DataMan - Data Usage Widget

とっても使いやすいアプリです！

安装收了0.99，然后如果想分卡管理，又需要订阅……

I should have read the description better. I don’t care about cellular usage. I work at a site for an extended period of time and we have Starlink. Each person is granted 3gb of data each day and you basically get in trouble if you go over. So I was hoping to be able to monitor WiFi usage and be able to set a daily alert once it reached a certain amount.

2GB以上のズレは擁護のしようがないでしょう。

The app works well with intuitive settings. Simple view that allows for a quick view on the status of your data.

A subscription to change billing periods? What a joke.

I like knowing I did not go over the cell limit.

UPDATE in response to developer: Thanks for the reply, but I have a screenshot of the pop-up triggered when I tapped “Font.” It promoted a Bonus Gift with Winter Wonderland and DONKEY Bounce — clear game content inside a paid app. Whether technically an ad or cross-promo, it’s irrelevant — it didn’t belong there and disrupted use of a utility I paid for. Also, your claim that the subscription model is clearly stated on the product page is weak, to put it generously. At no point was it made obvious that $0.99 only unlocked a crippled version, with nearly everything useful locked behind a second payment. That’s the problem — not privacy, not ads per se, but a misleading upsell loop in a paid download. Please just own the issue. It’s not about technicalities — it’s about trust. ----- I paid $0.99 thinking I was unlocking a full-featured data tracker. Instead, I got a barebones version with basic visuals and no real utility. To access what most people would reasonably expect from a paid app — like usage history, push alerts, multiple plans, or billing period customization — you have to subscribe again for $0.99/month or $9.99/year. Even worse, I got hit with a pop-up ad promoting unrelated games. In a paid app. That’s unacceptable. There was no clear indication upfront that the $0.99 purchase was just a teaser. It feels deceptive — a bait-and-subscribe model pretending to be a one-time paid app. Requesting a refund. If you’re looking for a trustworthy data tracker, look elsewhere unless you’re prepared to pay twice for basic functionality and still get ads.

Data man used to be great. Now the developers are moving previously available features behind a subscription paywall. Considering I was an original purchaser of this app, I find this move sleazy. Stay away from this app until they remove this. I don’t mind subscription services when they add capabilities, but you don’t remove them to add value to your subscription. You’ve lost me as a customer.

App doesn’t track data properly. Purchased this app at inception with themes, etc; now there’s a subscription cash grab 😡.

I installed DataMan to help guard against overage charges. It consistently shows I’ve used much less data than my carrier says. As of right now, my carrier indicates I’ve used 75% of my monthly limit. DataMan says 46%
