At J & S Studio, we design and build practical, user-friendly mobile apps for iPhone. From tracking your tiny neighborhood library to decoding vehicle VINs in the field, we build fast, native utilities that just work.
Explore our iOS utilities designed for high performance, ease of use, and native integration.

Manage your neighborhood tiny library or community book exchange effortlessly. Scan barcodes, auto-pull titles, authors, and cover art, and instantly share lists of available books with neighbors.

We develop utilities for Apple iOS devices. Our current app lineup includes My Library Helper (a tiny community book exchange cataloger), Lot Lister (a VIN barcode scanning and vehicle inventory decoder), and ReSeller Receipts (an automated expense scan and cloud manager).
Yes. My Library Helper is designed natively for iOS and is available on the Apple App Store for all compatible iPhone devices.
Privacy is our core priority. Our apps store user records locally on the device (using Apple's native SwiftData framework) and do not harvest personal files or track inventory data off-device.
Lot Lister can be downloaded and used for free with core scanner capabilities. A Premium monthly subscription is available to disable advertisements and remove the export watermarks.
ReSeller Receipts features smart filename templates (e.g. {date} {merchant} {category}) that automatically format and standardize invoice names before uploading them to iCloud, Google Drive, or Microsoft OneDrive accounts.
