Futari wa Precure

What's come to be known as the Precure series likely wouldn't exist today if it weren't for Sailor Moon, at least not like it now is or as soon as it is, yet the same can be said of many Magical Girl series due to Sailor Moon pushing a few boundaries regarding expectations. Precure in it's own right started it's own trends yet is still an ongoing series, although with multiple incarnations of the same concept. Other series have attempted copying it's success. As such, both these Anime provide a good look regarding the progress/history of the Magical Girl genre. 

There are beautiful girl-warriors, who are looking for crystals. Series have similar number of episodes. There are some cute pets-advisors too. 

both have you finding an animal of sorts that asks you to transform to help save the world. both have you looking for lost crystals. both have a story of finding new friendships.  

Both Sailor Moon & Futari wa Precure are created by Toei, has magical girl concept similar to Sailor Moon. It's directed by Daisuke Nishio of Dragonball Z fame. Also this is for all the anime fan parent out there with young kid: If you have a daughter/child as young as 7 years old, but you can't show Sailor Moon in it's uncut form because of the dark subject matter later in the later season, just use Precure as a 7-8 year old friendly alternative if you're concerned about showing Sailor Moon's uncut content. Precure is more child-friendly for below 9 years old girls if you want to improve their reading skill (Precure is subtitled after all, and the uncut version has no objectionable content other then mild language). read more 

If you like Mahou Shoujo, but want that extra KICK (and I do mean it literally) in your everyday Mahou Shoujo anime, then PreCure is definitely the show to watch. 

Magical girls beating episodic villans through the power of magic and friendship. Precure takes inspiration from Sailor Moon and both of these franchises became the classic mahou shoujo of their era. If you're a fan of magical girls, you shouldn't miss those. 

Both have similar plot designs-- the girls must find and protect an object from evil forces to save the world, with the help of alien companions. Both shows have a strong emphasis on friendship, and both were animated but Toei Animation!  

Both r kinda like power rangers meets magical girl 

i've been watching both recently and thought that a lot of episodes were (unsurprisingly) similar 

it similar both magical appearing giving powers to girls making them magical girls funny,romantic,school life you gotta try it 

~ both have heros/heroines ~ both have mascots that allow them to transform ~ In both animes, they didn't know their partners/allies very well until they became superheroes ~ in both, the mascots can sense if something is wrong/weird ~they both deal with romance/crushes ~ they both have a clumsy main character 

These two shows are both based around being gifted with a extra-ordinary power, In Precure (Prettycure) the two mc's have special cellphones that contain a character that allows them to transform. In Tokyo mew mew, they have power pendents which allows them to transform. They both fight against evil. In Prettycure they fight against the "Dark Zone"s minion whereas in Tokyo Mew Mew they fight against Deep Blue's Minions. In both there is a hint of romance, more in Tokyo Mew Mew compared to Prettycure. In both they gain new powers/members which make them stronger. 

After watching an episode of mew mew power, it would air pretty cure. Both shows are great in it's own way. 

Both are Mahou Shoujo classics which focus on friendship and daily lives of the main characters while keeping their identities as magical girls hidden. In both series the main characters are kind of opposites of eachother (Sakura & Tomoyo and Nagisa & Honoka). The episodic formats are also similar. In both series something (cards and the Dark Zone) cause trouble which the main characters have to fight against. There's also a collecting aspect in both series with cards and Prism Stones.  

both series are old magical girl shows with a girl who uses cards a lot, said girl also has a rich best friend who goes with her in every mission, the only big difference is that in pretty cure, the best friend is also a magical girl where as in cardcaptor sakura, she is not
