An app for people who take shooting seriously
Sport shooters need to keep track of training sessions, ammunition usage, firearm maintenance, and document validity. Most do it in their head, on paper, or in Excel.
Paper and Excel
Records scattered across notebooks, notes, and spreadsheets. Nothing tracks maintenance or document expiry.
What shooters were dealing with
- Training session records scattered across paper and Excel.
- No overview of ammunition usage per individual firearm.
- Firearm service and document expiry are easy to forget.
- Nobody wants to put sensitive firearm data into someone else's cloud.
What the app delivers
- A training diary with a calendar, target photos, and notes.
- Firearm and ammunition tracking with automatic round deduction.
- Smart reminders for maintenance and upcoming expiry dates.
- 100% offline, your data stays only on your phone.
