HOLDOVER SOFTWARE

Independent App Studio

Small apps that do one thing properly.

A one-person studio building focused, offline-first apps for iOS. Every app runs its work on your device, keeps your data local, and asks for no account. Two so far: one for precision shooters, one for small kids.

Holdover Software is a studio of CM Collective LLC.

Different people, different problems, same standard.

How we build

The same three rules apply whether the user is a competitor at 800 yards or a three-year-old.

On your device

Calculations and saved data stay on the phone. No accounts, no sign-in, and nothing to lose when the signal drops.

Nothing collected

No third-party analytics, no tracking, no advertising SDKs in any app we ship. There is no data pipeline behind these apps because we did not build one.

Built for the real setting

A drop table gets read in direct sun, one-handed. A kids app gets used by someone who cannot read yet. Both get designed for that, not for a demo.
