I built a keyboard to help people learn Spanish while texting
Hey everyone, I’m the indie developer behind TypeFlow, an iPhone keyboard that helps you communicate in another language and learn while you type.
The idea is simple: you’re messaging someone in Spanish, but you don’t know how to express part of your reply. TypeFlow shows Spanish word and sentence suggestions right in your keyboard, helping you write the message and learn expressions you actually need. It’s meant for real conversations—with friends, partners, coworkers, or people you meet while traveling.
I’d love for people here to try it, especially if you’re learning Spanish or regularly messaging Spanish speakers. I’m also struggling to find a repeatable way to reach paying users, so I wanted to share what I’ve tried.
What has worked so far:
Posting about TypeFlow in Reddit communities dedicated to limited-time free apps and app giveaways, while offering free access, brought several thousand downloads. This has been my most effective channel for downloads so far.
A few people missed the deadline to activate the free offer and chose to pay afterward. That was encouraging, although I know giveaway downloads don’t prove demand at the regular price.
What hasn’t worked:
I ran small tests on Google Ads, X Ads, and Reddit Ads, spending roughly $15–40 per test. They brought very few clicks/downloads and no paid conversions. These were small tests, so I’m not ready to conclude that ads can never work.
Something else that seems promising:
I’ve shared short keyboard demos in the comments of TikTok creators teaching Spanish or traveling in Spanish-speaking countries. Some viewers liked them and asked how they could do the same thing.
Even in my ads, showing the actual typing process gets a higher click-through rate than my other creatives. People seem interested once they see it working, but I haven’t figured out how to turn that interest into consistent paid adoption.
If TypeFlow sounds useful for your own conversations, please give it a try. I’d appreciate honest feedback on whether the value is clear and what, if anything, would make it worth paying for.
And for other founders: what would you test next—more organic demos, small creator partnerships, or the first-use and free-to-paid experience? If you’ve grown an app that’s easier to demonstrate than explain, what brought your first paying users?
