Questions about app development

Which technology do you use to build apps?

Mostly Flutter, which gives one codebase for Android and iOS. Where an app needs deeper access to the phone, we add native code: our Seen It app combines Flutter with native Kotlin on Android.

Have you published your own apps?

Yes. TripFund, our group travel expense app, is on Google Play, and we also build Seen It and the Super Ledger salesman app. Running our own apps means we deal with store reviews, ads, privacy forms and updates ourselves.

How long does it take to get an app onto Google Play?

Plan for testing as well as building. New personal Google Play developer accounts must run a closed test with at least 12 testers for 14 days in a row before applying for production, and Google says review usually takes up to seven days. Every app we publish goes through a closed test first, and we take it into account when we plan a launch date. Our guide explains Google Play’s 12-testers rule step by step.

Do you handle store listings and privacy policies?

We can help. For our own app TripFund we prepared the store listing, the Data safety form and the privacy policy and terms pages the stores ask for, so we know what is needed and can help you get it ready.
