The three kinds of tools trainers actually use
Ask working trainers what they program in and you hear the same three answers:
- Spreadsheets. Excel or Google Sheets, one tab per client. Total control, zero help, and the client’s logs live in a text thread somewhere else.
- All-in-one coaching platforms. Billing, scheduling, a workout builder, habit tracking, nutrition, a client app. Good at the business. The programming part is usually a template library and a drag-and-drop builder, so the thinking is still all yours and the typing is still all yours.
- A notes app and memory. For the trainer with eight clients, this honestly works until it doesn’t.
None of these are wrong. None of them shorten the programming hour, because none of them write the first draft.
What Spotter does
- Drafts each session from your own programming profile and the client’s logged history, with a summary line that says why. See AI workout programming.
- Swaps an exercise with a reason: tap it, say why it won’t work, get three ranked alternatives. See exercise substitution.
- Assigns and logs. One tap sends the approved session; the client logs load, reps and RPE per set on their phone. See RPE-based programming.
- Drafts next week from the log, applying your progression rules. See adaptive programming.
- Books sessions on a month calendar; clients can request a time and you accept, counter, or decline, with a push notification either way.
- One message thread per client, in the app they already open to log. Written by you, never by Spotter.
- Your own exercises in the library next to the starter set.
- Trainer-only clients for the people you only ever see in person: private notes, a progress view, and a quick “we did this today” log, without the client app.
What Spotter doesn’t do
This list is as important as the last one, and it is deliberate.
- No billing, payments, packages or invoicing.
- No nutrition planning or meal tracking.
- No marketing funnels, lead capture or website builder.
- No medical advice. If a swap reason sounds like an injury, it says so and suggests a referral.
- No automated messages, check-ins or reminders sent in your name.
- No program goes to a client without you assigning it.
So where does it fit? Next to your billing tool, not instead of it. If you are on an all-in-one platform for payments and scheduling, Spotter is the programming layer you open when it is time to write the week. If you are on spreadsheets, it is the first thing that has ever written the first draft for you and put the client’s logs back in front of you without a text thread.
On the phone, without an app store
Spotter is an installable web app. Open the link on an iPhone or Android phone, add it to the home screen, and it runs full-screen with push notifications for session requests and messages. There is nothing to download, no store listing, and an update is live the moment it ships. It works in a desktop browser too, as a phone-width column, because it was designed for the phone first.
Who it is for
Working trainers, whether gym-employed, independent, or in a small studio, with some clients who train without them during the week. The invite form asks roughly how many clients you have and how you program for a new one, because the beta is being built around real programming habits rather than a feature checklist. It is free while the beta lasts, and pricing is not set.
