These are all what are termed "escrow miners" or "faucets", so you're not grinding CPU or battery. Not all of them require an invite code, but any with "security circle" structures and similar will grant a higher mining rate. They are all mobile apps, but not all have both Android and iOS versions, and you might have to get Bee directly from the website rather than your mobile's "store". Get the Bluestacks utility for your desktop computer if you want to run them there. Set up timers in your Clock app to start dinging before mining sessions are about to expire (this is ideal because clock timers are considered high-priority, and will override your setting to turn off most notifications, which most of us do for sanity reasons).

Other coins: there are hundreds of apps out there, most of them scams, that promise coins after doing repetitive menial tasks, solving captas and so forth. Ripple Faucet, for example, didn't make the cut here because it requires attention every eight minutes for a reward that amounts to pennies per day. I've winnowed it down to these, as they have active development and/or a "white paper", or are already an established coin.

The list is in rough order of eventual perceived coin value and/or "annoyance factor".

Optimization tips and tricks....

• Bee: restart the miner once per day. Pi Network: restart the miner once per day, and set up the security-circle “shield” after three days. Time Stope: click the calendar and push the button once per day. CowCow: max the stover basket before doing anything, and play the "bonus" game (but no more than once between each 2hr session). GeoCash: enable locations and take your phone everywhere. Crypto Treasures: start the Open Chests and Watch Videos quests (etc) before doing activities that give or subject you to them, and do not buy the blockchain chest unless you know what you're doing (because that one costs PHT). Pi, Bee, and Crypto Cards: always x2 the wheel. ALL: never pay real money for anything unless you know what you're doing, we're here merely to "raid the buffet table" for free coins. ALL: for the love of god, back up your private keys so you can keep going on another device if your first is lost, stolen, or wrecked. (Standard crypto stuff. Don't be that guy crying in a landfill looking for a lost drive.)
