Do you need a stream deck?
Before you spend on hardware, your iPhone can already be the deck — and do things a button box can't, like mixing your audio.
You don't necessarily need to buy a Stream Deck. A free software deck on your iPhone covers OBS scenes, audio and macros without spending anything. Hardware is worth it mainly for tactile keys and physical dials; if you don't need those, an app like SIDeck Studio does the job — and adds a per-app audio mixer most hardware can't.
When a hardware Stream Deck is worth it
Let's be honest: hardware genuinely wins in places an app can't. A physical Stream Deck gives you tactile keys you can hit blind, mid-action, without looking down at a screen — that muscle memory is real, and after a few weeks your fingers just know where each scene lives.
If you want physical dials, the Stream Deck + adds rotary knobs for things like volume and exposure that feel better than any on-screen slider. Dedicated hardware also frees your phone for other use, stays reliably connected, and — if you're already invested in the Elgato plugin ecosystem — drops into a workflow you know. For some streamers, that tactile certainty is worth paying for.
When a free app is enough
For most streamers, the day-to-day work is switching OBS scenes, toggling a source, muting the mic, and firing a few macros or chat actions. A software deck on a phone you already own does all of that — and a free tier means you can set it up and stream tonight without spending anything.
SIDeck Studio's free tier includes two audio channels, up to six macros, one Custom Mode, OBS scene and source control, and pairing over your local Wi-Fi by scanning a QR code. No hardware, no credit card. If you outgrow it, Pro is $4.99/month with a 7-day trial — but plenty of streamers never need to.
The thing hardware can't do
Here's the part that flips the question. Because SIDeck talks to a desktop host on your Mac or Windows PC, your phone reaches things a button box physically can't — starting with your audio.
- Per-app audio mixing, from your phone — set your game, Discord and music to independent levels on Windows and Mac, instead of one master volume.
- Push-to-talk and push-to-mute your mic — hold to talk or tap to mute mid-stream, without alt-tabbing to a mixer.
- Remote macros over the internet (Pro) — fire a macro on your home PC even when you're away from your LAN, through a secure relay with no port-forwarding.
Frequently asked questions
Do I need a Stream Deck to stream?+
No. A Stream Deck is a convenience, not a requirement. Software decks cover the basics — OBS scene switching, audio control, macros and chat actions — for free from a phone, so you can start streaming without buying any hardware.
Is a Stream Deck worth it?+
It depends on you. A hardware Stream Deck is worth it if you value tactile keys you can hit blind and physical dials, or you're invested in the Elgato plugin ecosystem. If you don't specifically need those, a free phone app does the same control without the spend.
What's a good free Stream Deck alternative?+
SIDeck Studio is a free software stream deck for iPhone and iPad. It controls OBS scenes and sources, a per-app audio mixer, and macros from one app, with no hardware required and no credit card to start.
Can a phone app replace a hardware Stream Deck?+
For most streamers, yes — a phone app handles OBS, audio and macros just as well, and adds per-app mixing hardware can't. The exception is where you specifically want physical keys and dials you can operate by feel; that tactile control is the one thing a screen can't replace.
