The app with 1000 users was horribly buggy. Statistically, it crashed 3 times per active user per day (memory leak with photo scrolling). But the thing is that it was crashing 3 times/day and not 1 time/day, meaning that users kept using it. This was 2015, but even today, I'm working on a glitchy unpolished app, and customers just keep using it.

The app with 200 users is http://random-character-generator.com

So generally, I disagree that customers want something fully functional. But fintech is a big exception, because people want something solid before trusting it their money to it. We made up for our glitches by handling payment in person (Automated WhatsApp messages and bank account transfers, rather than shopping carts).

I still think that validation is #1 priority, because you'll probably have to build a dozen prototypes before you get to something people want. Our app with 1k users was ironically a low risk prototype. We were making a recipe app, but decided to test user behaviour by making a low carb variation first. Turned out that there's a lot more demand for low carb recipes than any recipes.
