Mobile-first design

Mobile responsive, no app required.

A manager is on a client site and an employee needs a leave approval - but it has to wait until tomorrow. Synthro is mobile-first: approve leave from your phone, check goals from a tablet, full functionality in the browser on any device, no installation needed.

The problem

HR stuck at a desk. Employees waiting on approvals.

HR stuck at the desk

A manager is travelling and an employee emails "please approve my leave". They cannot approve from their phone and must wait for a desktop - leave delayed three days. Synthro works on the phone: open the browser, approve, done in 30 seconds.

No app-store downloads required

Other systems make you download a 200MB app and create a separate login. Synthro opens in any browser on any device with the same login as desktop - no downloads, no separate accounts.

Employees cannot access on phones

Sarah needs to check her leave balance on a Saturday, but a desktop-only system is unusable on a phone - broken UI, tiny buttons. Synthro is designed for phones: large touch targets, readable text, smooth scrolling.

Approvals delayed by location

You are in a client meeting and five leave requests pile up that you cannot approve from your phone. With Synthro mobile you clear all five during a break - swipe, tap approve, done.

Works offline as a PWA

A remote site has bad signal and a desktop app keeps disconnecting and losing work. Synthro is a Progressive Web App - it works offline, caches your data, and syncs when you are back online.

The same experience on every device

Some tools show a limited mobile view with missing features. Synthro gives you every feature on every device - create goals on a phone, approve reviews on a tablet, export data on a laptop.
