Capabilities
What you can do with Soma
Engineered around real cycle biology, with no intrusive questions, no mandatory fields, and check-ins that respect your day.
01
Track your cycle and symptoms in seconds.
A frictionless check-in that never gets in your way. Log physical symptoms, moods, cervical fluid, basal body temperature, and personal notes without navigating menus or answering surveys.
- Fanned swipe-deck cards for one-tap mood selection
- Flexible symptom tags with zero mandatory fields
02
Understand your timing without synthetic promises.
Human biology is not a metronome. Soma calculates honest phase windows derived from your actual physiological variance, adjusting gently for stress, travel, illness, or irregular cycle months.
Calculations reflect your own baseline history — never compared against generic normative datasets.
Estimated window based on your last 4 recorded cycles (avg 29.4 days).
03
See the why behind your patterns.
Connect the dots across weeks and seasons. Soma spots correlations between sleep quality, mood rhythms, temperature fluctuations, and recurring physical symptoms.
04
Keep it strictly to yourself.
Your journal stays sealed behind your phone's native secure storage. Use discreet mode to mask app markers and glanceable widgets from people nearby.
- App lock triggered instantly when you switch away
- Discreet widgets with neutral, non-clinical labels

Requires Face ID or your device passcode to open.
05
Share with someone you trust.
Need a partner, doctor, or family member to know your expected cycle window? Share a read-only encrypted summary. Completely opt-in and revocable at any moment with a single tap.
Read-only, opt-in, and revocable at any time.
Partner sharing
Phase & fertile window only
Symptoms, intimate notes, and body weight are strictly excluded from shared projections.
06
Ask your cycle anything.
Soma AI is an optional Premium assistant that reads the patterns you already track and explains them in plain language — on your device first, with a clearly labelled cloud fallback for harder questions.
Non-diagnostic. Only sanitised labels are ever sent, never your notes.
Your last three cycles averaged 29.4 days, up slightly from 28.1 — mostly a longer follicular phase, which is common.
On your deviceArchitectural principles
Why Soma
“Private by default is not a feature. It's the point.”
Pattern recognition
Questions about your body, answered by your data.
Clear, non-judgmental pattern cards that emerge naturally from what you log over time.
Why was my period late last month?
Soma flags that your follicular phase shifted by 4 days during travel, while your post-ovulatory luteal length stayed consistent at 14 days.
When do my sleep disruptions occur?
Nighttime restlessness lines up with the progesterone drop in the final 48 hours of your luteal phase, rather than with weekday work schedules.
How accurate is my fertile window?
Derived from combined cervical fluid changes and your sustained basal temperature shift, instead of a fixed calendar formula.
Soma doesn't diagnose or replace medical advice. It helps you notice patterns.
Soma AI
Ask your cycle anything.
An optional assistant that reads only the patterns you already track, explains what they might mean in plain language, and always tells you where the answer came from. It is a Premium feature and it is never in the way.
On-device first
When your phone can answer, it does. Nothing leaves the device for a question it can already handle.
Cloud when it helps
Harder questions fall back to a cloud model, and the answer is clearly labelled as cloud-generated.
Only patterns, never notes
The assistant receives sanitised labels like phase and trend flags, never your raw dates, IDs, or free-text notes.
The assistant is non-diagnostic and not a substitute for medical advice. It explains patterns, and you stay in control of every question you ask.
Your logged energy dipped through the late luteal phase, which lines up with the same window in your last three cycles, rather than with your sleep schedule.

Frequently asked questions
How does Soma work completely offline?+
The cycle engine, prediction logic, and symptom logging all live in a sandboxed database on your phone. You can install Soma, turn on airplane mode indefinitely, and every core feature keeps working without an internet connection.
Where does my health data live?+
On your phone, protected by your operating system's built-in storage encryption (iOS Data Protection and Android Keystore). There is no central profile of you to sign into, and core tracking works without one.
How does backup work if there are no accounts?+
Backup is strictly opt-in and off by default. When you turn it on, your records are encrypted on your phone before they are uploaded, and recovery is tied to the account you sign in with so a new phone can restore your history. It is not required for any core feature.
Does Soma replace a healthcare provider?+
No. Soma is an observational companion built to help you understand your personal timeline and patterns. It doesn't provide medical diagnoses, treatment plans, or emergency guidance. For health concerns, consider talking to a healthcare provider.
Does Soma have an AI assistant?+
Yes, an optional Premium assistant. When your phone can answer, it does so on-device; harder questions use a cloud model, and those answers are clearly labelled as cloud-generated. It only ever receives sanitised labels like phase and trend flags, never your raw dates, IDs, or notes. It explains patterns and never provides medical advice.
When and where is Soma launching?+
Soma is coming soon to iOS (App Store) and Android (Google Play). Waitlist members will receive private beta invitations via TestFlight and Google Play Beta first.
