Smart training isn’t about doing more — it’s about doing the right work at the right time.
Swirv is built for the way training actually happens: schedules shift, workouts change, and real rides don’t always look like a perfectly checked box. Your week still resolves forward.
Life happens.
Skip a ride, shorten a workout, swap days — Swirv reshapes your week around what you actually did, preserving the intent without the pressure.
Indoor workouts and outdoor rides both matter.
Import from Strava or Apple Health and Swirv uses it to understand your weekly load — so you don’t have “ghost weeks” when you ride outside.
Progression works best when it’s sustainable.
Swirv scales training load with real recovery, keeps intensity purposeful, and helps you build fitness without running yourself into the ground.
Connect Strava or Apple Health to bring in your past rides. Swirv uses this data to understand your current fitness and training load.
Start with an FTP test or let Swirv estimate your FTP from recent rides. This sets your power targets so every interval is scaled for you.
Swirv builds a structured weekly plan based on your fitness, goals, and availability. Each week includes the right mix of steady riding and targeted intensity.
Pair your smart trainer and follow clean, power-based intervals. Swirv controls the resistance so you can focus on the effort, not the settings.
At the end of each week, Swirv reviews what you actually did and reshapes what’s next. Your training evolves with you — automatically.
Your plan flexes when you skip, shift, shorten, or swap rides — so you keep momentum without forcing perfection.
Outdoor rides and indoor workouts both count. Import from Strava or Apple Health so your load reflects real life.
Load builds gradually with real recovery. Intensity stays purposeful so you can train consistently, not constantly exhausted.
Partial workouts and reschedules aren’t a dead end. They become inputs to how your next week is built.
Swirv works with the tools you already use — Zwift, Strava, Garmin and more — so flexibility doesn’t mean starting over.
Effort guidance without judgment. Smooth resistance control so you hit the work and stay in the flow.
Swirv Membership
Free while in private beta.
You're always in control: Swirv never locks you out of the app. You can still open Swirv, view your training history, and export your data, without an active membership.
Swirv began as a personal project in 2024. I wanted an indoor training tool that built fitness sustainably and automatically — without overwhelming my schedule or burning me out.
No virtual worlds. No clutter. Just focused, progressive training built on modern science and thoughtful design.
Today Swirv reflects that vision: a clean, intuitive app built to help real people reach their fitness goals.
Here's to training that goes somewhere — even when your bike doesn't.
— Aaron, Swirv founder
Get early access and the chance to influence what gets built.
Swirv works with most Bluetooth-enabled smart trainers and power meters that follow common standards. If your trainer connects to your iPhone as a Bluetooth power source, there's a good chance Swirv can use it.
Yes. Many athletes run Zwift for visuals and use Swirv to control the trainer and guide intervals. Swirv handles the structure and power targets; you choose the riding environment.
You need a membership to build and follow a training plan, guided interval execution, smart-trainer ERG control, and Strava sync. You can still open the app, view your training history, and export your data, without a membership.
Without a membership, you can install Swirv, connect Apple Health, import your ride history, and run FTP tests. You'll never be locked out of the app or your data.
Swirv looks at your recent training history, weekly load, and completed workouts to build a plan that fits your current fitness. At the end of each week, it updates the upcoming plan based on what you actually did — how much you rode, which sessions you completed, and how your training load is trending.
No. Swirv can support riders who are new to structured training as well as experienced cyclists. The goal is to meet you where you are and build from there, not overload you with intensity from day one.
Yes. Swirv is built around indoor workouts and smart-trainer control, but outdoor rides you import from Strava or Apple Health count toward your weekly load and can influence what the next week looks like.
Swirv is currently built and optimized for iPhone. iPad and other platforms may come later as we continue to develop the product.
Yes. Swirv is in an active beta phase. That means features, training logic, and UI polish will continue to evolve. Feedback from early users is a big part of shaping what comes next.
We'd love to hear from you. The best way to share feedback or report a problem is from within the app or by replying to any email you receive from Swirv. Your input directly influences future improvements.
