Short answer: if you have one usable hand, the problem is that a phone takes a hand to carry and a hand to use, and you only have one. A Keebos crossbody case carries the phone on your body so your hand is free, and the elastic finger strap lets you hold it without gripping. $49.90, free US shipping, 30 day money back guarantee.
The One-Handed Problem
Phones are designed on the assumption that you have two hands: one to hold the phone, one to operate it. Take one away and almost everything gets harder in the same way.
You cannot carry it and open a door. You cannot get it out of a bag while holding anything. Putting it in a pocket means the pocket on the side you cannot easily reach. And every time you want to type, you are balancing the phone on your fingers rather than holding it.
None of that is about the phone being difficult. It is about the phone needing a hand you do not have spare.
Who This Is For
The specific reason varies, and the practical problem does not.
- A broken arm, wrist or collarbone. Six to eight weeks in a cast or a sling, usually with the dominant arm out of action because that is the one you put out when you fall.
- After shoulder or hand surgery, where you are told not to use the arm at all for a period.
- After a stroke, where one side has limited or no function, sometimes permanently.
- Amputation or limb difference, whether from birth, injury or surgery.
- On crutches, where both hands are technically working but both are committed to moving.
If you are in the last few weeks of a temporary injury, the case is still worth it, because the strap keeps working long after the cast is off. If your situation is permanent, it is worth being clear about what this does and does not do, which is below.
What Actually Helps, Specifically
1. You never have to carry it
This is the main thing. On an adjustable strap the phone hangs on your chest or at your hip. It is not in a hand, not in a bag you would have to open, and not in a pocket you cannot reach. Your one hand stays available for doors, rails, crutches, a coffee, or the child you are holding.
2. You can hold it without gripping
Behind the wallet is an elastic finger strap. You slide two fingers under it and the phone sits secure against your hand with no squeezing at all.
That matters more one-handed than it sounds. A pinch grip on the edges is an active muscle contraction you have to maintain, and it is the hold most likely to fail when you are tired or your hand is doing something else. Hooking two fingers is passive, and it frees your thumb to actually move around the screen instead of being part of what holds the phone up.
"Amazing way to carry your phone. The wallet is underrated, keeps my cards safe and there is a finger strap that makes it easy to hold it in one hand."

3. It does not need two hands to put on or take off
The strap adjusts by pulling two cords. No buckle, no clasp, no threading anything through anything. It unclips from the case in seconds when you want a plain phone case.
This is where a lot of otherwise sensible products fail: a solution you cannot operate one-handed is not a one-handed solution.
4. Your cards come with the phone
The sealable wallet on the back holds up to 6 cards plus cash. Getting a wallet out of a bag and a card out of a wallet is a two-handed job, so having your ID and a card attached to the phone removes one of the more annoying daily problems, especially at a checkout with a queue behind you.
5. It does not get dropped as far
Doing anything one-handed means more fumbles, and phones get dropped in the handover moment. Attached to a strap, a slip is a swing rather than a fall.

Wearing It With a Cast or a Sling
One practical note, because it comes up. Wear the strap on the side of your working arm, not over the injured one, and set it a little shorter than feels natural so the phone sits high on your chest rather than swinging into a cast or an arm sling when you walk.
The strap adjusts along its full 54 inches by pulling two cords, so you can change that with one hand while wearing it.
What This Is Not
Worth being straight, because buying the wrong thing when you are already dealing with an injury is a genuine annoyance.
- It is not an adaptive or assistive device. It is a phone case with a strap. It makes no clinical claims and it is not a substitute for equipment your occupational therapist recommends.
- It is not a grip aid for severe hand weakness. The finger strap helps, but if your difficulty is that you cannot close your hand at all, a case built around a fixed finger loop may suit you better.
- It is not rugged armour. There is drop protection, but if the phone is taking repeated hard falls, a heavy-duty case is built for that.
What it does is remove the need to have a hand free for your phone.
What It Costs
- Crossbody phone case with wallet and strap: $49.90. Includes the fitted case, the adjustable 54 inch strap, the sealable 6 card wallet and the elastic finger strap.

One-Handed Phone Use: FAQ
What is the best phone holder for a one handed person?
One you wear rather than carry. A crossbody case on an adjustable strap keeps the phone on your body so your working hand stays free, and an elastic finger strap on the back lets you hold the phone by hooking two fingers under it instead of gripping the edges. Check that the strap adjusts without a buckle, since anything needing two hands to fasten defeats the point. The Keebos version is $49.90.
How do you carry a phone with a broken arm?
Wearing it is the simplest answer, because a cast or a sling takes away the arm you would normally use to hold or retrieve the phone. Wear the strap over your working shoulder rather than the injured side, and set it short so the phone sits high on your chest instead of swinging into the cast.
Is there a phone case for people with one arm?
A crossbody case works well, because the problem is not the phone itself but that a phone needs a hand to carry and a hand to use. Worn on a strap it needs neither until you actually want it, and the finger strap means you can hold it without a full grip. The strap adjusts and detaches with one hand.
Does it help after a stroke?
Many people use one for exactly that reason. With limited function on one side, the phone is the thing that constantly needs the hand you are also using for balance, doors and everything else. Wearing it removes that conflict. It is not an assistive device and it is not a substitute for what your therapist recommends.
Can you put it on and take it off with one hand?
Yes. The strap has no buckle or clasp. It goes over your head like a necklace, adjusts by pulling two cords, and unclips from the case in seconds.
Will it fit my phone?
Fitted cases are made for iPhone, Samsung Galaxy including the Z Fold and Z Flip, and Google Pixel. Check your exact model in Settings before ordering. If your phone is outside those ranges, or you already use a grip case that suits your hand, the $34.90 universal strap attaches to any case.
Is it worth it for a temporary injury?
Most broken arms mean six to eight weeks in a cast, which is long enough to be worth solving. The strap also detaches afterwards, so the case carries on as an ordinary phone case once you have healed rather than becoming something you no longer need.
