The chatbot’s weekly check ins reduced workout skipping by 41% for surveyed users. -

Frustrations That Need Fixing:
-
Subscription Cancellation Maze
Android users report:-
Cancellation options buried in Play Store settings
-
Charges sometimes continue post-cancellation
Workaround: Email android[at]skimble.com with receipt screenshots.
-
-
Ad Overload in Free Version
Expect 15-30 second ads between workouts. Less intrusive during strength sessions (natural rest periods), but disrupts yoga flows. -
GPS Glitches
Older Samsung and LG phones often lose tracking mid run. Temporary fix: Carry your phone (don’t armband it) for better signal.
Workout Trainer AI Heart Rate Zone Guide – Train Smarter
Heart rate training separates casual exercisers from results-getters. Here’s how to leverage the app’s tools:
Step 1: Find Your Max Heart Rate
The app estimates it as (220 – your age), but for accuracy:
-
Do a 3 minute all out sprint (track with GPS)
-
Note the highest BPM reached
-
Manually input it in Settings > Heart Rate Zones
Step 2: Target the Right Zones
Zone | % of Max HR | Best For | Example Workout |
---|---|---|---|
Fat Burn | 60-70% | Weight loss | 45 min brisk walk |
Cardio | 70-80% | Endurance | 30 min jog |
Peak | 80-90% | Performance | Sprint intervals |
Step 3: Use Live Alerts
Enable zone notifications to buzz when you drift too high/low. Ideal for:
-
Staying in fat burn during walks
-
Hitting peak zones during HIIT

Avoiding overtraining during lifts
