Questions
Asked and answered.
Which devices does Sig run on?
Sig runs on iPhone and iPad with iOS 27 and iPadOS 27, with a layout designed for each rather than one stretched to fit. On iPhone Duo, Sig opens across the fold without losing the reader's place, and on Macs with Apple silicon, Sig runs as the iPad app. Sig is not available for Android or Windows.
Sig supports Siri, Shortcuts, and Spotlight, Home Screen widgets, VoiceOver, Dynamic Type through the largest accessibility sizes, Reduce Motion, and Increase Contrast.
For example, on iPad the sidebar keeps Drugs, Conditions, Guidelines, Tools, and Updates in view while a condition page fills the detail column. Additionally, on the open iPhone Duo display, the Antimicrobial Spectrum shows the whole organism-by-antibiotic grid.
The screenshots on this site were captured from the current build in November 2026. Our data ship in the app bundle, so the 15,497 recommendations are the same on iPhone and iPad.
Do I need an account to use Sig?
No, and Sig will never require one. Sig has no sign-in, no Sign in with Apple, and no password, and the privacy policy makes the absence a commitment rather than a description. A planned optional subscription would be tied to the Apple Account through Apple's In-App Purchase, with nothing to sign in to.
The practical effect: there is no Sig account to be breached, sold, or subpoenaed.
Our data hold no user records at all. The no-account commitment sits in section 2 of the privacy policy, effective November 2, 2026.
For example, if Sig Pro launches as planned, a subscription bought on an iPhone would appear on the same person's iPad automatically, because Apple records the purchase against the Apple Account. Additionally, Restore Purchases would remain available as a fallback, and the app never asks for an email address or a password.
Can I add healthcare observances to my calendar?
Yes. Sig publishes a subscribed calendar of 29 healthcare observances at webcal://get-sig.app/observances.ics. For example, American Pharmacists Month, National Pharmacy Week, and Pharmacy Technician Day appear with dates, and subscribers using Apple Calendar on iPhone, iPad, or Mac see the calendar refresh about once a week.
Every event is all-day and marked free, so the calendar never shows the subscriber as busy. Each event names the sponsoring organization and the dating rule, such as the third full week of October, so the date can be checked against the sponsor's own page.
Our data cover 29 observances, and the calendar file spans 2025 through 2030. Subscribing fetches one file from get-sig.app with no account or identifier. To stop, delete the Sig calendar in Calendar. Additionally, the same observances appear in the app's Healthcare Observances tool and widget.
Is Sig an FDA-cleared medical device?
No. Sig is reference and decision-support software for healthcare professionals and has not been reviewed or cleared by the FDA. Sig is built to sit within the clinical decision support description in section 520(o)(1)(E) of the Federal Food, Drug, and Cosmetic Act.
Any decision made by a pharmacist using Sig belongs to the pharmacist, under a personal license and judgment. Where Sig and the FDA-approved labeling or an institution's policy disagree, the labeling and the policy control.
Additionally, our data show the basis on every row: 100% of the 15,497 recommendations name the source section. The Terms of Use have stated that Sig is not a medical device since September 21, 2026.
For example, every Sig calculator result lists the inputs used, the method, and the citation, so the basis can be reviewed rather than trusted. According to the FDA's guidance on clinical decision support software, independent review by a healthcare professional is the criterion the design is built around.
When can I download Sig?
Sig is not yet on the App Store or in open beta. Sig will be released once the author is a registered pharmacist, expected after graduation in December 2026, and a TestFlight beta opens first. An email to support@get-sig.app joins the beta and brings word of the day Sig ships.
The waitlist is an email to us and nothing more: no account and no marketing list. Removal is available at any time on request.
To join: (1) send an email to the support address above; (2) accept the TestFlight invitation from Apple on arrival; (3) install the build and send feedback from inside the app.
For example, a beta tester receives an invitation through Apple's TestFlight app and installs the build. Additionally, the beta is free, and a tester can leave at any time by deleting the app or asking to be removed. Our data show the build already holds 15,497 recommendations and 434 decision trees, as of November 3, 2026.
Be in the first build.
Sig opens as a TestFlight beta before it reaches the App Store. One email is the whole sign-up: no account, no marketing list.
