I have implemented many things during the last few weeks for the coupon app, which will be called Etakoo.

So I want to summarize the development.

• Dark mode, Custom color UI
• Steem sign-in with posting key and keychain
• Create a coupon post
• Upvote/Password/Coupon Dialogs
• Create a comment
• Purchase a coupon
• Create a purchase transaction
• Display purchased coupons and transactions
• Data caching

Let me show some screenshots one by one.

Home screen

The store and community parts will be implemented later. Here we can see Coupon/Store/Community posts.

As you can see, you can change your favorite color scheme.

Mobile Coupons

This is the main part of this app! Users can sell and buy their mobile coupons. Unfortunately many European countries do not have mobile coupons which are shown here. But it will be popular, I hope, because it is super convenient and is the best way to send a gift to your friends.

A real Starbucks coffee coupon looks like this:

You can exchange this coupon for the coffee which is shown in the coupon.

This coupon app is a place for users to sell and buy these coupons.

Create a coupon post

A coupon post is like a regular steem post but it is formatted through the following steps:

You can add options:

The last is optional benefits which can be offered to buyers.

A coupon post looks like on steemit:

Coupon Details

When you click one of coupons, then you can see the details:

Upvote dialog

You can upvote this post

Purchase Dialog

Yep, you can purchase this coupon with STEEM.

Password dialog

You can purchase this coupon using Steem Keychain as well as your active key.

I will add a recipient field in case that you want to send this to your friend.

Profile Coupon Dashboard

In the profile section, you can see the purchased coupons and transactions

Coupon Dialog

When you click one of coupons (images or transactions), then the following dialog appears.

In real scenario, there will be some kind of a QR code or barcode, so you can purchase the real stuff.

2. A new user gets voted by a voting pool.
3. A new user can buy a mobile coupon such as a coffee coupon with the earned steem.
4. This app is considered as an X2E service.
