Free for our floaters
Check in before your float. Check in after. Watch what actually changes — your stress, your pain, your head — one float at a time.
Free. No account, no sign-up, no ads. Works on iPhone and Android.
What it does
Most people walk out of the tank knowing they feel better, but they can't say how much, or how long it holds. The app is a simple way to find out — and to catch the things that surface while you're in there.
Rate your stress, pain, sleep, and clarity going in — then again coming out. See the change on a single float, and across every float you've taken.
The tank is where ideas show up. Bring a question in with you, then catch whatever surfaced before it fades. Every spark is saved and searchable.
Write down what came up, what let go, what you want to remember. It's yours — private, and stored on your own phone.
Advice for getting more out of every float, that gradually tunes itself to the reasons you float — stress, pain, sleep, or creativity.
Getting it
There's nothing to download from an app store. You open a link and save it to your phone — it then behaves exactly like any other app: its own icon, full screen, and it works without a signal. Take the extra ten seconds to save it — otherwise your entries live in a browser tab you'll lose track of.
On a computer right now? Just bookmark this page and come back on your phone.
Using it
In the lobby, or right before you get in. Tell it why you're floating today, then rate where you're at. If something's on your mind, write it down — the app will ask you about it afterward.
Turn your phone on DND. I hate it when I forget and mine vibrates while I float. Ruins the mood.
Do this before you leave, while it's fresh — you'll be loose and a little foggy, and that's exactly when the good stuff comes out. Rate where you're at now, catch any ideas, and write down whatever you want to keep.
After three or four floats, the trends start telling you something. That's when it gets interesting.
Common questions
Yes. It's free, there's nothing to buy inside it, and there are no ads. We built it because we think it makes floating better.
No. No email, no password, no sign-up. Open it and start.
Nobody but you. Your check-ins and journal entries are stored on your own phone, not on our servers. We can't read them — we never see them at all.
No. The app doesn't send anything anywhere — there's no server behind it. Your ratings, journal entries, and sparks are stored on your phone and nowhere else, and we have no way to see them. If that ever changes, it'll be something you opt into, we'll say so plainly, and your written entries would stay private regardless.
It doesn't need to be. Saving it to your home screen gets you the same thing — an icon, a full-screen app, offline access — without the app stores in the middle. It also means we can improve it whenever we want, instead of waiting on someone's review process.
By itself. When we ship an improvement, your app picks it up the next time you open it with a connection. You'll never have to update anything manually, and your floats and journal entries carry over untouched.
Yes — once it's on your home screen, it runs offline. Handy, because reception in the float rooms is not our strong suit.
Because your entries live on your phone rather than in an account, they don't follow you automatically. Before you switch, open Book → Back up & restore and tap Download backup file. Save that file somewhere (email it to yourself, or drop it in iCloud or Drive). On the new phone, install the app, go to the same screen, and restore it. The app will remind you to back up every few months.
Not even a little. Floating works fine without it. This is for the people who want to see what's happening under the surface.
From the owner
This is new, and it'll get better the more I hear from the people actually using it. If something's broken, confusing, or you wish it did one more thing — say so. There's a Have an idea? button right in the app that'll take you to a short form, or you can use the link below. It takes a minute, and I read every one.
