Muslims Day
মুসলিমস ডে
Muslims Day is a free Islamic companion app with 6.6M+ downloads, kept running by its users' donations. Paid media had to grow donations, not just installs. As Media Buying Strategist I helped build the strategy and the setup underneath it: content, ad account and data integration, SDK and Firebase, push notifications and CRM on GoHighLevel, and budget optimization. Eight months later, donations were 2.5 times higher.

The brand
Muslims Day covers a Muslim's day from Fajr to Isha: prayer times and alarms, the Quran with translation and tafseer, duas, a Qibla compass, a digital tasbeeh, nearby mosques and the Mahfil video feed. It started in 2015 as "App of Ramadan" and now runs as a software initiative under Kahf.
The core features are free for everyone. The team is funded by a premium subscription and, above all, by users who choose to give. That makes donations the number that keeps the app alive.

How supporters give. Donations happen outside the app, on a separate Support Us page:
The challenge
With millions of free users, growth was never about reach alone. The goal was more people choosing to support the app, and four things made that hard.
The approach
Tracking came first. Once every platform could see a donation, content, re-engagement and budget decisions could all run on the same signal.
The execution
Each track fed the others: measurement told content and budget what worked, and the CRM turned new donors into returning ones.
I set up the ad account structure and connected donation data back to the ad platforms, so campaigns could optimize for real supporters instead of cheap clicks. In the app, I implemented the ad SDKs and Firebase to track the journey after install, with key events feeding both analytics and campaign optimization.
I built the content plan around why people already give to Muslims Day: it helps millions of Muslims with their daily ibadah. Creative led with the app's value and the reward of supporting good work, then made the ask, in Bangla and English.
I connected push notifications and the CRM through a GoHighLevel setup. Users could be segmented by behavior and support history, then re-engaged with the right message. Paid media brought people in; the CRM and push brought them back to give again.
With donation data in place, I shifted spend toward the campaigns and audiences producing donors. Budget was reviewed and reallocated on an ongoing basis: underperformers were cut, winners were scaled.
The results
Beyond the headline number, Muslims Day came away with a growth system it can keep running.
Muslims Day already had the audience and the trust. My job was to connect every ad to a donation, then bring supporters back.

My role
What I took from it
Once platforms could see donations, optimization did the heavy lifting.
The first gift is the start; push and CRM make the second one likely.
Respectful, value-led messaging fits an audience that uses the app for worship.
Why this case matters
Muslims Day didn't need louder ads. It needed ads that could see a donation, content that earned trust, and a way to bring supporters back. Putting those together grew donations 2.5× in eight months, for an app that keeps its core features free for everyone.
