A look inside
Designed like a kitchen notebook
Ruled paper, masking tape, and rubber stamps. Warm, clean, and quiet, without cluttered spreadsheets.
What Stoku does
Everything you buy on repeat, always under control
Add an item once, set how often you buy it, and let Stoku keep count.
Home Screen Widgets
See what needs restocking right on your iOS or Android home screen. Pre-computed offline timelines stay accurate even when the app remains closed.
Shopping List & PDF Print
Low-stock items automatically appear as shopping suggestions. Ticking an item marks it bought and resets the timer, or you can print a clean A4 PDF for store trips.
Quick Add & Update Mode
Batch-add a full shelf of items in seconds by category, or use Update Mode on the home screen to check off multiple restocked items with one tap.
Clear Status at a Glance
Items sort automatically into Overdue, Due Soon, and Stocked based on your custom day, week, or month intervals and a smart 30% threshold.
100% Offline & Private
All your items and notes stay in a local SQLite database on your device. Zero tracking, zero cloud servers, and easy manual JSON backup export.
4 Built-in Languages
Fully translated into English, Indonesian, Japanese, and Korean, with automatic device language detection and an in-app language switcher.
How it works
Three simple steps
Stoku is an automated counter, not a daily chore. You only touch it when setting up an item or marking it bought.
- 01
Add what you buy on repeat
Pick from the starter catalogue or add your own staples (milk, coffee, laundry detergent, pet food).
- 02
Set the buy interval
Enter a schedule (every 7 days, 3 weeks, or 2 months). You can fine-tune it anytime.
- 03
Mark it bought
When you restock, check off the item. The counter resets back to stocked automatically.

Frequently Asked Questions
Common questions
Does Stoku need an account or an internet connection?
No. There is no account sign-up and no cloud server. Stoku stores everything in a local database on your phone and works fully offline.
How does Stoku know when items are running low?
You set your typical restock interval (in days, weeks, or months). Stoku counts forward from your last purchase date, marking items as Due Soon when they enter the final 30% of their cycle, and Overdue when past due.
How do the home screen widgets stay updated offline?
Stoku calculates and stores a 30-day timeline of daily snapshots locally on your device. Your widgets update smoothly each day even if you do not open the app.
How do I backup or transfer my data?
In Settings, tap Export to save a complete JSON backup file via your device share sheet (save to Files, Google Drive, iCloud, or send to yourself). You can restore it anytime on a new device.
What are the pricing options?
Stoku includes a 3-day full-featured free trial on install. After the trial, you can unlock lifetime access with a single one-time purchase, or choose a flexible monthly or yearly plan.
