Why runtime costs after 2 years?

Citizen Science apps need constant updates and care.

In an ever changing online environment, it is essential especially for smartphone apps to stay constantly updated and adopt to changing standards or technologies. Since online citizen science projects are per definition interactive user-oriented applications, it is important to provide ongoing maintenance to the software they run on for stability, safety and also compatibility over a longer period of time.

Life cycles of online software and especially smartphone apps are very short. To prevent your apps from becoming unuseable on new operating system versions, get clunky or functionalities simply get broken by time, we have chosen to offer SPOTTERON as a Software as Service (SAS) model, so we can take care of all projects on the platform during their whole runtime while also being able to keep prices low.



SPOTTERON Citizen Science provides monthly updates

We always keep your smartphone apps updated.

Every project on the SPOTTERON platform receives regular updates with improvements, patches and even new advanced features and extensions.

monthly security

We provide constant stability & safety.

The life cycle of smartphones and their operating systems is very short and changes need to be made to all apps constantly for stability and security reasons.

monthly lowcosts

It ensures low costs by distributing efforts

Being able to provide regular patches because of our subscription model means one app does not have to pay for already existing features on the platform.

monthly techupdates

We automatically take care of new standards

Technical, design or law standards can change during the runtime. We automatically take care of those changes without additional fees.


Software as Service (SAS) or subscription based services are a growing standard, since they ensure a hassle free service for the partner without additional costs coming up during runtime because of neccessary adaptations. In addition, it enables us to run all your Citizen Science apps and projects without user tracking for ad profile building or third party ad networks.

Graph of Citizen Science App Updates on the SPOTTERON CitSci Platform

On average, we provide around one update per month for all Citizen Science apps running on the SPOTTERON platform. Minor updates (displayed in gray) include improvements and bugfixes for the apps, while major updates (in color) also bring new features to all apps. Milestone releases (1.0 and 2.0) are major steps in the development and mark new main versions of SPOTTERON.



We have established a routine called the “extended runtime” to be able to keep your project alive even after the official runtime is over. After the subscription period ends, we automatically provide a 4 weeks free cooldown period in which all 4 parts of a project - Android app, IOS app, interactive map and administration interface - still continue to run normally.

After the cooldown period, we can keep the interactive map, in which all project users are able participate and submit data, and your administration interface access online for a small monthly fee of € 50,- (Package L; excl. VAT if appliable) for unlimited data hosting, web-app updates and support.

Citizen Science App Life Cycle on the SPOTTERON Platform

During the extended runtime, we still keep your project ad-free and without user monetizing or third party ad profile tracking.



  • New in our blog series: the Tea Bag Index (TBI) collects data on soil observations and in particular on the dynamics of soil decomposition. The degradation of organic matter in the soil is part of the global carbon cycle, which provides information about the biological activity of the soil and is therefore important for climate change.
