Salaam - An App to Help Muslims Break the Habit of Viewing Haraam Content

Salaam everyone, A little about me - I'm a Muslim in my 30s living in the West. I do dawah work, especially with youth, work as a licensed family doctor (GP) and also build apps. The problem of p*rn has gotten much worse with modern tech and I've seen the harm it causes, so I made an app to support Muslims trying to stop watching such haraam content. The app is inspired by Ibn Qayyim's Rawdat al-Muhibbeen chapter on addictions and combines that with psychological evidence and CBT-style techniques used in addiction recovery. It runs a 90-day recovery programme, sends reminders, and is kept simple - it tracks streaks, gives rewards for completing daily modules with XP, and even unlocks a little “Jannah garden” as you progress. My long-term idea is to grow this into a supportive community of believers working to purify themselves from this sin. The app is meant to be one piece of a wider plan: regular monthly classes led by mashaykh and experts, ongoing support rather than a one-off fix, and possibly clinics in future. I plan to use a low annual subscription for two reasons: 1) sunk cost effect - people engage more with something they’ve paid a bit for, and 2) a portion of proceeds would fund the teaching sessions and maybe a clinic. I want to use regional pricing so someone in Pakistan wouldn’t pay the same as someone in the UK. I live in the West and my priority is helping people quit the habit, not making a profit. Right now I'm charging $20/year but want to move to regional tiers. Any suggestions on reasonable annual prices for people in the subcontinent, Middle East, North Africa, Central Africa, Far East, etc? I’d really appreciate meaningful feedback and advice, inshaAllah.
