Implement Payment Module For Android App

Job ID: 35750287

Budget: $2,000 – $6,000 HKD

The current app is a music theory practice app
It has a backend that generates music theory exam paper to be sent to the mobile app
There are two modes of generation:
1. exam mode, where the user gets the full paper per generation
2. practice mode, where the user is able to customize the number of each question type
We would like to monetize the generation from the app.
We will have 3 major types of purchases: subscription based generation access, credit based generation access, one-off payment to access the music theory tutorial
Subscription pass (unlimited access “Practice Mode” and “Exam Mode” within the period)
Monthly pass $98/month (promotion $78/month)
Year pass $988/year (promotion $788/year)
ALL ACCESS will be terminated when the pass expires.

Credit based (can be used in “Practice Mode” or “Exam Mode”) with a virtual currency named “B-coin”
FYI, a exam paper cost 100 credits, a single practice question normally cost 1-5 credits (depends on which question it is)

$28/100 credits (promotion $22/100 credits)
$58/300 credits (promotion $48/300 credits)
$188/1000 credits (promotion $138/1000 credits) “best offer”
$338/2000 credits (promotion $288/2000 credits)

We will have a “tutorial function” in the app and it will cost one-time payment of $98 (promotion $48). The tutorial part hasnt been implemented but we still want that part of the payment system be ready.

The payment can be done with apple pay, samsung pay, credit cards and any platforms that usually used in an app (please advise for more details).

Thank you for your time and I am looking forward to working with you. Let me know if you need more information and I am happy to aid you.
