The actual time between beeps differs from the displayed time by a few tenths of a second, which is a bid deal for short times. A par time of 1 s is closer to 0.8 s, for example.

So I love this app, works great for dry fire practice. Only thing I'm wondering is why it's so expensive for such a simple cut and dry app. Please add some features to make it worth the price. At the moment it feels like it should cost $0.99. The ability to drag and drop stings would be nice, let's say I want to add a new string to the BEGINNING of the drill. Right now that requires making a new string at the END of the drill and then changing the repetition and par time for every other string before it in the list. Also, some way to sync or export/import drills would be nice. Would be a hassle to rebuild a long list of drills when buying a new phone for example. Would be great to import training drills from other users as well. Honestly, for $8.99, I feel this app is missing features. Again, it works great, it's just so simple that it should be much cheaper. I mean, it doesn't even double as an actual live fire timer, come pre loaded with popular drills, or have any features of the like.

This app does not come with a lot of features but it is simple and effective and does what I needed to do. You can easily make new drills and save them. Each drill consists of a number of strings and each string has a number for a repetitions. For each string you set the par time. With a simple click of a button you can adjust all the par times in the drill as you improve. Each drill is saved using the par times you have set. This app is easier to use for dry fire practice then a shot timer. I recommend it.

The pros: Simple to use and I like how you can save different drills. For example I can set up 5 different times for bill drills that I use for different yards. The Con: Major complaint is the time is off. It’s much faster then a actual timer. Probably off by .2 or more. Also if you want to stop you need to go back to the beginning. I like to set up a drill and do maybe 10 reps and then bring the par time down and continue. The problem is if you want to stop you have to start from the beginning.
