Measure what actually happens in a gym.
A small number of tools for physical education teachers and teacher education programs. Each one does a single job, records real data, and hands it back in a form a school can use.
Four tools, each with a job.
ClassMetrics HR
iPadLive heart-rate monitoring for a whole class on one iPad. Standard Bluetooth chest and wrist straps stream to on-screen zone colors in real time, and a session turns into a defensible record of time spent in moderate to vigorous activity — synced to a teacher's own account when they sign in, private on the iPad otherwise.
- Live zone view
- MVPA totals
- Roster import
- CSV export
CoachSAGE
iPhone and iPadA frame-accurate video analysis app for coaches and PE teachers, built as a successor to Coach's Eye. Step through a clip one frame at a time, slow it down, draw on the movement, and put two attempts side by side. An athlete can also record a self-check and ask for feedback on specific still frames, without the clip ever leaving the device.
- Frame-accurate scrubbing
- Telestration
- Side by side
- AI self-check
Basal
iPhoneAn adaptive macro tracker. Describe a meal in plain language and AI turns it into calories and macros — everything after that, your targets, your estimated burn, your weekly correction, is deterministic math that compares its own prediction against your actual weight trend and adjusts itself, rather than a fixed formula you outgrow.
- Plain-language logging
- Adaptive targets
- Apple Health
FieldTracker
WebField experience management for teacher education programs. Placements, hour logs, supervisor sign-off and accreditation reporting in one place.
- Three roles
- Rubric assessment
- Canvas integration
- CSV export
How these are built.
Process, not just outcomes
A fitness score says what a student can do. Time in a heart-rate zone says what they actually did in your lesson. The second one is the part that tells you whether the teaching worked, and it is the harder one to collect, so that is where these tools start.
As little as the job needs
Video stays on the device it was recorded on. Class data stays on the iPad unless a teacher signs in to sync it. There are no analytics libraries and no advertising identifiers in any of these apps, because student data is not ours to collect.
Built in real classes
These are written by a physical education teacher educator and used in real gyms and real placements: noisy, fast, and short on prep time. A tool that needs ten minutes of setup before class does not get used twice.
Every video and every heart-rate reading is written where it is recorded first. Nothing syncs off a device unless a teacher signs in to ask for that.

One person reads that inbox and normally replies within two business days. During the school year it can take a little longer.
- Which tool you are asking about
- Your role, and roughly how many teachers or students are involved
- Whether your district needs a data agreement or a security review first
- For a bug report: the device, what you did, and what happened instead
