Application calls are a specific type of transaction on Algorand that take place when users or smart contract interact with smart contract, which means that by analyzing some metrics regarding the application call we can better understand the evolution of application usage on Algorand

In this dashboard we will compare metrics about app calls between last 6 months of 2021 and first 6 months of 2022

Let's start by looking at the number of application call transactions by day and by block id in the first months of 2022 ( red bars represent daily app calls , while blue line represents the average of number of app calls over time)

For the chart by block id , I first calculated the number of app calls by each block id but then in order to display numbers on the chart I was forced to select only 1 block id out of 18000 (which is more or leass one a day)

some observations:

• the average is dropping down over time as well as the price of Algorand since January
• avergae of app calls is about 200k per day and 11 per block
• app usage seems quite stable

now let's look at the same metric but for the last months of 2021 this time

observations:

• application usage had been a great spike as we can see from the average:

   app calls transactions went from 10k to 80k a day 
  

What about the number of wallets making those applications calls?

One could easily expect numbers to be similar to the previously analyzed metrics

yes, charts confirm the initial guess since the trends are very similar but there are some notes to be made

• there are some periods in which the wallets making App calls are particularly high ( see January 22 which was due to Vitalpass, and May 22 when there was a huge increase in number of wallets created)

this is because of the fact that there were much more wallets interacting with those apps than other days

Overall we can conclude that there was by far more application usage in first 6 months of 2022 than last 6 months of 2021

This is actually a good signal of health for Algorand blockchain since the price in USD of ALGO was higher in 2021 than 2022 which means that Algorand is doing a great work despide of market conditions

Let's calculate the total SUM of app calls and of unique wallets making app cals in these two periods and compare the results!
