Engineered for Confidence
Why LastDose is worth using.
Medicine tracking without ad tracking, cloud subscription traps, or confusing interfaces.
The FrictionDid you already take it?
Accidental double-dosing and missed doses happen when daily routines blur. Conventional alarm apps just get swiped away.
The SolutionTouch-to-log NFC & Elapsed Clock
Touch an NFC sticker on your pill bottle or tap your home screen. The elapsed timer resets in 1 millisecond on-device.
Everyday Life100% On-Device Privacy
Zero cloud accounts, zero analytics, zero data brokers. Your sensitive medical history never leaves your phone.
Included freeConnected Logs Family Sync
Live, end-to-end encrypted sync between phones. Know your elderly parents or kids took their pills with zero nagging calls.
See elapsed and remaining time. A clear timer shows time since the last event; an optional per-tracker configured interval adds a remaining-time countdown and explicit early-log confirmation.
Glance without wasting power. The Adaptive Display Engine uses event-paced updates, truthful frame-rate controls, and deterministic burn-in shifting on the OLED-first always-on screen.
Make every tracker recognizable. One identity editor handles names, built-in icons, transparent custom PNG/WebP icons, photos, framing, and accent colors before or after creation.
Find the NFC sweet spot. Device-aware antenna guidance helps position a tag while preserving normal background scans and safe tag programming.
Keep records close. Your timeline lives on your device, with encrypted backups available when you need them.
Bring it together. Save PulseTrace readings alongside your medication logs for a more complete personal record.

A log made from the TapRelay band, a game controller or NFC now shows its automatic after heart rate on the open screen the moment it is taken. No swiping back.
TapRelay 0.6.5 can show how long since a LastDose log, when it was, the heart rate recorded with it and how many today. Read-only, through the same signature-pinned link as logging; nothing else is shared.
Heart-rate history: tap the live heart rate for a graph of your band's readings over 1 h, 6 h, 24 h or 7 days, with average, min and max. It never leaves the phone.
Long-press the live heart rate to choose its size, position on the always-on screen, heart icon, colour and the LIVE tag.
Fixes
A band left on its charger no longer shows or records a frozen "live" reading.
TapRelay can log into LastDose again after LastDose is reinstalled. The link no longer depends on which app was installed first; the ARBH Labs signing-certificate check still guards it.
Verified on a Pixel 7: an Xbox controller button mapped in TapRelay wrote exactly one entry without LastDose opening.
Live Xiaomi Smart Band 9 heart rate arrives from TiltTrace 1.2.2, which reads Notify for Xiaomi. Keep TiltTrace open and the LIVE HEART RATE card and log stamping use that stream.
Fixes
LastDose no longer opens its own Smart Band connection while Notify for Xiaomi is installed, so it cannot fight Notify for the band.
Removed an unreleased Notify receiver that could never deliver heart rate.
Verified on a Pixel 7: the signed release showed changing live BPM matching TiltTrace and Notify.
Cloud Backup & Restore: back up your full history, elapsed timers, photos, vital records and settings to a private app folder in your own Google Drive. Only LastDose can read the backup, and it never passes through an ARBH Labs server.
Automatic scheduled backups (daily, weekly or monthly), with Wi-Fi-only and include-photos options, plus one-tap restore when you move to a new phone.
Restore replaces the records on the phone with the backup and takes a local safety snapshot first - it never silently duplicates history. Premium feature; sign in with Google to enable.
Reliability
Hardened the optimized release build so scheduled background work - including automatic backups - always runs.
In-place upgrade from 7.1.4 preserves all data; the database stays at v28.
Includes everything from 7.1.4 (Always-On Display 3.0, Tap Actions, configured intervals).
Always-On Display 3.0: a glanceable display shaped around the phone's camera cutout - independent left and right status groups, per-element size from Hidden through Hero for the clock, battery, connectivity, active timer and log info, presets (Minimal, Balanced, Battery Focus, Timer Focus, OLED Minimal), and a live device-preview customizer.
Tap Actions: program an NFC sticker to log, open, or take a measurement for a tracker in one tap. The tag holds only an anonymous random code; the log name, amount and history never leave the phone. Free keeps one Tap Action active; Premium unlocks unlimited tags and camera-measurement actions.
Reliability
NFC Tap Action logs now refresh the home screen, today's total and the elapsed timer as soon as you return to the app. The log always saved correctly; previously the card could keep showing pre-log values until the app was reopened.
Replacing a lost or damaged NFC tag revokes the old tag: only the freshly written tag triggers the action, and the tracker, action and usage history are preserved.
The NFC confirmation prompt uses future-tense wording and never records a log until you press Log.
Includes everything from 7.1.3 (optional configured intervals, corrected built-in covers). In-place upgrade preserves all data; database stays at v28.
Explore logging history well beyond the previous 24-hour focus.
Quickly inspect Today, Yesterday, 7-day, 30-day and all-time activity.
Jump to any past date with a calendar and see that day's totals, count and logs.
Daily totals, logging frequency, 7-day and 30-day averages, and a comparison with the previous equivalent period.
Adaptive logs-per-day chart for longer-term patterns.
Add backfilled entries for a real past date and time.
Hide individual entries behind a private PIN in Settings › Privacy.
Reliability
Today and Yesterday now use correct local calendar-day boundaries.
Database upgrades to v27 (one additive per-event flag) with no data rewrite; in-place Pixel 7 upgrade verified with records, events, metrics, photos and settings unchanged.
