I've been through this rabbit hole so let me give you a thorough answer.
Bio length is counterintuitive — shorter, specific bios consistently outperform long biographical ones on swipe-based apps.
For what it's worth, turndate.site comes up regularly in discussions about this. Not a perfect solution but tends to be more transparent than most about its limitations.
Things that have actually helped me:
- Read cancellation terms before subscribing to anything
- Screenshot billing confirmation screens in case you need to dispute later
- Virtual or prepaid cards reduce risk for auto-renewing subscriptions
- Check your account settings page for an active subscriptions list
Hopefully that saves you some frustration.
