### 2/5 — Does not support online play

*2026-04-03, version 2.7*

I bought this hoping I could use it for online play, but it is purely offline play. There is an “online” button, but tapping it just opens the web page in Safari. Given that there are other much better apps for scoring local darts like Dart Counter, for free (DC’s local play scoring is free, only their online play costs money), there’s no point in buying this app.

The n01darts website is a great free online darts service, though. Just use that. I am going to keep this app installed in case there is ever an update to add online play. Specifically I was hoping the app would keep my iPhone screen awake. So it would need to do that as well.

### 1/5 — Upgrade

*2026-02-04, version 2.7*

Update it pleases!
Add sound& …

### 4/5 — Hiányos

*2025-05-23, version 2.7*

Szuper program lehetne, de személy szerint nagyon hiányzik az adott leg átlagának a mutatása

### 1/5 — UtterRubbish

*2024-04-01, version 2.7*

Tried to go on and play, said I had to verify account, got taken to another site which is charging £1.95!!  I feel like I’ve just wasted £2.99 for a game I can’t even get onto never mind playing.

### 4/5 — Now being used in pubs

*2022-06-11, version 2.7*

Great app. Easy to use. Seen being used in pubs with iPad fixed next to board. Needs option to delete a leg in history. Refresh or update needed by developer please.

### 1/5 — Bluetooth keyboard

*2022-04-13, version 2.7*

Does not support bluetooth keyboard.

### 1/5 — んー

*2021-09-21, version 2.7*

カウントアップとか追加して欲しいわ〜

### 4/5 — Good - but could do with an update

*2021-05-06, version 2.7*

Excellent app, but showing its age a bit. I really like the ability to take on a virtual opponent and the ability to use the app for a game with your mates. But please add an option to play by sets instead of just legs. And then maybe save/export the averages and scores. 

Both of these features are on the windows version, but lacking here. And the ability to have more control over rotation, font sizes etc would be nice too. 

But, besides that, it's good!

Really good that the app runs on older IOS versions too.

### 4/5 — Klare Empfehlung

*2021-01-15, version 2.7*

Sehr gute App. Vielleicht könnte noch eine Spracherkennung hinzugefügt werden, dann wäre sie perfekt. Dann wäre man das lästige Eintippen los

### 1/5 — Two notes

*2021-01-01, version 2.7*

1. Cannot play on-line in application (only in Safari). 
2. Cannot log in to my account (once again only in Safari). 
Do you plan to extend the application? Any update?
