We've been using ShopLystr for a while now. It's a background project I pick up every now and then when my wife asks for new features. But it's stable, works cross platform and exactly matches our needs.
I'd decided to try and turn this into a product for others to use. I have no idea what I'm doing, but I do know I need to be able to take payments...and that's really about it. Rolled in stripe support and made a twitter account.
Since ShopLystr is so useful for us, I know other will find it useful as well. It's just a matter of informing people. This is where I'll need to figure out marketing in some form or fashion.
I have an indie comic oriented website an twitter I run for fun and have managed to get a decent little following in a short amount of time for an extremely niche market. I'll be taking some of those learnings and applying them here.
I know the most important thing I can do is provide immediate value. I built in the ability for people to use ShopLystr without signups and also share links for anyone to copy. I'm thinking that I can enter people's shopping lists and/or recipes that they put on social media and share it with them. They click on the link, and, BAM, they've got a list ready to go or a recipe saved that they can add to a list at any time. Minimum friction.
As for payment, I'm hoping to find a balance where 70-80% of the users get by just fine with just the free tier. But I also don't want to pipe their data over to advertisers.
I'm thinking of restricting based on private saved lists. The thinking here is that I would be able to create lists of "featured" public saved lists or make them searchable in some way. That way, they'd be providing value to other ShopLystr users. I'd also be able to use that content for promotion on twitter.
However, I have no idea how much to charge for "premium" or even how much to restrict free users.
I guess I'll just have to take a swing at it and adjust on the run. I'll start at $0.99/month or $8.99/year.
