Frequent Asked Questions

Everything you need to know about [TrinhLabs].
How do I install an app?
These apps are Progressive Web Apps (PWA), so installation is quick and doesn’t require an app store.

📱 On iPhone (iOS)
Open the app in Safari
Tap the Share icon (square with arrow)
Select Add to Home Screen
Confirm → the app now behaves like a normal app

📱 On Android
Open the app in Chrome
Tap the ⋮ menu (three dots)
Select Install App or Add to Home Screen
Confirm the installation

💻 On Desktop (Windows / Mac)
In Chrome or Edge, look for the Install / Download icon in the address bar
If the install button doesn’t appear, you can still bookmark and access it online

📌 Offline use:
Once opened at least once, mobile users can use the apps offline.
A stable connection is only needed for the first load or data syncing (if used).
Are the apps really free?
Yes. All apps are free to use and will remain free for as long as you keep them on your device.

In the future, I may:
Add optional ads to the website (not the apps ❌)
Add optional donations via Ko-Fi
Add support tiers for people who want to help development

But the core experience will remain free.
Help there seems to be data missing?
PWA apps store data locally in your browser storage.
Sometimes devices or browsers clear storage automatically — this depends on the platform:

Device Storage Behavior
📱 iOS (Safari) Can clear app data if storage is low or after inactivity (7-30 days)
📱 Android More stable, but battery/data optimization settings may wipe storage
💻 Desktop Rarely clears automatically unless cookies/cache cleaning is enabled by the user
📌 Private / Incognito mode Not stored permanently, data resets every time the session closes

How to prevent data loss
Keep enough free storage on your device
Avoid clearing browser cache for the site
Don’t use “private/incognito mode” for regular use

Every app includes (or will include)
✔ A Download Data / Backup option
✔ A Re-import feature if data ever resets

This way, you are always in control of your own data.
Where can I follow development updates?
Updates will be shared on:

▶️ YouTube (tutorials, app updates, new features)
✏️ A blog section on the website (written devlogs and version notes)

These channels will launch soon and document the ongoing development.
Why did you decide to make these apps?
I build these apps because they are tools I personally wanted to exist — minimalistic, distraction-free, and enjoyable to use. There’s something special about creating simple products that feel good, respect the user, and don’t lock features behind paywalls.

My goal is to make apps that:
Feel clean and calm to use
Don’t demand your data or time
Respect the user experience
Provide value without pressure

If they help others too, that’s the best possible outcome 😊
