Both work. They serve different practitioners. Here is the honest breakdown of when a spreadsheet is enough and when you need a real app.
A Google Sheet, Excel file, or Notion database is the original BJJ tracker. Many serious practitioners have used one for years. The pros are real and the cons are also real.
A purpose-built BJJ app like BJJ Belt Progress trades flexibility for momentum. You give up custom columns; you get IBJJF math, mobile-first logging, and pattern analysis.

| Mobile session logging | Slow | Fast |
| Pattern detection | None | AI-powered |
| Reminders and streaks | None | Built-in |
| Backup and sync | Manual | Automatic |
| Customization | Unlimited | Limited |
| Setup time | 1-3 hours | 2 minutes |
| Maintenance | You do it forever | App handles it |
| AI coaching | None | NORTH |
Use a spreadsheet if you train BJJ casually, do not care about IBJJF eligibility timing, and just want a long-term log of dates. Spreadsheets also work for practitioners who already have a strong tracking habit and only need somewhere to dump notes after class.
Use an app if you train consistently, care about your time-in-grade, want to see patterns across hundreds of sessions, or simply want progression tracking that does not require thirty seconds of your time after every class.
Some practitioners use both. The app handles daily session logging and progression scoring. A separate Notion doc or Sheet stores long-form notes on technique drilling, competition prep, or specific partners. Each tool plays to its strength.

Download — App StoreA spreadsheet works for casual logging if you train less than twice a week and do not care about IBJJF eligibility math. A real BJJ app is needed once you train regularly and want measurable progression toward your next belt.
Yes, but it requires custom formulas to calculate IBJJF time-in-grade, and most practitioners give up updating it within three months. The friction of opening a laptop after class is the silent killer of spreadsheet trackers.
IBJJF-aligned progression scoring, AI-driven pattern detection across debriefs, evaluation readiness flags, mobile session logging in under ten seconds, and weekly summaries that surface trends you cannot eyeball from a sheet of dates.
Yes, plenty of practitioners maintain Sheets or Notion docs for years. They work for raw log-keeping. They fail at giving you actionable signals about your readiness for promotion.
If you are happy logging dates and never analyzing them, no. If you want IBJJF-compliant scoring, AI coaching, and progression insights without manual work, the app pays for itself in time saved.
Some practitioners do. Use the app for daily session logging and progression tracking, and a spreadsheet for long-form notes on specific techniques or competition prep. They serve different jobs.

Practitioners who understand the IBJJF system make better training decisions, communicate clearly with their professor about promotion, and recognize when they have actually met the minimum requirements versus when they are still building.
Most BJJ practitioners overestimate their training consistency. Tracking accurate session counts reveals the truth. A practitioner who feels they train four days a week often logs only 12 sessions per month — three days weekly when measured. The data discipline of logging sessions exposes the gap between perception and reality.
Whether you train at a Gracie Barra in São Paulo, a 10th Planet in Los Angeles, or a small independent academy in your hometown, the IBJJF standards remain the same. Belt rank is portable. Time-in-grade requirements are universal. The progression criteria do not vary by academy. This consistency is what makes BJJ ranks meaningful globally.
The BJJ Belt Progress app calculates your IBJJF eligibility based on the same algorithm professors use to evaluate progression. Free 14-day trial.
