[A daily discovery]

Every day at a time of your choice, SumOne gives you and your partner a question - ranging from deep and introspective to cute and surprising! It’s a chance for you to share more about who you truly are, learn about your partner’s heart and soul, and strengthen your bond!

[A new companion]

Welcome EggMon on your journey! This sweet little egg is fascinated by Love and can't help but be interested in your relationship! Help it grow and hatch into a surprising new form by sharing your honest answers on the Daily Question!


With the pebbles (in-app currency) you collect together within the app, you can buy various items to decorate little EggMon’s room!
Head over to the shop and select your items from the various themes available.
Keep your eyes peeled for the seasonal themes only available for a limited time!

- [Birth Certificate]
It is clear that EggMon is here to stay…How about officially registering its cute nickname?

Every time you answer a question, you can select and share how you’re feeling that day. At the end of the month, our little helper (and EggMon’s best friend) Hakoo will gather it all and share the record of your love with you!

A really cute concept. Pebble collection is pretty slow and the decor is pretty expensive. You'll need to play for several months with your significant other to get a lot out of it. Love the questions, hate the ads after answering questions. Premium version is way too expensive at $13.

adorable concept, but on the second use it kept crashing. i tried uninstalling and installing it again over and over again but i cant get it to load / stop crashing. my friend told me about this app and i was super excited to try it out with my partner but it just doesnt work for me sadly. although if you were to fix the crashing and loading issues, id be using it every day tbh.

LOVING IT!! I have been using this app with my fiancé for a while already and we love it. We are long distance and this app has helped us to remember and value a lot of things with all the questions ☺️ Also the concept of the egg hatching into a beautiful animal is the cutest, the draws and the overall concept is so precious. If you want to have some time with your partner and answer questions about your relationship while seeing a little creature grow, this app is perfect for you!!
