Apple's phased release raises exposure automatically over 7 days, from 1% to 100%, and you can pause it. A Google Play staged rollout stays at the percentage you set until you raise it, and you can halt it. Neither store rolls an installed update back for users.
Definitions
A phased release is Apple's App Store Connect option for automatic updates. A staged rollout is Google Play's way of giving a production update to a chosen share of users. Both exist so that a bad SDK upgrade reaches a small group first. Both pick users at random and neither tells those users they are in the group.
Side by side
| Question | Apple phased release | Google Play staged rollout |
|---|---|---|
| Who sets the percentage? | Apple, on a fixed schedule | You, by hand |
| Schedule | 1%, 2%, 5%, 10%, 20%, 50%, 100% over days 1 to 7 | None, it does not rise automatically |
| Stop it | Pause, for 30 days in total across all pauses | Halt, no limit stated on the page |
| Resume | Continues from the day you paused | Resume, then set a percentage; same users as before |
| Who can still get it | Anyone who downloads manually | Users selected at random |
| Country limits | Not part of the feature | Optional, for production updates only; cannot be removed once started |

What this means for an SDK upgrade
Apple's schedule is hands off, which is good when nobody is watching and bad when you want to hold at 5% for a week. If you want a slower ramp, you pause on day 3 and look at crash data. Remember that the pause budget is 30 days in total, so use it on purpose.
Google's rollout is the reverse. It will sit at 10% forever if you forget it, so put a reminder in the release checklist. Because the percentage only moves when you move it, you control the pace, and a risky SDK change can sit at 5% over a weekend.
On both stores, existing installs of the new version stay installed after a pause or halt. Google states that halting does not roll back. For a real fix you ship a new build.
A simple plan for a small studio
- Ship SDK upgrades alone, not bundled with feature work, so a crash points at one cause.
- Turn on the phased option in App Store Connect for every update.
- Start Play at a low percentage and write the date you will raise it.
- Compare crash free sessions for the new build against the previous build, not against zero.
- Decide the pause or halt trigger in advance, for example a crash rate you will not accept.
Try it yourself
Click through it at your own pace, or open it full screen. Watch how a new finding appears after release without a rebuild, which is the signal that tells you to pause.
Safeguard can scan your dependencies and produce an SBOM for each mobile build, so you know which SDK versions are in the 1% group. A free scan is available.
Quick check
Can I speed up an Apple phased release?
Yes. Once the version is Ready for Distribution you can choose Release to All Users at any time.
Does a Play halt remove the update from people who have it?
No. Users who already have the version keep it. Ship a fixed build to replace it.
