LogFai App — BankID time clock app for iPhone and Android
BankID time clock for iPhone and Android
The LogFai app is a free BankID time clock app for iPhone and Android. Staff clock in and out with one tap, approve with BankID and see their shifts and hours. Employers can follow the day in the same app.
The problem
Clocking in on a phone had to be fair to both sides.
Staff wanted to clock in on their own phone instead of queueing at a shared screen. But a phone is easy to fool. Its clock can be changed, a VPN hides the network, and tracking in the background feels like surveillance.
The phone's clock can lie
The time on a phone can be changed in the settings, so it cannot decide when someone started work.
Tracked all day
Background location feels like surveillance to staff, and a time clock does not need it.
A store update for every fix
A regular app needs a new release and a store review for each change, and the review can take days.
A phone left on the table
Phones get lent out and left lying around. Without a lock, anyone could open the app and stamp.
What we built
A BankID time clock app that only knows what it needs.
We built a native app for iPhone and Android with React Native and Expo. It wraps the LogFai web app in a secure shell, so new features reach people without a store update. Sign-in, BankID, location and the app lock run natively on the phone.
Server time, every time
The app only sends the tap. The server sets the time and decides if the stamp counts.
Location only at the stamp
The app reads the location once, at the stamp, and only while it is open. Background location is blocked.
The web app in a native shell
Screens come from the LogFai web app, so a fix can reach everyone the same day. Sign-in tokens stay in the phone's secure storage.
Face ID and a VPN check
The app can be locked with Face ID, Touch ID or a fingerprint. On Android, an employee's stamp is blocked while a VPN is on.
Timeline
From shell to store build in two weeks.
The app grew up next to the web app. The native shell ran on day two, BankID came the day after, and the rest went into what a phone does better and into the store release.
Day 3
BankID on the phone
The app opens the BankID app and comes back after approval. Tested end to end with test BankID on Android.
Days 4–12
Employers and store material
Employer admins in the app, the full logo, the return from BankID on iPhone, and store texts in Swedish and English.
Days 13–16
Store builds
Version 1.0 built for the App Store and Google Play, with screenshots for each phone size and sign-in by personnummer.
The result
One tap to clock in, nothing else to track.
Version 1.0 is built for the App Store and Google Play, with store texts and screenshots ready in Swedish and English. Staff stamp with one tap, and the server still decides the time and whether the stamp counts.
