Truly Certifiable, LLC
Apps that tell you the truth.
We make careful apps for iPhone, iPad and Mac. They do their work on your device, collect none of your data, and say so plainly when they don't know something.
Our apps
Slotwise
Scan what you want to hang and print a holder that fits it on an IKEA SKÅDIS pegboard, with the clips worked out for its weight.

Manorly Coming soon
A home inventory for everything you own: purchases, receipts, warranties, maintenance and insurance, kept in sync across your devices and shared with your family.
How we build
Three rules every app follows.
On your device
Scans, backups and AI answers are worked out on your iPhone, iPad or Mac. The only network requests are the ones the job needs, like looking up a card.
No data collected
No accounts, analytics, ads or trackers, in the apps or on this site. The privacy policy covers every app in plain words.
No made-up answers
When a number or a rule can't be known for sure, the app says so instead of guessing.
