ARBH Labs builds on-device software for medication history and personal heart and breathing-rate estimates. Your records stay close at hand, on your phone.
PulseTracePersonal biosignal estimates
A record of your routine. A window into your signals. Use them separately, or bring your PulseTrace readings into LastDose.
01 / Medication & vital records
When was the last time? Keep medication logs, elapsed timers, and vital records together in one place. A clear timeline for the details that are easy to forget.
02 / Personal biosignal measurements
Explore heart and breathing rate estimates using your phone’s cameras and microphone. Processing happens on your device, and readings can be saved to your LastDose record.
The technology should do the hard work. Our focus is on making capable, personal software feel straightforward to use.
Meet ARBH Labs ↗Our in-house sensing technology uses the cameras and microphone already in your Android phone to estimate pulse and breathing rate.
PulseTrace processes signals on your device. LastDose keeps your records locally, with encrypted backup and sharing options when you need them.
Bring PulseTrace readings into LastDose to keep observations alongside your medication timeline. Each app also works on its own.
Built for personal tracking and wellness. PulseTrace estimates depend on your device and measurement conditions. Neither app is a medical device or a substitute for professional care.
