The rule

Now every Upket app starts with one sentence: what does it do in under ten words? If I can’t write that sentence, I don’t start.

• One core action, reachable in one tap
• Works offline first, syncs later
• Ship a demo before polishing

Small apps get finished. Finished apps get used.

This is a sample post — replace it with your own writing.

The sync queue

Each change becomes a small record in a queue. When the phone is online, the queue drains in order:

data class Change(val id: String, val op: Op, val at: Long)

suspend fun drain(queue: Queue) {
    while (true) {
        val next = queue.peek() ?: break
        api.push(next)
        queue.remove(next.id)
    }
}

Lessons

• Test the installer on a clean machine, every time
• Keyboard shortcuts differ more than you think between platforms
