TrainerStudio VS PrivacyNotes

TrainerStudio's answer

Personal trainers and nutritionists who coach clients online, in person or both. It works for independent trainers signing up their first clients as well as coaches running a large client list.

PrivacyNotes's answer:

People who want their private life in one private place: notes, plans, passwords, a journal and health records. It fits independent professionals who keep sensitive material, such as lawyers, journalists, therapists, doctors, developers, researchers and founders. It also fits anyone who is tired of paying for five apps that each hold one part of their life.

TrainerStudio's answer

TypeScript, Node.js, NestJS, MongoDB, React, Vue.js, Next.js, Capacitor (iOS and Android), AWS, Stripe, ClickHouse, Datadog

PrivacyNotes's answer:

React, TypeScript, Vite and Tailwind CSS.

TrainerStudio's answer

Every plan, including the free one, gives the trainer a client app under their own brand (name, logo and colors) on iOS, Android and the web. Workouts, nutrition with recipes and macros, check-ins, chat and payments all live in that same app, so clients don't need anything else.

PrivacyNotes's answer:

PrivacyNotes keeps your notes, tasks, passwords, journal, files, calendar, contacts and bookmarks in one app, with mood and medication tracking. Everything is encrypted on your device with XChaCha20-Poly1305, under a key from a 12-word recovery phrase. Most privacy apps do one of these jobs and charge for it every month. PrivacyNotes does all of them, and Pro is a one-time purchase. The apps are open source, so anyone can check what they do.

TrainerStudio's answer

The free plan covers up to 3 clients with every feature and no credit card, so trainers can coach real clients before paying anything. Paid plans start at €19/month, prices follow the cost of living in the trainer's country, and nutrition, load tracking and payments are included instead of being sold as add-ons.

PrivacyNotes's answer:

Three reasons:

• One app, not a stack of subscriptions. Standard Notes, Day One, Daylio and Bitwarden each cover one part of your life. PrivacyNotes covers all of them, with one price, paid once.
• Encrypted on your device. Your notes are always encrypted, on your device and on the way to our servers in Zurich, Switzerland. With self-custody, the server holds nothing that opens your notes.
• Open source, no ads, no trackers. The apps and the encryption code are published for review, and there is no ad, tracker or analytics of what you write anywhere in the app.

TrainerStudio's answer

TrainerStudio was born in Spain in 2021, built in Pontevedra. We saw personal trainers running their business on spreadsheets, PDF routines, late-night WhatsApp questions and payments chased one by one. Their income was capped by their calendar: every new client meant more admin, not more time coaching.

We built TrainerStudio so one coach can train more clients in less time and deliver a service clients notice: every coach gets a branded app with their own logo, workouts with video, nutrition plans, check-ins, chat and automatic payments. Today more than 12,000 coaches use it, mostly in Spain and Latin America, in five languages.

PrivacyNotes's answer:

PrivacyNotes started from a simple frustration: staying organized meant spreading your life across half a dozen apps, each with its own monthly bill. We wanted one place for notes, tasks, a journal, files and passwords, encrypted on your device, and paid for once instead of forever. So we built the encryption first, made it the base of every feature, and published the apps as open source so the promise can be checked, not just believed. Everything else grew from one rule: your data is yours.

PrivacyNotes's answer:

We do not keep a customer list to show, and that is on purpose. You can sign up with only a 12-word phrase, with no email and no name, and the app has no trackers and no analytics. So we do not profile the people who use it. A privacy product that watched its users closely enough to name them would miss its own point.
