Ten Number Reviews and Details

Questions & Answers

1. What makes Ten Number unique?

   • Every module in every plan. Plans differ only in athlete and coach capacity; attendance, fees, bookkeeping, parent portal, store and automation are never locked behind an upsell.
   • Adapts to the sport. Positions, drill library, tactical board, match statistics and evaluation templates change with the selected sport (15 sports, from football and basketball to swimming, archery and water polo).
   • Runs the business, not only the roster. Automatic monthly fee generation, overdue tracking, receipts, income/expense and account reports sit next to attendance and training.
   • Parents are in the loop. A parent portal shows attendance, fees and announcements; bulk WhatsApp messaging and rule-based automation handle reminders.
   • Privacy by design. Athlete documents and health fields are encrypted at rest (KVKK/GDPR).
   • Web and mobile (iOS/Android) in one subscription, interface in 14 languages, built in Türkiye.

2. Why should a person choose Ten Number over its competitors?

   Most club apps focus on scheduling and team chat. Ten Number covers that, but it also runs the financial and administrative side of a sports school: fee generation and collections, bookkeeping, club store with inventory, staff and leave management, asset tracking. A club owner does not need a second tool for money.

   Compared with desktop-era club software, it is web + mobile, multi-branch, works from the field on a phone, and gives parents their own app view instead of PDF reports.

   Pricing is transparent and local: monthly plans in Turkish lira by athlete capacity, no per-module add-ons, no credit card to start.

3. How would you describe the primary audience of Ten Number?

   Owners and managers of sports schools, academies and clubs with roughly 50 to 400 athletes, mainly youth sports. Three groups use it every day:

   • Owners / administrators track fees, collections, attendance rates and reports on the web.
   • Coaches take attendance, plan training and record match statistics from the mobile app on the field.
   • Parents follow their child's attendance, fees and announcements through the parent portal.

   The primary market is Türkiye; the interface is available in 14 languages.

4. What's the story behind Ten Number?

   Ten Number started inside a sports academy, not a software company. The founder runs a youth academy and kept juggling spreadsheets for attendance, a separate notebook for fees and WhatsApp groups for parents, none of which talked to each other.

   The first version, called "10n", was built in 2026 to replace that stack for one academy. It grew into a multi-tenant platform for sports schools and clubs, with the web app, the mobile app and the parent portal sharing one data model. The name "Ten Number" is the English reading of 10n.
