The best mini app builders optimize for building on mobile. A few general tips for making best-in-class mobile mini apps:

1. Simplify screens

2. Make buttons and touch targets bigger

3. Remove unnecessary crypto jargon and UI complexity

Example: Crowfund mini app

Here's an example on how to improve a popular mini app, Crowdfund.

1. Consider moving anything optional to after you complete the primary action, so in this case the comment would come after the donation

2. Make the primary action -- adding a donation amount -- bigger and place it front and center

3. USDC + logo, the wallet selected are not useful for 95% of people

4. The available balance is useful, so consider making that a clear secondary piece of info

5. Make the primary button big and easy to tap on a mobile device.

Here are the current priorities:

1. Crypto

• Wallet

  • Focus is still growing usage — over 95,000 funded wallets!

  • Second focus is on making mini apps better — new dev tools this week!

  • Deprecating Frames v1 — exploring a date

2. Social

• Storage Redenomination

• Signups for Free with social proof

3. Protocol

• Snapchain migration — please move over to Snapchain

  • Launch Overview
