Not really a Pen Pal app

I found this app when I searched pen pal and it looked really cute so I downloaded it. The layout is super cute but it's not exactly what I thought it was. I received postcards mostly from Korean males, which I was okay with at first since I love kpop, but when I would find out their age and would stop talking to them (I'm 17). After two days of having the app I sent out a lot of postcards just asking people for their age. The majority of (male) users are Korean and Japanese around 20-30 years old. I then googled what Doki Doki meant and found out that it's a Japanese Onomatopoeia for a heart beat. So if you're around 20+ years old and looking for an international friend or significant other then this app is for you.

Wish there was an age range option

This is a really nice app it lets one meet people from all over the world which is nice however there are some ways this can improve thus I gave it 4 stars. I recommend for this to perhaps in the future have the option to be able to choose the age range when sending the postcards.. It be really nice if it does that.

I'm 17, I have bumped into 24+ year olds and worse a 53 year old.. I would really love to be able to message the people close to my age group wether 1-2 years older or younger than me but not 5-6 years older! Majority of people in this app practically ARE 20-30 years old it's kinda a big turn off when wanting to meet people at least near my range. Being able to create friends of my age would be really nice because then we won't have much age differences because majority I meet are more older and that really doesn't help me create friends. (Even though this app is a send postcards everywhere)

There are some perverts in there too claiming that they're horny and this was very disturbing. I always report these people or ignore their messages and delete ugh. (Again just by the 22+ years old do this it seems) I am not comfortable speaking to adults I prefer to have a better communication with someone near my age. If you are in your 20's though then you are in luck this app is really filled with people on their 20's. Not really for people in their teens to find other teens.

Long time user!!

I have met some really close friends. I'm super dedicated to the close friends that I have met on this~! I have met awesome kpop fans! Then I have met Kpop fans that won't shut up about Kpop 24/7.. It gets annoying. Especially when they wonder why Korean people won't tolerate them for much longer. There used to be a lot of perverts but I'm glad that died down a bit! I have even been able to go on dates thanks to this app! I love that I can meet a variety of international people! Well more so people from the USA, Korea and Japan lol. With all of the close friends that I have made, I have received many snail mail letters and packages!! So awesome!! :D I have been using Dokidoki for 3 years now! I will keep using this app in anticipation of meeting more amazing new people and having more new off app social opportunities~!!
