Web or Android: which one should you pick?

The same account and the same credits, bought in two different ways.

Pick the web if

you do not want anything to renew on its own;
you pay with QRIS (from Indonesia or nearby countries) or by Indonesian bank transfer instead of a card;
you want the most credits for the price: Pro and Max include +10,000 bonus credits;
you want credit packs that last a year.

Pick Android if

you like a plan that renews every month on its own;
you already pay for things through Google Play;
you are outside the countries where QRIS works: Google Play takes the payment methods of your own country.

Either way

It is one account and one balance, so what you buy on either side works on both. Buy credits on the web and keep using them in the Android app, or the other way round, and nothing is lost if you switch.
