Nine product types
Diffuser, roller bottle, massage oil, lotion, soap, perfume, room spray, candle, or custom. Each one brings its own measurement basis and its own expectation about whether a carrier is used.

About this release
Mia Blend Studio is in private beta, version 0.1.0 Beta 1, for iOS and Android. There is no public store listing, no account system and no purchase — beta access is arranged directly. Platform features are described as they work today, and anything planned is labelled as planned.
What it calculates
The arithmetic is the feature
A blend is a small calculation with a lot of ways to get it wrong. Mia Blend Studio picks a measurement basis from the product type, keeps the books in exact fractions, and tells you what it assumed.
Four ways to enter a material
Percent, drops, millilitres or grams — narrowed to the units that make sense for the product type, because a lotion is weighed and a diffuser is measured by volume.
The carrier is calculated, not guessed
The base is the batch size minus the actives. If the remainder would be negative, the app shows an error instead of quietly clamping it to zero and handing you a formula that does not add up.
Exact arithmetic
Values are stored as exact fractions rather than floating-point numbers, so 33.3 + 33.3 + 33.4 behaves predictably. Rounding happens for display only, and any rounding difference is stated.
Drops are your assumption
Drop counts convert using your own drops-per-millilitre setting — 20 by default, editable. The app labels that number as an assumption, not a physical constant, because dropper size, oil and temperature all change it.
Volume and mass stay apart
A millilitre-to-gram conversion stays unavailable until you supply a density, and the app explains why the field is disabled. Normalise to 100% is a deliberate action behind a confirmation, never something that happens on its own.

Saving and stock
From a formula you worked out to a shelf you can see
Blends, the materials they use and the stock on the shelf are one system, so what you can make is answered from your real inventory rather than your memory.
My Blends
Search and filter saved blends, mark favourites, duplicate, edit or delete with a confirmation. Unsaved changes are protected when you leave the editor, and recent blends sit on the Create screen for a one-tap return.
Blend history
Each save increments the revision and keeps a snapshot, so you can look back at the version of a formula you mixed last month instead of relying on memory or a note in your phone.
Inventory as lots
Materials are tracked as lots with a quantity, a unit and dates. Expired lots are excluded from availability rather than being consumed without a word. Set a low-stock threshold per material and get a shopping list of what to buy.
“What can I make?”
Every saved blend is checked against current stock and marked Ready or Short N materials, using the same calculation engine as the editor so the two cannot disagree. Deducting stock shows exactly which lots will be drawn down, and the last 50 deductions can each be undone.
Your data
It stays on your device
Mia Blend Studio keeps everything on your device. There is no account, no server and no sync, so there is nowhere for your blends to be sent and nothing to sign into when you want to use it.
- No account, no analytics, no ads
- No network calls during normal use
- Backups are JSON files you export and keep yourself
- Invalid backup files are rejected whole, not half-imported
- A recovery copy is written before any restore
- Diagnostics export carries version, build, platform, counts and schema — no blend content
Small things that count
-
Light and dark, four accents
Teal, blue, plum or amber, on either theme, with unit preferences for mL or fl oz and g or oz.
-
Contrast checked, motion respected
Text contrast verified at 4.5:1 or better by an automated check, reduced-motion honoured, and controls that carry screen-reader labels and roles.
-
The free plan holds five blends
At the cap you can still read, edit and export everything you already saved — only adding a new blend is blocked. Premium is not purchasable in the beta.
Limits, stated plainly
What it deliberately does not do
A blend is not safe because its percentages add up to 100%. The app is a calculation and record-keeping tool, and it says so in the product rather than only in the footer.
No numeric safety limits
Mia Blend Studio does not supply maximum dilutions, dosing guidance or IFRA compliance values. None were sourced, so none are shown — and it is not medical, dermatological, veterinary or regulatory advice.
Starter formulas are starters
All 18 formulas are marked as not editorially checked or safety assessed, in the app itself. Treat them as a starting point, not a recommendation. Cautions shown alongside a formula come from the material catalog, not from a safety review.
Request beta access
Mia Blend Studio is in private beta on iOS and Android. Tell us which platform you use and what you blend, and we will send the build details and the current safety notice.
