THREE RATINGS. YOUR OWN PATTERNS.
Energy and focus
don't always
keep the same hours.
You can feel energetic and still struggle to concentrate. BPTF lets you look at energy, focus, and motivation separately, as well as in one combined chart.
- 01 Compare average ratings by hour.
- 02 See the entries and days behind your results.
- 03 Spot gaps where you haven't logged yet.
Your charts reflect your own check-ins. More days and a wider spread of hours give you more context.

A few useful answers.
What is biological prime time?
Your biological prime time is the part of the day when you tend to feel most energetic and focused. BPTF helps you explore that pattern by comparing your own ratings across different hours.
How long should I track?
Start with quick check-ins at different hours across multiple days. Patterns become easier to interpret as you collect more entries. There is no fixed number of days that guarantees a clear result. The app shows how many entries and days contribute to your charts.
Does the app measure my energy automatically?
You rate how you feel yourself, from 1 to 10. BPTF calculates hourly averages from those entries. It does not use sensors or wearable data, and it is not a medical assessment.
Can I set reminders?
Yes. Choose your tracking hours and a reminder minute in Settings. You can also keep your previous ratings selected, then adjust them for your next entry.
Do I need an account or internet connection?
No account is needed, and tracking works offline. Your entries stay on your device. Sending optional feedback requires an internet connection and shares your message and optional email with support.
Is the app free?
BPTF is a paid app for iPhone and Android. Check your store for the current price in your region. There are no ads.
