New: your Apple Watch is a real training companion — REBL opens on your wrist at workout start, with live heart rate, calories, and rest countdowns.
REBL tells you what to do next — not just what you already did.
Most lifting apps are just a logbook. REBL's offline suggestion engine tells you the exact weight and reps to hit on your next set — tuned to your training history, your equipment, and how hard your last session actually felt. No internet, no account, no guesswork.
NEW — KNOW WHEN TO PUSH
REBL now scores your readiness 0–100 from your actual training — recent workload, session intensity, and how you said you felt. Check it on the home-screen widget before you even open the app, and see how hard every workout really was (Light to Very Hard) on your post-workout summary. Computed on your phone. No wearable required.
WHAT YOU GET FREE
- A smart engine that prescribes your next set, fully offline

REBL PRO — YOUR AI COACH
Upgrade for an AI coach that reasons over your training, not generic templates:
- Daily, weekly & monthly insight — what changed, what's working, what to push next
- An adaptive program that plans your training in blocks and adjusts when it drifts
- A post-workout recap — the coach's read on every session you finish
- Query Coach — ask anything about your training, form, or program
- Per-exercise form cues tuned to your goal, experience, and any injuries you flag
PRIVATE BY DEFAULT
No accounts. No ads. No tracking. Your data lives on your device and syncs through your own iCloud. The AI works out of the box — no login or API key needed.
Built by a lifter, AI-paired. If you've outgrown a spreadsheet and want structured progression with a coach's judgment, REBL is built for you.

This has been the type of app I’ve always wanted to have for fitness. It not only makes planning and executing a workout easy, but also gives you proactive insights into your progress. Features like the embedded timer, suggested weights, the AI strength coach and the per-workout form tips allow me to stay in the app and focus on what matters most: accomplishing my fitness goals
Keeps me accountable
Midwest__Muscle
This app has made it way easier to stay on top of my training. Logging workouts is quick, everything stays organized, and seeing my progress keeps me motivated to keep showing up. Definitely recommend it to anyone looking to stay consistent and make progress!
Took the guesswork out for me
DACseattle1
Finally a workout tracker that does the thinking for me — it gives me theexact next weight and reps. The AI coaching is genuinely helpful and adapts as you go. Simple, clean, it's kept me consistent and pushed me more than I would have done myself.
The best!!!
Ruthless lifter
I’ve used a lot of workout apps. This one is heads and shoulder above the rest. It actually gives me a routine I can follow, the AI tells me what I should be doing and gives me feedback about my actual workload (aka how much I’m lifting). It’s been a game changer!! I’m on a 3 week streak!

• The workout timer is always on screen, whichever page you're on
• Rest counts down right under your next set's weight and reps — no more losing the prescription while you rest
