### 3/5 — Great functionality, but a bit bare bones

*2022-01-01*

If you just want to make crazy combinations of timers for a relatively calm atmosphere, you will give this app 5 stars.
If you’re looking for some visual cueing beyond  elapsed/remaining, you won’t find it here (green for intervals, blue for rounds, no other options).
If you’re looking for sounds to cut through a noisy workout (or other) space, the last 5 second beeps and calm TTS voice won’t get you there.
If you’re thinking, “just give me a timer I can configure any way I want; I don’t care about fancy,” then you’re done searching.

**Developer response:** Thank you for insightful feedback.
