Two products join the CodeEnsis lineup at once, both live on Google Play as of today. iOS is still pending on both — these are Android-first launches.
Heel Drop — a real vibration-analysis instrument, no external hardware
Heel Drop turns a phone's own accelerometer into a live FFT and PSD vibration analyzer. Every spectrum is computed on-device, in real time, from the phone's own sensor — no Bluetooth accelerometer to buy or pair. It's built for the specific job of floor-serviceability checks — structural and civil engineers, architects, and NVH technicians looking at bay slabs, mezzanines, gyms, and rooftop equipment platforms.
Every report includes a free reference comparison against AISC Design Guide 11 walking-excitation limits. That's explicitly a reference for engineering judgment, not a certified compliance calculation — the app reports raw measured data and lets the engineer interpret it, the same as any instrument reading.
Free tier covers live time-domain and FFT view with peak-frequency detection. Pro adds power spectral density analysis, velocity and displacement integration, CSV export, one-tap PDF reports, and unlimited saved sessions. No account, no cloud sync — sessions stay on the device unless exported.
StageMeter — a trip timer that doesn't charge a subscription for basic use
StageMeter is a GPS trip-timer for competitive rally co-drivers: distance and average speed, elapsed-time tracking between time controls, stopwatch-style special-stage timing, and a TSD/Regularity mode with a live ahead/behind-pace deviation readout. Fully offline — it reads GPS directly and never needs a data connection, which matters in the dead zones a rally stage actually runs through.
The actual product bet isn't a new sensor problem — trip-tracking logic like this already exists in CodeEnsis's Odolog mileage tracker, and StageMeter reuses that proven core. The bet is on pricing: the category's established app charges an annual subscription for functionality reviewers describe as "basic," and its own developer has said publicly that limiting the free tier is a deliberate way to monetize heavier users. StageMeter's four modes — Trip meter free forever, Time Control / Special Stage / TSD unlocked with a single one-time purchase — is a direct bet against that model, not an attempt to out-feature the incumbent. Long-press-to-reset (instead of a single accidental tap) and full unit configurability (km, miles, meters, feet, yards; km/h, mph, m/s, ft/s) are both fixes for the two most common complaints on the incumbent's own reviews.
What's next
Both apps are submitted to the App Store; iOS listings will go live once review clears. Until then, both product pages link straight to their Google Play listings:
