Track shared data usage for two with DataMan Pro

I installed DataMan Pro on my iPhone on January 2nd. While it was slightly uncomfortable ditching my unlimited (grandfathered) data plan from Verizon Wireless when I upgraded my phone, this app makes it a breeze to track my cellular data usage.

From left to right, and top to bottom:

  1. Current usage from this month
  2. Smart Forecast estimates usage for the rest of the month1, while the Balance displays how much cellular data I can use for the rest of the day.
  3. Stats: Usage by day
  4. Stats: Usage by hour
  5. Settings > Data Plan
  6. Settings > Data Plan > Add Usage
  7. Stats: Usage by month

Setup Tips and Observations

Data Plan — Review a few monthly statements. If your billing cycle starts on the same day every month, use the Monthly plan type. (e.g. 14th of the month)

For Data Cap, I just switched it from 1,000 MB to 1 GB (screenshot not shown) because 1 GB = 1,024 MB. Every bit helps!

Add Usage — To start accurately, log into the account with your service provider to verify your current data usage.2 Add the largest unit byte (whole number), then convert the decimal (probably from MB to KB) to add that last portion.

Multiple people — Amy and I share 2 GB of data, so we’re splitting that in half for each person.

Notifications — DataMan Pro includes push notifications at four configurable thresholds (called Usage Alerts). The defaults are 50%, 70%, 90%, and 100%.

Verizon Wireless can send email or text notifications when you reach certain preset thresholds (50%, 75%, 90%, 100%). I’m going to disable them because they reflect shared usage. We’re only concerned with individual usage.

In context, if I’ve used more data than Amy in a month, it’s up to me to ease up. She shouldn’t stress about it.🙂

Turn off Percentage Badge — If you’ll primarily rely on push notifications, you probably don’t care to see the percentage badge on the app icon, so you can turn that off in Settings > Advanced.

Interesting trends — When I’m home for most of the day, which is usually the case, I don’t use much cellular data.

However, when I’m out and about, Rdio, Day One, and Tweetbot can use up quite a bit if I’m not careful.

I’ve since disabled cellular data for the following apps in iOS 7 (Settings > Cellular):

  • Rdio
  • Day One
  • App Store
  • Netflix
  • Newsy
  • Scanner Pro
  • TuneIn Radio

Quirks

I always forget:

  • Swipe left goes to Settings
  • Swipe up displays your data usage over time.

Conclusion

I’m blessed to be able to work from home with a fairly solid internet and Wi–Fi connection. When not traveling, I don’t need to pay another $10/month for another 2 GB of shared data.

DataMan Pro will help us stay strong or realize when it’s time to fork over some extra cash. I gladly paid $4.99 for DataMan Pro, and will buy a second copy for Amy’s iPhone.


  1. In other words, if I don’t change anything with my service provider or data usage habits (like disabling cellular data for certain apps), I’ll use too much data on my account. With Verizon Wireless, overage costs $15 per GB. 
  2. Note the timestamp. That doesn’t update in realtime, so you may need to check several times and make multiple adjustments with Add Usage until it matches up. After that, DataMan should match exactly with your service provider. Should. ;)
