OpenLitterMap is an open source, interactive, and accessible database of the world's litter and plastic pollution. Just take a photo and tag it with our app. Litter is the first application of this real-time data collection platform. For the last 8+ years we have been crowdsourcing data to help train the OpenLitterAI to help with detection and classification. You can extend our pre-defined list of tags with your own custom tags. Just type in whatever you want and press enter. Keep the global map open to see live updates. If you click on a notification, you will be zoomed to the data that was just recorded. Copy the URL to get a link that can send anyone to any photo. Our code & data is open and accessible. Anyone can download our data for free, and use it for any purpose. This is necessary to bring transparency and democracy to science on pollution. As you tag litter, you help your country compete at the #LitterWorldCup to see who can collect the most data. By default, all users are anonymous. However, you can make your name or username appear on the map or leaderboards and compete for a position. You can also add your social media links which will appear on each upload. Like getting upvoted, the more data you upload means the more visibility you will get! Follow us on social media to keep up to date with all of the latest updates and developments.

Verdict
The clearest difference is review sentiment: OpenLitterMap at 83% against OnCampus's 36%. OpenLitterMap also leads on update cadence (every 3 weeks vs every 6 weeks) and iOS requirement (15.0 vs 18.0). OnCampus's advantage is rating (4.8 vs 3.6) and ads (none vs shown). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
OnCampus holds the better App Store score, 4.8 against 3.6. Both are backed by a comparable volume of ratings — 43 and 9 respectively.

OnCampus ships an update every 6 weeks, OpenLitterMap every 3 weeks. The most recent releases landed on September 30, 2026 and September 26, 2026 respectively.
