I have been trading in the world of cryptocurrencies for years, I do not say it to give me prestige but only to make it clear to those who are reading that I bought currency, I earned and lost money and I tried every sort of faucet and existing airdrop.
The result of these two years of "experience" I can say with absolute certainty that 90% of sites or apps that allow you to earn free are nonsense.
Can two apps really make you earn something? (Spoiler: yes.)
I ran across two apps called (without too much imagination) "Free BitcoinCash", "Free Litecoin".
The name never as in this case expresses the concept: you will get these two cryptocurrencies for free on your wallet, but how does it work?
Just open the app and click on the claim, at this point in your "budget" inside the app you will be credited with the amount you are entitled to and upon reaching a very small sum ("0.0001" in the case of both BCH and LTC) the sum on your wallet will be automatically credited to you.
Download free BitcoinCash, Download free Litecoin

The photos are of Free Bch but free Ltc is identical only with the violet instead of the green ..
I personally use all these apps and I can guarantee that they pay, the apps are absolutely not a scam as happens in these cases.
