A personal trainer app that’s always on.
An automated AI coach that plans your workouts, answers your questions and adapts as you train.
What an always-on coach does
Specter is a personal trainer app that lives on your phone. It plans your workouts, explains the exercises, answers questions in the middle of a set, logs your meals and adjusts the next session from how this one went. It is there at 6 a.m. and at 9 p.m., on a travel day or a rest day.
It is automated coaching, not a person
Specter is an AI coach. There is no human trainer reading your messages. That is a real difference, and the table below is honest about both sides.
| Specter | A human trainer | |
|---|---|---|
| Availability | Any time you open the app | Scheduled sessions |
| Your equipment | Plans around what you own and changes when you do | Depends on the trainer and the location |
| Watching your form | Describes cues and answers questions; cannot see you move | Can watch and correct you in person |
| Injuries and health | Takes your limits into account; not medical advice | Can work with your doctor or physio |
What you can ask
A workout coach you can talk to.
- “Plan today’s workout.”
- “I only have 20 minutes.”
- “What is this exercise, and how do I do it?”
- “Log my lunch.”
Trainer app questions
Is Specter a real person?
No. Specter is an automated AI coach inside the app. It is not a human trainer, and it does not give medical advice.
What does it cost?
You download it from the App Store. Some features need a paid subscription, billed and managed through Apple. Current pricing is on the App Store listing.
What happens to my data?
Your workouts and chats live on your device, and in iCloud if you turn that on. Specter does not keep your chat history on its servers and does not sell your data. Messages and photos are sent to an AI provider to produce each reply. The full details are in the privacy policy.
Your coach is waiting.
