Was reliable, now it loses historical data

Loses historical data after automatic reset of the plan, either on cellular or wireless. Happened to me on iPhone and iPad and started a couple of months ago. Might be related to manually setting data.

Notifications on automatic reset of plan sometimes dont show up in notification view.

Wifi data counter may be off 5-10% compared to two other data tracking apps I use, which show the exact same wifi traffic.

Features are okay, but the UI lacks:
- No iPhone 6(s) (Plus) support, just inflated fonts.
- Always changing screen to either cellular or wifi view, which can be set in settings, but no keep-the-view-as-is
- Awkward way of setting billing quota in settings: no done or enter

I wish custom plans or counters would temporarily disable normal tracking. Also no history for these plans.
