Building mobile apps people actually keep using

Most apps lose the majority of their users within the first few weeks. The ones that survive share a few traits: they solve one problem very well, they're fast, and they respect people's time and data.

Principles we build by

• Design for real conditions — slow networks, older phones, busy people.
• Get users to their first success in under a minute.
• Measure what people do, then remove what they don't need.
• Treat performance and accessibility as features.
• Ship small improvements often instead of big releases rarely.

Great products are rarely finished at launch. They get great through steady, evidence-driven iteration with the people who use them.
