### 1/5 — Latest update drains battery

*2023-08-05, version 3.1.3*

The latest “pretty” update now causes the battery to drain on my iPhone 12 at an alarming rate. I can no longer leave the app running in the background which defeats the purpose of the app! Checking battery stats shows that the
latest version is using 65% of my total battery usage in an 8 hour period.

### 5/5 — Works Fine

*2023-07-31, version 3.1.3*

New interface is a bit prettier. Reliability seems OK. Watch app would be nice but otherwise does the job.
