Psychology & the room
“Download our app to continue” is where you lose people.
An install used to be the price of a good tool. Now it's a barrier: a security review to pass, a permission to grant, a moment for the user to reconsider. When the browser can already do the job, asking for a download is asking a lot.

Think about the last time a screen said "install our app to join." On your own device it's mildly annoying; on a client's locked-down laptop it's a full stop — no admin rights, no approval, no chance. The install isn't a neutral step. It's a gate, and a lot of people (and machines) can't or won't pass it.
✕ The myth
"Serious tools have you install an app."
A real product ships software; web apps are the lightweight option.
✓ The reality
Install is friction, risk and delay.
Every download is a security review to pass, an admin right to have, and a moment to abandon — while the browser already ships what presenting needs.1
The reason "zero-install" has become an expectation is that it's now possible: the capabilities presenting requires — document rendering, encrypted peer-to-peer networking, graphics — are standardised, in-browser, on every device.1 Security best practice, meanwhile, pushes toward least footprint: fewer installed agents, less standing software to trust and patch.2 Not installing is both easier and safer.
Friction is the enemy of adoption
The tool that gets used is the one that's usable right now, by everyone in the room, on whatever device is nearest. An install narrows that to "people who can and will download it," which in a mixed room of clients, guests and locked machines is a small and unpredictable set. Zero-install keeps the door open to everyone — including the client's PC that would never approve a new program.
Review
Corporate installs need IT approval you rarely have on the day.
Abandon
Every extra step is a chance for the user to give up.
Footprint
Fewer installed agents = less to trust, patch and breach.

⚖ The honest bit — native still earns its place
"Zero-install" is a default, not a dogma.
Let's be balanced. Plenty of software genuinely deserves an install: deep OS integration, offline-first workflows, heavy pro tools, low-level hardware access, or performance the browser can't match. For those, a native app is the right answer and "web-only" would be a downgrade. The claim is scoped to lightweight, shared, come-as-you-are tasks — like getting slides onto a screen — where an install buys nothing and costs reach. Default to zero-install; reach for native when the job actually requires it.
Where SyncBy!App fits
SyncBy is zero-install on purpose: open a web page on the screen, open one on your phone, present. Nothing to download on either side, nothing for a client's IT to vet, no one left out because they couldn't install it. When your task genuinely needs a native application, use one without apology — but for wireless slides, asking anyone to download something is exactly the friction we removed.
TL;DR
- Installs are friction: security review, admin rights, abandonment — and a hard stop on locked machines.
- Presenting's needs are standardised in the browser, so zero-install is now feasible.1
- Least software footprint is also the safer posture.2
- Honest caveat: native still wins for deep OS work and heavy tools — default to web, reach for native when needed.
