### 1/5 — Disappointing

*2025-01-06, version 3.0.3*

On Octopus Intelligent Go and was hoping for visibility of usage AND rates without having to wait for my monthly bill.  This App just assumes the rate to be used based on the time of day consumed which does not reflect the actual DYNAMIC rate that Octopus may apply outside of the default cheap times.  Hence, can’t see actual cost as rate is unreliable.  Disappointing.

### 2/5 — Fails to pick up gas tracker rates

*2024-03-14, version 3.0.2*

I loaded this specifically to track my gas consumption and cost. Unfortunately it doesn’t pick up the fact I’m in a changing tracker rate - you can only enter a fixed price

### 1/5 — Octopus

*2023-08-30, version 3.0*

### 5/5 — Great app.

*2023-03-10, version 3.0*

Does exactly what you want to check consumption & cost. My in-house meter does not distinguish between offpeak and dayrate this works perfectly giving exact daily cost.

### 1/5 — Octopus outgoing

*2023-02-03, version 3.0*

Good app works well with octopus usage data and all tariffs Need a app now to read outgoing agile gives kWh values but not cost but if your on agile then this is a good app Regards Stewart

### 1/5 — No isage

*2023-01-16, version 3.0*

Shows my usage as 0.00kEh every day. The tarrif it finds is correct but doesn’t show any usage?

### 1/5 — Can’t get it to work

*2023-01-04, version 3.0*

This app has given rise to endless frustration as I can’t get it to work

### 5/5 — Brilliant app

*2023-01-01, version 3.0*

Works perfectly, gives full insight to your use and average expected cost for the month.

### 1/5 — Watt a waste of 99p

*2022-12-29, version 2.1.2*

Could not log into octopus account and manual entry didn't work either.
Complete waste of time!
Shame on you App Store
