OatStock tracks your pouch stash, logs every shake with one tap, and predicts when you'll run low — so you reorder right on time, never in a panic.
From the daily one-tap log to the analytics that tell you when to reorder — OatStock turns "do I still have any Mocha Dream?" into a glance.
Tap once to log a shake — instant, with a little haptic buzz. Forgot yesterday's? Backdate it in seconds.
OatStock learns your per-flavor pace, projects when each runs out, and builds a paste-ready shopping list.
Flavors flag themselves before they hit zero, so the reorder never sneaks up on you.
Trends across 7, 30, 90 and 365 days, flavor popularity, streaks, and your projected yearly intake.
Pin the flavors you actually drink so they bubble to the top of every list and suggestion.
Full CSV export whenever you want it. Free forever — no ads, no tracking, no lock-in.
Pick from all 25 Oats Overnight flavors and set how many of each you have on the shelf.
A single tap logs the shake and updates your stock in real time.
OatStock predicts run-out dates and hands you a ready-to-paste shopping list.

No. OatStock is an independent, unofficial companion app for fans. It is not affiliated with, sponsored by, or endorsed by Oats Overnight — all product names belong to their respective owners.
It is completely free, with no ads and no tracking. If it saves you from a panic reorder and you'd like to chip in, sponsoring development is entirely optional and unlocks nothing.
iPhone at launch. Android is planned — the codebase is cross-platform, it just isn't shipping in v1.
On the hosted backend by default, or entirely on your own server if you self-host. You can export everything as CSV and delete your account at any time.
OatStock is heading to the App Store. Grab it the moment it lands — and reorder on your terms from day one.
