Do you have Google sheets and Google Forms?

You can make easy quizzes with those.

thank you for the reply sir…
to answer your question, i want a multiple choice quiz wherein users need to connect to internet…my purpose is that i want them to have internet so that my ads will appear while using my app…of course i will include some elementa there like score, high scores, and show the missed questions with corresponding correct answers…
the link of tutorial that i read is below

sounds interesting…does this google sheets and forms help me create online quiz???
if so, i need help to learn about this…

thanks for the reply again sir…i already followed and created a quiz using the guidelines or tutorial from the link you provided…but my problem with this is that it is offline…i want it to be online …i have some idea about how to do it like using tiny web db…but i have problem with web service which is part of the process to create an online quiz…following the procedure which is stated on the post that i linked , i stopped early in the procedure where i need to create a web service…it requires payment .so i posted here to know alternative web service that is free or is there any other way to create an online quiz aside using web service…
sorry for my grammar…btw
hope you understand what i am trying to communicate…

What was the web service you tried?

sir i have not tried it yet because i need to give credit card details which i dont have…the tutorial called it app engine for python 2…im here to search for alternative method, that require no payment if possible…

You could try:

AsteroidDB Extension

which is free for up to 10,000 records

or if you have your own hosted php server you can setup your own tinywebdb:

Your Own Secure php TinyWebDB


sir i already tried it and it seems like im in the middle of the process…i think i am done with storing my data using asteroidb .but i have problems with how i am going to retrieve tglhe data…i create a separate app to retrieve the data using a get value block of asteroidDB…but when o tried to open the app for testing…it doesnt load my data…

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.

well, do you want to use AsteroidDB or TinyWebDB?
a mixture of both will not work…

Did you setup your AsteroidDB instance? AsteroidDB is just a Python app which needs to be installed an cloud application service.

i dont know what instance means…but what i did only is i create an account with heroku web service…then create an app…i used the url provided by heroku to store my data…sorry for my ignorance for i am a newbie to appinventor…actually im not a programmer or developer…but i already learned how to create some apps with appinventor…did i miss some step??

Maybe Robert…the documentation for that database is very basic and there is no example tutorial showing how to build and use the database.

Since it is a cloned copy of a TinyWebDB, I would find a tutorial showing how to use the TinyWebDB and substitute the equivalent controls using asteroid. You might start with the TinyWebDB example
here Chapter 22. Databases under the heading Shared Data and TinyWebDB That might get you started on the right track.

sir this is the block which i used to store my data…then i created a separate app to retrieve the data but i cant retrieve it using the blocks that i previously attached in this thread…
