Everything Tansira can do
A detailed look at every feature designed for people who take their readings seriously, without trusting their data to a stranger's server.
Full Offline Operation
Tansira works 100% without internet. Log readings, view 90-day trends, and export PDF reports whether you're in a basement, on a plane, or in a hospital with no signal.
SQLCipher Encryption
Every reading is encrypted at rest using AES-256 via SQLCipher, the same library trusted by financial and government apps. Your device key is generated locally and never leaves.
Multi-Guideline Classification
Choose between AHA/ACC (2025), WHO/ISH (1999), ESC/ESH (2018), or JSH (2025). The classification badge updates instantly when you switch; no re-entry needed.
Crisis Alerts
Readings at or above 180/120 mmHg (AHA/ACC) or 180/110 (other guidelines) trigger an immediate Crisis Warning screen. Tansira distinguishes between Hypertensive Emergency (with symptoms — call emergency services) and Hypertensive Urgency (without symptoms — contact a doctor urgently).
Deep Analytics
7-day to all-time views with averages, category breakdowns, morning vs evening comparison, circadian analysis, morning surge detection, weight trends, lifestyle tag correlations, medication adherence correlation, and optional weather correlation.
Medication Tracking
Add medications with dose times and receive local reminders at each scheduled time. Mark doses taken or skipped from the notification. Analytics shows whether on-time dosing correlates with better BP control in your data.
Family Sharing
Link devices with a family member or caregiver via QR code or 6-character invite code. Readings sync automatically over end-to-end encrypted channels. Enable crisis push notifications so a trusted person is alerted the moment you log a hypertensive crisis reading.
PDF Report Export
Generate print-ready PDF reports with your reading history, average values, trend chart, and optional doctor notes. Choose any date range and share directly with your doctor from the share sheet.
Health Platform Sync
Two-way sync with Apple Health (iPhone) or Health Connect (Android). Your BP readings appear alongside your other health data and any readings already in Apple Health or Health Connect are imported automatically.
Lifestyle Tags
Annotate readings with context — sleep, stress, exercise, alcohol, caffeine, salt intake, hydration, illness, or custom tags. Analytics surfaces which tags correlate with higher or lower readings specifically in your data.
Senior & Accessibility Modes
Senior Mode scales text to 1.4×, enlarges touch targets to 56 pt, and adds confirmation dialogs before destructive actions. High Contrast Mode communicates BP categories with both colour and shape/text for users with colour vision deficiencies.
Dark Mode
Full dark mode support that follows your system setting or can be locked manually. Designed for comfortable use in low-light morning reading sessions.
Accessibility First
VoiceOver and TalkBack are fully supported. All interactive elements meet 44×44 pt minimum touch targets (56 pt in Senior Mode) and WCAG AA contrast ratios. Available in English, Turkish, Serbian, and Indonesian.
Blood pressure guideline comparison
Different professional bodies define hypertension stages differently. Tansira lets you see which category your reading falls into under each system.

|---|---|---|---|---|---|
| AHA/ACC 2025 | < 120/80 | 120–129/<80 | 130–139/80–89 | ≥ 140/90 | ≥ 180/120 |
| WHO/ISH 1999 | < 130/85 | 130–139/85–89 | 140–159/90–99 | 160–179/100–109 | ≥ 180/110 |
| ESC/ESH 2018 | < 130/85 | 130–139/85–89 | 140–159/90–99 | 160–179/100–109 | ≥ 180/110 |
| JSH 2025 | < 120/80 | 120–129/<80 | 130–139/80–89 | ≥ 140/90 | ≥ 180/120 |
