How does M-Pesa STK Push work in a mobile app context?

STK Push triggers a payment prompt directly on the user's phone — the app sends a request to Safaricom's Daraja API, which pushes a payment request to the user's SIM card. The user enters their M-Pesa PIN on their own device (not in your app), and Safaricom confirms the transaction to your API.

What are the key differences in building for Nairobi versus a European market?

Key differences: payment infrastructure (M-Pesa vs. cards/banking apps), device landscape (affordable Android vs. premium mix), connectivity (variable 4G vs. reliable broadband), language (English/Swahili bilingual considerations), and user sophistication pattern (mobile-native digital skills vs. desktop-transitioned users).

Mobile App Development in Nairobi

Nairobi's mobile app market is defined by M-Pesa — Kenya's mobile money infrastructure that processes more transactions than PayPal. Building mobile apps for Nairobi means building for a market where the mobile phone is the primary computer, M-Pesa is the primary financial infrastructure, and the user base is young, digitally native, and growing rapidly.

Mobile Apps Challenges Specific to Nairobi

Operating in Nairobi creates distinct pressures that businesses elsewhere don't face. Here's what we see most often.

1
M-Pesa integration is not optional for Nairobi consumer apps — it is the default financial interaction for Kenyan mobile users
2
Nairobi's mobile internet is predominantly 4G with variable quality — apps must load quickly and function on constrained bandwidth
3
Android dominates Nairobi's market at 85%+ — budget Android optimization is critical for reaching Nairobi's mass market
4
Kenya's digital services tax and emerging data protection regulations create compliance requirements for apps monetizing Kenyan users
