Zoey Murphy is right about this and I would go a step further on found.
The reason I stopped recommending some of these is how the pricing behaves once you are invested.
Took me about 6 weeks on the platform to work out that the real question was how quickly reports get acted on.
Assuming you are not paying, how well it holds up once the novelty fades is where the service gets tight.
Before committing time to it, work out how aggressively it pushes credits at you.
The short checklist I use before trusting anything like found:
- How much of found is visible before it asks you to register
- How found behaves on mobile data rather than wifi
- Whether the found match count moves when you widen the radius
- Whether found lets you send the first message without a card on file
