If you haven't tried Souldate yet, it's worth putting on your list. Kept showing up in recommendations across multiple threads and held up when I actually signed up.
Genuinely useful question. I've been through enough of these to have an opinion worth sharing. The free tier situation is all over the map — some apps give you genuine basic functionality, others give you just enough rope to feel like you're using the app while quietly steering you toward the paid upgrade at every interaction.
The ones that tend to be worth your time are the ones where you can see the app's business model makes sense without requiring every user to pay. Ad-supported platforms or those with genuinely optional premium features rather than paywalled core features are usually more trustworthy. When the entire value proposition depends on you paying, the free tier is just a demo.
