Hot take:
Your analytics tool doesn't need session replay, 47 tracking scripts, or a surveillance van parked outside your users' house.
But it can have a cute mascot.

Developers install betas early. Which means app analytics can sometimes spot the future.
TelemetryDeck is already tracking #iOS27 activity. Last year, our #iOS26 adoption charts became a popular reference.
The first iOS 27 numbers are now live: telemetrydeck.com/ios27

One of our favorite annual traditions is finding the next iOS version before Apple tells everyone about it.
We've started seeing the first #iOS27 devices in TelemetryDeck data. 📈
The numbers are tiny for now, but every major rollout starts somewhere: telemetrydeck.com/ios27

App developers spend all day thinking about user experience. Then we open our analytics tools and stare into a gray spreadsheet abyss. We wanted to fix that.

We have some users in @FitWoody_Camp that are so early adopters that they've already installed #iOS27 👀

Apple hasn't announced #iOS27 yet. But we're already seeing it in the wild: telemetrydeck.com/ios27
TelemetryDeck has detected the first iOS 27 devices across our network of 10,000 apps and 10M monthly active users.

Check it out, maybe sign up for some community events if you're around for #WWDC26!
A huge thanks to both @rocketsim_app & @Telemetry_Deck for helping make this possible. This is for the community, by the community!
See you all in Cupertino! 👀

Analytics dashboards all start to look the same after a while. That's why we gave our mascot, Sondrine, an actual personality.
Turns out a tiny blob of joy can make retention charts feel a lot less like tax documents.

This dev team had a classic app development problem:
Week 1 retention: “This app will change my life 🚀”
Week 2 retention: absolute silence
With analytics, they found out where motivation dropped off and improved...
👉 onboarding
👉 reminders
👉 rewards

Developer marketing 2026:
Our ICP still discovers tools through recommendations. But they now come from Claude and ChatGPT instead of Twitter threads.
For TelemetryDeck, Claude alone now drives 46% of reported new signups.

#PowerKids helps kids build healthier habits and chose TelemetryDeck because they needed analytics without compromising health data or user trust.
No creepiness or PII. Just the insights needed to improve retention and help families better.

Tech update: You can no longer invite yourself to your own organization, because this creates a space-time paradox where multiple branching dimensions pop up in the quantum realm. Also, inviting yourself would demote yourself from admin to user, which is not the intended effect.

One of the biggest TelemetryDeck projects this spring was completely invisible to almost everyone: We migrated our entire infrastructure to @Hetzner_Online without data loss and apparently without causing enough chaos for people to notice. 😅

Apple requires you to declare if your app is a regulated medical device. Applies if your app is in #Health & #Fitness or #Medical or includes medical content.
Do:
• Set the status in ASC
• Add regulatory info
When:
• New apps: now
• Existing: 2027
