RepDB's answer

RepDB is sold as a one-time download, not a metered API — you own the JSON/SQLite data and WebP images outright, with no rate limits, no per-request billing, and no risk of the vendor cutting off access. It's also the only dataset in this space with EN/DE/ES translations, transparent (alpha-channel) images with no watermark, muscle-group highlighting, safety/goal tags, and looping animations on the higher tier.

Phaserr's answer:

Most AI fitness tools write the program for you. Phaserr does the opposite: AI drafts a training block in seconds, and then the coach edits, reshapes and approves it. The software never publishes a program on its own — the coach stays the author, and the athlete's plan still carries their name and their thinking.

That one rule shapes everything else: every AI output lands in an editable block, not a locked plan.

RepDB's answer

RepDB grew out of a consumer workout app its creator was building solo. Sourcing exercise images and data meant either paying for a subscription API with usage caps and no caching rights, or producing everything from scratch. The illustrated, multi-language dataset was built for us first, then split out as its own product once it became clear other indie developers had the same problem and preferred to buy the data outright rather than rent it through an API.

Phaserr's answer:

We're not coaches — that's the honest starting point. One of us is a designer, the other an engineer. We kept seeing the same thing: skilled coaches doing genuinely expert work, then losing hours to spreadsheet mechanics and PDF exports.

Because we're not coaches, we made a rule we won't break: the software never writes the program. It can draft, structure and speed things up, but the training decisions stay with the person who is qualified to make them. Phaserr is being built in the open with the coaches who use it — we ship, we listen, we fix.

RepDB's answer

Most alternatives are subscription APIs — you pay monthly, you're capped on requests, and ExerciseDB's terms of use explicitly forbid caching or storing the data at all, so every image render is a live paid API call. RepDB is the opposite: pay once, download the files, self-host with zero ongoing dependency. It's also the only option offering true DE/ES localization and transparent images instead of a white box behind every exercise.

Phaserr's answer:

Two reasons, depending on what you're leaving behind.

If you're coming from a spreadsheet: you get real structure — multi-week blocks, sets, reps, load schemes, progressions — and your athletes open the session on their phone instead of squinting at a shared sheet or a PDF.

If you're comparing against other coaching platforms: most of them either bury programming under billing and CRM features, or hand the programming over to AI entirely. Phaserr is built around the block builder, and the AI is a drafting assistant that you edit — not an autopilot. Free for individual coaches, AI included.

RepDB's answer

Solo developers and small teams building fitness or workout-tracking apps (iOS, Android, web) who need licensed exercise images and structured exercise data, but don't want to build their own media pipeline or depend on a rate-limited third-party API.

Phaserr's answer:

Independent strength and conditioning coaches and personal trainers who write their own programs — the ones currently running everything out of Google Sheets or Excel and sending PDFs.

Typically a solo coach or a small team with a handful to a few dozen athletes, who cares about how the block is structured and doesn't want a platform making training decisions for them. Not gyms looking for billing and membership software, and not athletes looking for a workout app.
