A deposit savings tracker that also watches the mortgage market
Track your house deposit against a target date that moves with every payment, and see what rates in the band you are heading for are doing. Two jobs, one app, no bank connection.
Quick answer
Theo is a deposit savings tracker that measures your progress against a target date that responds to what you actually save each month, and monitors more than 100 UK lenders every weekday so you know what the mortgage market is doing while you save.
It does not hold your money or connect to your bank. You keep the deposit wherever you have chosen, and Theo runs the plan around it.

An example plan
April 2031
31% of a £40,000 deposit saved. £27,750 still to save at £500 a month, 56 payments left, next milestone a 5% deposit.
A deposit savings tracker where the date does the work
Pay your planned amount and the date holds. Pay more and it moves closer. Miss a month and it slips, immediately and visibly. That feedback is what keeps a two to five year plan alive.

| Loan to value | Average 2 year fix | Average 5 year fix |
|---|---|---|
| Loading | ||
| Loan to value | Deposit | What it usually means |
|---|---|---|
| 95% LTV | 5% deposit | The smallest deposits, the narrowest choice and usually the least competitive pricing. |
| 90% LTV | 10% deposit | A common first time buyer landing point, and where choice first widens noticeably. |
| 85% LTV | 15% deposit | Often where mainstream lender competition starts working in your favour. |
| 80% LTV | 20% deposit | Another meaningful threshold. Crossing it can matter more than the sum suggests. |
| 75% LTV | 25% deposit | Where much of the sharpest mainstream pricing sits. |
| 60% LTV | 40% deposit | Rare on a first purchase, but usually home to the very best pricing. |
A deposit savings tracker tied to your mortgage

Why a deposit savings tracker has to watch rates too
Savings trackers know the money and nothing else. They will tell you that you have saved £18,000 of £25,000, and nothing about what that buys you when you borrow. Mortgage apps know the market, but are built for people who already have a mortgage. So the person who would benefit most from a year of watching the market, someone about to make their first and largest mortgage decision, is the one nobody is watching it for.
How the deposit savings tracker works
You enter the price you are aiming at and the deposit percentage you want, and Theo turns them into a figure, a monthly amount and a date. Each month you log what you actually saved, and the date recalculates in front of you. Milestones are set at the deposit levels that change your mortgage options, so the final stretch is aimed at a threshold rather than a tidy figure. While you save, Theo checks 100+ UK lenders every weekday and shows how pricing in your band is moving.
Why a saver needs market alerts
If you have watched pricing for a year, you know whether the deal you are shown on the day is good, ordinary or worse than a month ago. Theo tracks lender repricing alongside swap rates, inflation and Bank of England decisions, the forces that move fixed rates before they reach the shelf, and follows the band your deposit is taking you towards. See mortgage rate alerts for how alerts work.
What is free and what is Premium
The deposit savings tracker is free: a target from a price and percentage, a date that moves with every payment, monthly check ins, milestones tied to loan to value thresholds, a check in reminder, and Market Signals showing daily lender moves. Premium, at £9.99 a month with a free trial, adds the what if simulator, full month by month history, editing past check ins, multiple property plans, and personalised rate alerts with deeper market intelligence. Pricing can change, so check the app store listing.
What it does not do
It does not hold your money or pay interest, so the deposit stays where you put it, often a Lifetime ISA for eligible first time buyers. It does not connect to your bank, so there are no automatic round ups; if you want automated saving, use an app built for that alongside it. It cannot promise a rate, and it is not advice: when you are ready, speak to a qualified, FCA-authorised adviser. Theo is on iPhone and Android.
