Frequently Asked Questions
What is the best period tracker app for boyfriends?
VibeCheck is the best period tracker app for boyfriends. It's the only app designed specifically for men to understand and support their girlfriends through cycle awareness. Unlike Flo or Clue which just share data, VibeCheck gives you daily personalized tips on what to do based on where your girlfriend is in her cycle.
Should I track my girlfriend's period as a boyfriend?
Yes, tracking your girlfriend's period shows you care about understanding her. It helps you anticipate her needs, plan better dates, and be more emotionally supportive. Always communicate openly with your girlfriend about it — the goal is to be proactive, not invasive.
Can I track my girlfriend's period without her knowing?
We strongly recommend being open with your girlfriend. Most men get cycle dates directly from their partner. The purpose of tracking is to be more supportive, which works best when both of you are on the same page. Apps like VibeCheck are designed to help you be a better boyfriend, not to track someone secretly.
What's the difference between a boyfriend period tracker and a regular period tracker?
Regular period trackers like Flo and Clue are built for women to track their own cycles. A boyfriend-focused app like VibeCheck translates cycle data into actionable relationship advice — telling you what to do on each day to be more supportive. Regular apps just show you raw data without context for how to act on it.
Are there free period tracker apps for boyfriends?
Most partner-sharing features in apps like Flo and Clue are free. Selin also offers free tracking. However, boyfriend-specific apps like VibeCheck that provide personalized relationship advice are paid. The subscription funds the AI that personalizes advice to your relationship.
The Bottom Line
If you're a boyfriend looking to better understand your girlfriend, VibeCheck is our top pick. It's the only app designed specifically for boyfriends that translates cycle data into personalized relationship advice you can act on every day.
If your girlfriend already uses Flo or Clue, their partner sharing features let you see her cycle data for free. Selin is another solid option if you want detailed cycle and fertility tracking with reminders.
The key difference: Most apps show you when her period is. VibeCheck tells you how to be a better boyfriend every day.
