Welcome to this project's final report! This report shares the outcomes, impact and learnings from the grantee's project.

Part 1: The Project[edit]


  • This grant took much longer to complete than expected, due to the codebase overhaul and Covid-19 happening halfway through it.
  • However, we eventually managed to release v3.0 with the full codebase overhaul and new features, and the results were much better than we had even hoped for. We did, indeed, now have a mobile Commons uploader for Android users that was stable, reasonably polished, and easy to upload photos with.
  • The number of images uploaded through our app (especially the number of usable or needed photos) has greatly increased, as has the number of active app installs. Therefore, we believe that most of our goals were accomplished.

Project Goals[edit]

A more stable Commons mobile uploader with a modern codebase, lower code complexity, higher test coverage, and fewer bugs and crashes[edit]

The majority of our efforts throughout the project focused on this goal, and we believe that we have achieved it with room to spare. We overhauled the entire legacy codebase based on modern Android development practices, introduced requirements for test coverage with every major new feature added, and added tests for previous features. These efforts are reflected in our crash rate at the end of the grant (0.45% for the past 30 days as of 19 Jul 2021) and our test coverage (29.7% as of 19 Jul 2021).

Encouraging the upload of high-quality and usable images by mobile users, especially for Wikipedia articles that lack photos[edit]

This is a more subjective goal, but in my opinion it was achieved. 38,119 distinct images uploaded via the app were used in Wikimedia articles as of 19 Jul 2021, and 4,174 places that needed photos had photos added to them via the app as of that date.

An increased number of Commons contributors, especially from the Global South[edit]

This goal was partially achieved (as reflected in our number of active users - 7,182 as of 19 Jul 2021). Our implementation of limited connection mode was successful, allowing easier usage of our app in areas with limited Wi-Fi and mobile data. However, a big part of our plan involved organizing outreach workshops in Global South countries after v3 launch - this plan was unfortunately not able to be carried out due to the Covid-19 pandemic.

Project Impact[edit]

Important: The Wikimedia Foundation is no longer collecting Global Metrics for Project Grants. We are currently updating our pages to remove legacy references, but please ignore any that you encounter until we finish.


  1. In the first column of the table below, please copy and paste the measures you selected to help you evaluate your project's success (see the Project Impact section of your proposal). Please use one row for each measure. If you set a numeric target for the measure, please include the number.
  2. In the second column, describe your project's actual results. If you set a numeric target for the measure, please report numerically in this column. Otherwise, write a brief sentence summarizing your output or outcome for this measure.
  3. In the third column, you have the option to provide further explanation as needed. You may also add additional explanation below this table.
Planned measure of success
(include numeric target, if applicable)
Actual result Explanation
All tasks in project plan completed Completed
Commons app v3.0 released on Google Play Store and F-Droid Completed
Open bug issues on GitHub reduced by 30% from the start of the grant Not completed We realized eventually that this was not a good or realistic metric to have. The main reason is that as the number of app users grow, open bug issues will increase substantially, and many of them cannot be acted on because either the person who opened them did not get back to us with requested information, or we could not reproduce the bug and therefore could not ascertain that our fix solved the problem. We could just close these issues and "make the problem go away", however that would be counterproductive to our goals. Due to this, we believe that crash rate is a much better and more objective indicator of stability, and decided to focus on that.
A crash rate of <1.0% (less than 10 crashes per 1000 devices) in v3.0 Completed. Crash rate on 19 Jul 2021 was 0.45%.
At least 25% code coverage Completed. Code coverage on 19 Jul 2021 was 29.7%.
A total of >20,000 distinct images uploaded via the app are used in Wikimedia articles Completed. No. of distinct images uploaded via the app were used in Wikimedia articles on 19 Jul 2021 was 38,119.
A total of >700 places that need photos will have photos added to them via the app Completed. Total no. of places with photos added to them via the app on 19 Jul 2021 was 4,174.
>50,000 new images uploaded to Commons via the app throughout the grant duration, while maintaining a deletion rate of <10% Completed. Refer to histogram below.
A total of >5,000 active installs on Google Play Completed. No. of active installs on Google Play on 19 Jul 2021 was 7,182.
At least 30 new Commons contributors from Global South countries via workshops Not applicable In-person workshops were cancelled due to Covid-19


Looking back over your whole project, what did you achieve? Tell us the story of your achievements, your results, your outcomes. Focus on inspiring moments, tough challenges, interesting antecdotes or anything that highlights the outcomes of your project. Imagine that you are sharing with a friend about the achievements that matter most to you in your project.

  • This should not be a list of what you did. You will be asked to provide that later in the Methods and Activities section.
  • Consider your original goals as you write your project's story, but don't let them limit you. Your project may have important outcomes you weren't expecting. Please focus on the impact that you believe matters most.

We were extremely stoked about the positive outcomes from rewriting the legacy code! It was something that we had hoped for, of course, knowing the importance of a modern codebase with reduced code complexity, but we did not know just how much of a positive impact it would have on the stability of our app. Our crash rate went from 1.6% to 0.45%, decreasing by 71%. Building new features and debugging issues was significantly easier with a solid foundation, and new pull requests to our repository were much easier to evaluate with a 29.7% code coverage.

There were multiple difficulties that we encountered, starting from everything taking much longer than anticipated, especially rewriting the entire codebase. Also, the Covid-19 pandemic started halfway through our grant, throwing some of our plans in turmoil and causing significant personal hardships for many of our team members. This caused our work to stagnate for a while, and culminated in possibly the longest time taken to complete a grant that I have ever seen.

However, I am immensely proud of my team that we pulled through to completion and delivered a product that we were all proud of. Besides achieving our stability goals, our app has also helped users contribute many photos for places that needed them, and we have increased our userbase significantly. I will let the graphs below speak for themselves:

Total 62,900 USD 62,500 USD 400 USD

Remaining funds[edit]

Do you have any unspent funds from the grant?

Please answer yes or no. If yes, list the amount you did not use and explain why.

  • Yes. We were not able to hold in-person workshops due to Covid-19, so we did not spend the budgeted 400 USD on that. I would like to request that these funds be reallocated to cover salaries for the additional time that it took to complete all the tasks in the grant, as we have put in many unpaid hours to complete it.
Remaining funds are retained by the grantee with WMF's permission until after the report review has been completed and report has been accepted, at which time the WMF program officer will also provide instructions regarding the grantee's reallocation or return of the unspent grant funds.

If you have unspent funds, they must be returned to WMF. Please see the instructions for returning unspent funds and indicate here if this is still in progress, or if this is already completed:


Did you send documentation of all expenses paid with grant funds to grantsadmin(_AT_), according to the guidelines here?

Please answer yes or no. If no, include an explanation.

  • Yes

Confirmation of project status[edit]

Grantee reflection[edit]

We’d love to hear any thoughts you have on what this project has meant to you, or how the experience of being a grantee has gone overall. Is there something that surprised you, or that you particularly enjoyed, or that you’ll do differently going forward as a result of the Project Grant experience? Please share it here!

Overhauling the legacy code took much longer than anticipated, but we have been reaping the rewards for over a year now, and in hindsight I can say that it was one of the most important things we have ever done for the app. Overall, there were ups and downs but the results were better than we had hoped for.
