag.
