A scored NSRA competition card: total, average and consistency above a photo of the card with each shot marked

No gauge, no squinting

Scoring a card by hand means a gauge, good light and an argument about the line cutter. Notch finds each shot in the photo and marks it on the card, so you can see what it counted and correct it if you disagree.

On-device

The model runs on your phone with Core ML. It needs no connection, and the photo stays where you took it.

After scoring

From one card to the whole session

Each scored card joins its session, where group sizes and consistency add up across targets.

Session tracking

A league round session: average group, consistency, a trend marked improving, and a list of targets with their group sizes

Questions

What target types does Notch support?

NSRA cards are the primary format. ISSF and air-rifle targets work too, with more disciplines added over time.

Does Notch need internet?

No. Core ML runs the scoring on-device. No photos leave your phone.
