TANKR vs SideQuest

With the TANKR App, you can rent your favourite sports equipment at Tankr Rentalbase stations. Join the Tankr network and find the rental stations around you quickly - the map shows you the stations located in your area. Live more sustainably without compromising by renting more and owning less. You want to rent sports equipment but there is no-one around to help? No problem, with the TANKR App you have your own key, around the clock. The equipment can be conveniently reserved or booked directly from anywhere.

SideQuest turns free moments into real mini adventures. Choose one of three paths—Safe, Curious, or Wild—and discover details, places, and perspectives that are easy to miss in everyday life. Every quest is editorially created and includes clear guidance about duration, weather, company, mobility, and safety. You decide what feels right today, and you can stop at any time without a penalty. Save completed adventures with a short memory or an optional photo. Weekly Sparks, chapters, and your personal adventure profile reveal which parts of your surroundings you have rediscovered—without daily streaks, leaderboards, or social pressure. All memories and photos stay locally on your device. No account or internet connection is required for the core experience. The first 10 quests are free. After that, unlock the complete library of over 100 quests permanently with a single in-app purchase—no subscription.
