App development for supplement brands
For daily-use products, an app turns a purchase into a habit. Formula Works designs and builds native iOS and Android apps for supplement brands — shipped to both stores, wired to your storefront and your subscription model.
When an app makes sense
Supplements are taken daily; most brands only speak to their customers at checkout. An app closes that gap — tracking, reminders, personalised guidance — which supports adherence, retention and subscription revenue. It isn't right for every brand, and we will tell you honestly if a website alone serves you better.
What we build
- Native apps for iOS and Android, designed, built and shipped to the App Store and Google Play
- Personalised onboarding — quizzes that tailor the experience to each customer
- Daily tracking and gentle, judgement-free insights
- Free-to-premium subscription models built in
- Privacy-first architecture: encrypted data the user can delete at any time
Built end to end: Genesyx
Genesyx is a fertility companion we built whole — Shopify storefront, native apps on both stores, onboarding quiz, cycle and pH tracking, and a free-to-Premium model. The case study below shows the full build.
Questions
How much does a supplement brand app cost?
Apps are scoped individually — the range depends on features, platforms and integrations. Tell us what you want the app to do and we will give you a fixed scope and price, the same way we price websites.
Can the app connect to my Shopify store?
Yes — storefront, subscriptions and customer accounts can all be wired into the app, so the website and app behave as one product.
Do I actually need an app, or is a website enough?
Most brands should start web-only, and we will tell you so. An app earns its keep when your product involves daily engagement — tracking, reminders, guidance — or when subscription retention is the battle you are fighting. If a website serves you better, that is what we will recommend.
Why build native apps rather than a web app?
Native apps live on the home screen, send push notifications, work with device features and carry the credibility of the App Store and Google Play. A web app is cheaper but sits a browser tab away from being forgotten. For daily-use supplement companions, presence on the phone is most of the point.
How long does a supplement brand app take to build?
Meaningfully longer than a two-week website — apps are scoped individually, and store review adds time at the end. We give you a fixed scope, price and timeline before work starts, the same way we price websites.
Who owns the app and its code?
You do — the codebase, the App Store and Google Play listings, and every byte of user data. We build it and can maintain it, but nothing is held hostage.
Can the app send reminders and notifications?
Yes — considerately. Daily-dose reminders, tracking nudges and gentle re-engagement are core to why supplement apps work, and they are designed to help adherence rather than nag.
How do you handle sensitive health data in an app?
Privacy-first, by architecture: encrypted in transit, minimal collection, and deletable by the user at any time. Genesyx handles cycle and fertility data — among the most sensitive categories there is — and was built so users stay in control of their own information.
Will Apple and Google approve a supplement app?
Health-adjacent apps get extra scrutiny, which is exactly why claims discipline matters inside the app too — store reviewers reject medical overreach just as regulators do. We build to the store guidelines from day one and have shipped through both review processes with Genesyx.
Do you maintain the app after launch?
Yes — operating systems move, devices change and stores update their requirements, so apps need ongoing care. Maintenance is scoped alongside the build so you know the running cost before you commit.
