A FEW SIMPLE STEPS
Have your phone connected to the internet before you start.
On your iPhone, open Safari and visit the jewellery app address below. If you arrived from WhatsApp or another app, open the link in Safari first.
Use Safari’s Share button (the square with an upward arrow). In the compact toolbar, first open More, then Share.
Choose Add to Home Screen. If Open as Web App is shown, switch it on, then tap Add. You can keep the name GemTracksy.
Return to your Home Screen and tap GemTracksy. Sign in with your existing MyTracksy account, or create an account if this is your first visit. Complete setup while connected to the internet.
Browser labels can vary by version. See the official instructions from Apple: add a website to your Home Screen (opens in a new tab).
BEFORE YOUR FIRST GEM-TRADE DAY
Install and sign in on your chosen device before entering gem-trade information.
Free and Pro use this same app. Lots, buy/sell trades and cash notes stay on this device first. Check that the latest entries are visible before relying on a record on another device.
Gem money uses the signed-in ledger. Closing a sale may write income when you are signed in. Clearing website data can remove unsynced device records.
After an online setup, saved screens and local records may open offline. New sign-ins, the signed-in ledger and subscription changes need an internet connection.
Before changing devices or removing stored app data, sign in on the new device and confirm your latest entries are present. Read the storage and privacy guidance.
NEED A HAND?
Open the address directly in Safari on iPhone or Chrome on Android. Leave private browsing and any WhatsApp or social app browser, let the page finish loading, then check the browser menu again. On iPhone, use Edit Actions in the Share menu if Add to Home Screen is missing.
On iPhone, check that Open as Web App is enabled when adding the icon, if your version shows that option. On Android, choose Install when offered. A shortcut may open a browser tab. You can still use the website there; do not clear website data to troubleshoot.
The installed app may use a separate browser session. Connect to the internet and sign in with the same account; your signed-in gem money follows your account.
Check the email address of the signed-in account and reconnect. Pro access follows the account with that entitlement. Device-first entries stay on the device where you typed them.
Open the app while connected to the internet. Save your work before closing and reopening it. Updates are delivered through the website; you do not need an app-store download. Avoid clearing app data as an update step.
YOUR FIRST-OPEN CHECK
Confirm these on your phone after installation.
This is your checklist, not an automatic device test. Ticks reset when you reload this page.
