The right front door, not the fashionable one
An app store listing is a distribution choice, not a quality one. Plenty of the best software I've built never asked anyone to install anything — it opened in a browser tab and worked. I'll recommend whichever front door actually fits your audience, including the one that earns me a smaller invoice.
You talk to the person writing the code
There's no account manager relaying your question to a developer and the answer back to you. That's the main reason I keep the client list short: it only works if I have the room to do it properly.
Built to be handed over
Documented, conventional, and free of clever tricks only I understand. If you ever need to bring the work in-house or hand it to someone else, that should be a decision you get to make — not a wall you hit.
Shipping isn't the finish line
Software decays quietly. I'd rather stay with a project and keep it healthy than hand over a zip file and wish you luck.
