Accountability That Actually Works
Whistl connects you with your mate to create mutual accountability. Set restrictions together, get real-time alerts, and support each other's journey to healthier gambling habits.
Mate-Based Restrictions
You and your mate set gambling restrictions for each other. Want to change limits or access blocked apps? You'll need to ask your mate for permission first.
Real-Time Alerts
When you try to access a gambling app during blocked times, your mate gets notified instantly. True accountability in real-time.
Custom Time Blocks
Set personalized restrictions together - from 24/7 blocks to allowing just 5 minutes a day. Your mate controls your limits, and you control theirs.
AI Weekly Reports
Get AI-generated insights into your gambling behavior patterns. Understand your triggers and progress with detailed weekly reports you both can review.
Shared Statistics
Track your progress together with detailed stats on blocked attempts, time saved, and milestones achieved. Transparency builds accountability.
Healthy Balance
