Hi I am new here!
But I have been developing steem apps for more than four years to name a few

• PlaySteem (mobile steem app)
  https://github.com/EtainClub/playsteem
• ECble (Steem app written in Flutter)
  https://ecble.etain.club
• EtainClub (Instant help, development paused)
  https://etain.club

I guess my work and codes influenced some of steem developers.

I am happy to join this dev community! Thank you @stmpak.wit for letting me know this community. I used to post on the old dev group.

I am happy to announce a brand new app. It is a new service on steem blockchain.
https://etakoo.etain.club

You can find out the details of this innovating service here:

• Empowering Communities with a Revolutionary Coupon Service on Steem Blockchain
• New Steem App - ETAKOO. Mobile Coupon Store

What is the ETAKOO app?

In a nutshell, it is a service where users can sell and buy mobile coupons. My purpose of this service is to bring people from outside of STEEM as many as possible by providing a real life usage of STEEM coin.

It is an alpha stage

There are more than 20+ coupon postings:

The app is for mobile coupon selling and buying but users showed that the service can be used for many different kinds of purposes such as holding an event.

Update 0.5.0 (Alpha)

I opened this service quite early even though the progress was not completed because I wanted to keep my words.

But now the service is quite stable. I improved the app a lot in recent days with hard working.
Here are updates:

• Easy steps to create a coupon post
• Caching the coupon posts
• Pagination
• Partial Internationalization
• Draft
• Show top coupons and related coupons
• Fancy UIs
• Support Keychain and posting key

The Future?

These are the coupons that I purchased:

It is a fun to collect coupons, which can be used in real life to purchase goods and services.
I hope new comers to Steem have interest in this service and stay in Steem community!

Now the coupon part is prepared. The next will be the community part in which new comers create posts.
