About
use.fo is an AI voice typing keyboard for iPhone. Speak naturally from the keyboard, choose a mode like Email, Work, Translate, Social, or Proofread, and get polished text inserted back into the app where you were already typing.
It is built for mobile-first professionals, support reps, salespeople, PMs, marketers, creators, and heavy AI users who want better text without switching between an AI app and Messages, Gmail, WhatsApp, Slack, LinkedIn, or Notes. Prompt shortcuts also sync through the user's own Google Drive, so reusable replies and writing templates stay portable without becoming another third-party prompt database.
The product stands out because it moves the AI writing workflow into the keyboard instead of asking users to copy text back and forth from a separate AI app.

In practice, 13 million registered users didn't convert to shoppers at any meaningful rate. Most commerce revenue came from the web, not the app. The mental mode of using a utility or social app doesn't automatically include buying — that purchase habit has to be built separately.
except for the getting attention there's no incentive to hold back features like launching a big 3.0 where you're doing a paid update where everybody's paying you for the features... I should have just launched them and kept moving.
Subscriptions Make Every Small Update a Revenue Opportunity — Stop Saving Features
In the paid-upfront era, holding features for a major version made sense — the new paid SKU was the monetization event. Subscriptions changed everything: the user is already paying, so every shipped feature compounds the perceived value of the subscription being renewed. David explicitly names this as the cognitive update he failed to make: subscription business model, box-software launch mindset.
There's a play for whatever you're stuck on.
