Three promises

An honest price
Free at launch, logging stays free.
You’re in charge
Your plan, your pace; pro options when you want them.
What bothers people about fitness apps
The most common complaints in 1–2 star reviews of existing fitness apps on the App Store (our own analysis of public reviews, October 2026) – and how Vectryn answers them.
Subscription trouble
Trials quietly turn into expensive subscriptions, cancelling is hard, features that used to be free suddenly cost money.
Vectryn: an honest price instead of a subscription trap.
Lost data
Workout history disappears when creating an account or after updates.
Vectryn: your data belongs to you and stays on your device.
Patronising AI plans
The app decides what and when you train and ignores what you set.
Vectryn: you decide about your plan.
Overload
Too many features, unclear controls.
Vectryn: simple to start, pro options only when you need them.
Everything in one place
Training
Plans from templates or your own, a workout mode with a large current set, rest timer, plate calculator and strength progress per exercise.
Nutrition
A food diary with calories and macros, food search and barcode scanning, quick add, recipes and copying meals.
Body weight
Log your weight, see the chart and weekly trend, and optionally let your calorie target adjust to your actual progress.
Apple Health
Reads today’s steps and active calories, saves finished workouts, and syncs body weight in both directions.
Your health data stays on your iPhone.
No account. No ads, no analytics tools, no tracking in the app. Health data doesn’t leave your device and is never used for advertising.
Coming soon to the App Store
Vectryn is in development and isn’t in the App Store yet. Release is planned for around January 2027.
