How apps are reviewed and scored

Blockstack uses third-party reviewers who interact with, review and provide scores for the apps in the App Mining program. The scores from each reviewer are used to determine an app`s ultimate rank. In this section, you learn more about the reviewers and how they score.

TryMyUI

TryMyUI provides 1.5M application testers around the globe, and apps enrolled in app mining are reviewed by 10 users every other month and rated on the following dimensions:

  • Usability
  • Usefulness
  • Credibility
  • Desirability

TryMyUI drops the highest and lowest test scores and uses the middle 8 scores each month for the rankings and calculates and average of scores for each component. Apps that are not being tested will receive the same scores as the last test round. TryMyUI has it’s own “history” component to increase reliability of the tests. On average, projects need around 20 user tests to get actionable and reliable feedback. TryMyUI provides a monthly score that reflects 75% of the new month’s score, and 25% from last month’s score. The calculation to find that is:

X = raw score of new month
Y = final (rolled) score from previous month

0.75X + 0.25Y = new month’s final score

TryMyUI tests occur from the beginning to middle of the month, and Blockstack PBC cannot provide exact timing of the tests. App founders should not make any breaking changes to the app during this time. TryMyUI testers are English speaking. TryMyUI provides niche audiences based on the type of app. Founders can take this brief survey to fill out their preferred audiences.

New Internet Labs

New Internet Labs ranks apps based on their use of Blockstack Authentication (Auth) and Gaia as a measure of Digital Rights. New Internet Labs may test on any browser or device of their choosing for web apps. If the application is a mobile app, then it is tested on the appropriate mobile OS.

For authentication, the scoring criteria follows:

Rating Blockstack Auth
4 Is the only authentication method.
3 Is the primary authentication method.
2 Is one of many authentication methods.
1 Is of secondary importance among many authentication methods.
0 Is not used at all.
-1 Is not used at all.

For Gaia, the scoring criteria follows:

Rating Gaia
1 Is used.
0 Is not used or the reviewer could not determine.
-1 Is used but is broken.

New Internet Labs provides these raw scores to Blockstack. Apps that are found ineligible by New Internet Labs due to having an error in Auth are disqualified from app mining.

Awario

Awario provides data about app awareness by scanning the web for ‘Mentions’ of the app name. The Awario score for App Mining is a result of measuring the Reach of these Mentions (specifically, Blog/News mentions), combined with the growth rate of overall Reach, combine with a binary examination of Mentions on social media.

Awario rankings start counting at the start of the month the app was submitted, and the results are incorporated into the rankings the month following. This means that any data used in calculations is from the previous month. New apps to the program do not incorporate this score on their first month of being enrolled.

As of October 2019, Awario ranks apps based on Blended Awareness which is comprised of these parts:

  • A binary scoring on social networks, that is, you get a number out of 5 max (1 point for any Mention registered on Facebook, Twitter, YouTube, Reddit, or Instagram).
  • A reach score for any mentions in the news or blog section. The reach will have log10 scoring applied to it.
  • A growth score which is calculated the same way, just limited to the growth in reach from the news or blog mentions.

Each of these three pieces will make up 1/3 of your overall Awario score. Some special conditions to understand about these values:

  • The first month you have Awario data you won’t receive a growth score. This means your score for the first month is only comprised of reach and social.
  • If your reach in the last month was less than 1000, you don’t get a growth score. This is designed to prevent huge growth percentage outliers.
Note: During the transition to the new Awario scoring method, no app will have a growth score in the first month.

Blockstack publishes the Awario data sheet with all app mentions for auditing at the start of the audit period. Blockstack PBC employee social media accounts are omitted from the reach scores. There is also a manual scan of Awario data to remove any data suspected of a false match.
