The tablets, the group chats, the game accounts, the wifi that buckles at 7pm β family tech is not about being the tech police, it is about being the calm grown-up in the room. These tools budget screen time by age, size your data plan, time device upgrades, set parental-controls priorities, check social-media readiness honestly, plan phone-free zones and school-night wind-downs, and build the family contract that turns arguments into agreements. Warm, practical, educational only — no shame, no panic, no guarantees. The full detailed report costs less than a coffee: $2.95.

Children's devices die differently from adults'. The usual failure is not obsolescence but physics β a dropped screen, a battery that stops holding charge, a port that stops charging β which makes the repair-versus-replace decision mostly simple maths rather than brand loyalty. The honest rule of thumb: if a repair costs 40 percent or more of a replacement, replace; if the battery is genuinely worn, the device is living on borrowed time no matter how new it looks; and a five-year-old device is old in child-device years even when nothing is broken, because security updates stop and apps outgrow it. This calculator weighs the device's age, its battery health, any repair quote and the replacement cost into one of four honest answers β replace now, replace within a few months, repair once, or keep going β with the reasoning in plain language, plus the family-policy questions that prevent the 'everyone else has one' arms race.
Decide whether a child's device is worth repairing, worth one more year, or genuinely due for replacement β the battery and age signals, the honest repair-versus-replace maths, and the upgrade conversation that does not become an arms race.
It is the widely used rule of thumb because repairs do not extend a device's life by much: pay 40 percent of replacement cost to fix one failure and the next failure is usually close behind. Under 40 percent, a single repair is often the honest value call.
Around five years, even when it still works: security updates stop, apps outgrow it and school platforms quietly drop support. Battery wear usually makes the decision for you first β a battery below roughly 30 percent of original capacity is living on borrowed time.
One family's 'too slow for Dad' is often a younger child's perfectly good first device with a fresh battery. Before buying anything new, check whether the 'new' device can actually be a hand-me-down from a grown-up β it is the same decision viewed from two ends.
Every tool answers instantly from our own knowledge and calculators β no AI wait, no account. The honest starting point: there is no single right answer for any family, and every child develops at their own pace. These tools give you the commonly used age-based guidance, the plain maths, and the next step β never shame, panic or pressure. Everything is educational general information about family tech habits, not medical, psychological, legal or financial advice and never a guarantee of outcomes. If a child is in immediate danger, contact your local emergency services right away β no tool here replaces that. Nothing you type is stored. Want the deeper, personalised version? Each tool has a $2.95 full report.
