First launch, disclaimer acceptance, and creating your profile.
When you open Cellular Keys for the first time, the app loads for a few seconds while it initializes securely. After that, it will prompt you to authenticate using Face ID, Touch ID, or your device passcode. This happens every time you open the app or return from the background.
Before accessing any features, you must read and acknowledge the Terms & Disclaimer. This is required on first use and will reappear if the disclaimer is updated in a future release.
Cellular Keys is a personal logging tool only. It does not provide medical advice. Always work with a licensed healthcare provider before starting, modifying, or stopping any compound regimen.
After accepting the disclaimer you will land on the Home tab with a prompt to create a profile. Tap it and fill in:
You can add your healthcare provider's full contact info inside the profile: name, specialty, clinic, phone, email, and address. Tap the profile menu, then Edit Profile, then scroll to the Healthcare Provider section.
Your daily at-a-glance view of trends, doses, and progress. The Home tab is the central hub of Cellular Keys. It is organized into collapsible sections you can expand or collapse by tapping the section header.
Each pending dose row shows the compound name, the prescribed dose amount, and (if you have a reconstituted vial linked) the calculated volume to draw in mL and the equivalent in insulin units (0.1 mL = 10 units). Tap a row to quick-log the dose immediately.
Tap the ••• button in the top-right corner of the Home tab to access:
Browse, search, and reference 170+ compounds with full dosing data. The Library tab is your reference for every compound in the app. By default it shows vitamins, minerals, supplements, and FDA-approved compounds. Research chemicals are hidden until Research Mode is unlocked.
A horizontal chip row at the top lets you filter by category. Tap All to see everything, or tap any category chip to jump to that group. Available categories include:
After selecting a category, a second chip row appears showing the specific intended uses within that category. For example, selecting Supplements might show chips for Joint health, Cognitive function, Antioxidant, and so on. Tap a micro-goal chip to narrow further.
Tap the search bar at the top and type any keyword. The app searches compound names, mechanisms, and intended uses simultaneously. Results update in real time.
Tap any compound row to open its full detail page. This includes:
At the bottom of any compound detail view, tap Add to Protocol. This opens the Add Protocol form pre-filled with the compound's library dosing defaults, which you can then adjust.
Orange Research badges appear on compounds that have no FDA approval or regulatory clearance for human use. These are only visible when Research Mode is enabled.
Track active compound regimens with cycle scheduling and daily progress. A protocol is a structured regimen for a single compound. It defines the dose, frequency, on/off cycle, and total duration. The Protocols tab shows all active and upcoming protocols sorted by status.
The recommended way to add a protocol is through the Library:
Protocol progress updates daily. The progress bar on each row reflects elapsed cycle days. Days remaining are shown in the top-right of each row.
Inventory tracking with automatic concentration calculations. The Vials tab tracks your physical inventory, the vials you have purchased and reconstituted. When a vial is logged and reconstituted, the app automatically calculates the concentration (mcg/mL) and uses it to show you exactly how many mL and insulin units to draw for each dose on the Home tab.
The concentration formula is simple: (Total mg × 1000) ÷ Volume mL = mcg/mL. For example, a 5 mg vial reconstituted with 2 mL of bacteriostatic water yields 2500 mcg/mL. Once this is saved, every dose on the Home tab will show the exact volume to draw for your prescribed dose.
Vials show a green Reconstituted badge when they have been mixed, and an orange Dry badge when they are still lyophilized powder. Update this when you reconstitute to activate the volume calculations.
Record every dose with time, amount, and optional notes. Dose logging tracks what you took and when. There are two ways to log a dose.
The fastest method, no navigation needed:
For logging outside of Today's Doses, or for doses not tied to a protocol:
The Dose Log tab (or Dose History from the Home menu) shows your last 30 days of logs grouped by date. Tap any log entry to see its full detail. Swipe left on an entry to delete it. Deleted dose logs cannot be recovered. The app stores all data locally and there is no cloud backup.
Periodic biometric check-ins to track how your body is responding over time. A snapshot is a timestamped record of your key biometrics. Taking snapshots regularly lets you see how your body trends in response to your protocol over weeks and months.
Fields you can log in a snapshot include:
Tap Snapshot History from the Home tab menu or the History section to see all your snapshots in reverse chronological order. Tap any snapshot to view its full detail. The Body Trends card at the top of the Home tab always shows the most recent snapshot values at a glance.
Separate tracking records for multiple individuals on one device. Cellular Keys supports multiple profiles on the same device. Each profile has its own entirely separate set of protocols, dose logs, vials, snapshots, and settings. Profiles do not share any data with each other.
Tap the Switch button in the top-left corner of the Home tab to open the Profile Switcher. Tap any profile to make it active. You can also add a new profile from this screen.
Tap ••• then Edit Profile on the Home tab. From here you can update:
In the Profile Switcher, swipe left on any profile and tap Delete. This permanently removes all data associated with that profile including all protocols, logs, vials, and snapshots. This action cannot be undone.
Curated links to peer-reviewed databases and scientific resources. The Research tab provides direct links to external scientific databases. Tap any link to open it in your browser. All links open peer-reviewed or government-maintained resources.
The Research tab also includes compound-specific PubMed searches organized by category, so you can quickly pull up current literature for any compound you are tracking.
External links open third-party websites not affiliated with Cellular Keys. Tapping a link opens that site in your browser, subject to its own terms and privacy policy. The app does not transmit any of your data when you follow these links.
Optional access to compounds not approved for human use. By default, the Compound Library shows only FDA-approved drugs and legal supplements. Compounds classified as research chemicals (those with no regulatory approval for human use) are hidden. A banner at the bottom of the Library indicates how many compounds are hidden.
Tap ••• on the Home tab and select Disable Research Mode. Research compounds will be hidden again immediately. Your setting persists across app restarts.
Research compounds have no established safety profile for human use. Their inclusion in the library is for informational tracking purposes only. Always consult a licensed healthcare provider before tracking any unapproved compound.
How your health data is protected on your device.
Every time you open Cellular Keys (or return to it after it has been in the background) the app requires authentication via Face ID, Touch ID, or your device passcode. The app locks automatically the moment you leave it. There is no grace period or timeout to configure.
All of your data (profiles, protocols, dose logs, vials, snapshots) is stored exclusively on your device using Apple's SwiftData framework. There are no accounts, no cloud sync, and no servers. Nothing you enter is ever transmitted anywhere.
To remove all data, delete the app from your device. iOS will remove all app data along with the application. There is no account to close and nothing stored remotely to request deletion of.
