Your AWS re:Invent 2026 week, planned to fit.

No. SessionStack is an independent, unofficial planner for AWS re:Invent 2026, not affiliated with or endorsed by Amazon Web Services. It is created by an attendee for attendees. It plans around the same catalogue; it is not a replacement for registering. Seats can be reserved from the app through the official AWS Events API, and what AWS confirms is what you have.

Yes. SessionStack is live on the App Store for iPhone and on Google Play for Android, both free, ahead of the 2026 catalogue going live.

Yes, from version 1.6.0. Connect the AWS Builder ID you registered with under Profile → AWS reservations, and reserve one session or every reservable session in your schedule at once. Each session is reserved on its own, and anything AWS refuses stays planned with the reason. You can also save your schedule or your saved sessions as favorites in the official catalogue. Walk-up sessions are marked as such and need no reservation. Your AWS sign-in stays on your phone and never reaches our server.

The venues are kilometres apart, so the planner walks a route graph between rooms rather than venues. Every search result carries a feasibility badge — comfortable, tight, or not happening — measured against the block before it in your own day, and every booked block carries the walk in front of it.

Yes. Ask in one plain sentence and the AI reads it into those same filters, shown back as chips you can correct or drop. Nothing is hidden between you and the catalogue.

It does not leave the gap blank. It lists the venues actually reachable from your last session and suggests what is worth your time there, ranked against the interests, depth, role and level you gave at sign-up, with a reason on every row.

Every session takes a running note, autosaved, with a device draft when the network is not there, plus a four-field evaluation once the block ends. Those notes and scores become a trip report — actions first — exported as Markdown for whoever paid for the ticket.

Connect with a six-character code and pick one of three sharing levels. A colleague’s day then shows the windows where you are both in the same building.

No. From version 1.3.2 you can use SessionStack as a guest — browse the catalogue, ask in a sentence and build a day — without signing up. The parts that need a server, like colleagues and sync across devices, wait until you have an account. When you do make one, everything you added as a guest comes with you. Sign up with email, or skip the password and continue with Apple or Google.

Thirteen badges across four categories — what you booked before you flew out, the week itself, who you spent it with, and one crown for collecting the rest. Two are secret until you have earned three. They are worked out from the schedule you already have rather than awarded and stored, so nothing needs switching on and nothing needs checking into. From the last day of the event your profile also gets a re:Invent Wrapped: sessions attended, venues explored, time in the room, parties survived, words of notes and badges unlocked. The trip report is the one your employer gets; Wrapped is the one you post.

No. No advertising, no tracking and no third-party profiling in the app, and nothing sold or shared for marketing. From version 1.7.0 it measures how fast screens load, to find the slow parts; that is not linked to your name or account, and you can switch it off in Settings.
