SwipeCaddy
Knows which card in your wallet earns the most at every store — cash back, points, or miles. Private and on-device, no bank logins.
How we build
A small team, shipping for the long run.
We keep the company small on purpose, so every app we release is one we can still support years later.
Small by design
One team, six apps. We keep the surface area tight so nothing we ship gets abandoned.
Private where it counts
Several of our apps are built to avoid your data entirely — NxtTools processes files on your device, and SwipeCaddy works without a bank login or card numbers.
We run what we build
Nothing here is handed off at launch. We keep each app updated, supported, and online ourselves.
FAQ
Frequently asked questions
Do you take on client or contract work?
No. Const Agility builds and runs its own products. We are not a consultancy or an agency, and we do not take on outside projects.
What do you make?
Six apps today: Faxify for sending and receiving fax, Roletopia for AI interactive stories, NxtTools for on-device file and QR utilities, QRly for QR bundles (in development), iPlay for free browser games, and SwipeCaddy for picking the credit card that earns the most.
How do I get support for one of your apps?
Each app has its own website and support channel, so start there — every product on this page links straight to it. For anything else, email [email protected].
Do your apps collect my personal data?
It depends on the app, and each one publishes its own privacy policy. Several are built to avoid it: NxtTools processes your files on your device, and SwipeCaddy never asks for a bank login or card numbers.
Where are you based?
Texas, USA. Const Agility, LLC is a United States company; our postal address and phone number are in the footer.
Can I suggest a feature or report a bug?
Yes, please. Use the support link on the app's own site, or email [email protected] and it will reach the team.
