We make iPhone apps that get you moving.
Hydro Studio is an independent app studio. We design, build and run our own apps, start to finish.
We build our own products, start to finish.
Each app starts with one everyday problem. We build it natively for iPhone, ship it, and keep improving it long after launch.
Made for iPhone
Built natively in SwiftUI, using the Lock Screen, Dynamic Island and widgets where they help.
Private by default
Locked In keeps health entries on your phone. Cruise deletes live locations when a drive ends.
One job each
Locked In helps you finish the plan you made. Cruise keeps a group of friends driving together.
Locked In
Plan tomorrow tonight. Then show up for it.
An accountability app for people who know what they want to do and keep putting it off. Plan your day the night before, start each task with one tap, and earn XP only for the time you actually put in.
- Nightly planning
- Lay out tomorrow and approve it before midnight. A day with no plan costs you.
- Focus sessions
- One tap starts the timer, and it follows you to the Lock Screen and Dynamic Island.
- Plead your case
- Can't make a task? Pick your reason and get a fair verdict: a protected streak, a new time, or a challenge.
- Your proof
- Levels, streaks and goal cards, all built from sessions you actually finished.
Coming soon to the App Store

Cruise
Drive together, not just to the same place.
A group drive app for 2 to 8 friends. Meet up, pick one destination and follow it on a shared live map. Stay close as a pack to score. Fall behind and Cruise tells you to catch up.
- One live map
- Every driver on the route, with their speed and who is ahead or behind.
- Formation scoring
- Points for staying within a quarter mile of the pack, measured along the road.
- Nearby voice
- Talk with the drivers around you. Nothing is recorded.
- Crews and ranks
- Drive with your crew and earn XP from Rookie up to Cruise Legend.
