With tools to measure tide set and interpolated rate. The nearest Dover HW time to the actual time is selected from the database and the relevant streams chart is displayed, together with the time period for which the chart is valid. As the time moves to the next valid period, the relevant hourly chart is auto displayed. The app defaults to Local time, however UTC time can be selected if preferred. * Swiping on the chart, displays the next or previous tidal hour chart. * Whenever the chart displayed is valid at the current time, the validity period is displayed in green. * Pinching the screen zooms the chart * Tapping the location button shows your actual boat position on the chart. Select 'Channel Islands' or zoomed 'Alderney' streams chart, from the segmented control. Select the rate tool to auto calculate the interpolated tidal rate when in between neaps and springs. Select the 'Set' tool to measure the precise true course of any tidal stream arrow. (in-app purchase) Select the 'CTS' tool to calculate a Course to Steer. (in-app purchase) The app automatically selects the nearest Dover HW time of the day, but if you want to see data for the next or previous HW of the day, swipe forward or back to advance the tidal hour. For forward planning, tap on the date to select a different date, whereupon data relevant to that date will be displayed. ## iStreams Channel Islands Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple124/v4/e8/93/ef/e893efbd-4cc8-f6fa-2a72-01c05f0c06c6/pr_source.png/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/bd/f7/86/bdf78625-2edf-79f5-6be2-137be23ac4dc/c4d49077-2f8e-47cf-bd6b-c66fd343d954_NP264_11_Pro_Max_slides.001.png/1242x2688.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/90/c5/59/90c5594b-22d1-5f33-27eb-3d7c30bc4039/bacd3537-d459-40e1-8e99-09ab30c185de_NP264_11_Pro_Max_slides.002.png/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/7c/e6/77/7ce67745-4a79-f62c-961a-8f7269d0ab4a/83fd4aeb-3f81-455d-8b9b-352001484a98_NP264_11_Pro_Max_slides.003.png/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/f8/8e/d0/f88ed04b-9aea-796c-6fcc-3468cebdb8c2/a7dc5d94-b9d8-4970-b242-095e5b41cf50_NP264_11_Pro_Max_slides.004.png/1242x2688.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/3a/c2/4d/3ac24dcb-c03d-f8e8-d3da-90b784e37a0f/096b32e9-b232-4418-a30e-17bcb39d574d_NP264_11_Pro_Max_slides.005.png/1242x2688.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/1f/8a/47/1f8a478e-4f1b-a658-6fe2-9c17b0817918/1b4324ed-f70b-4223-a238-560b4d5d2e59_NP264_11_Pro_Max_slides.006.png/1242x2688.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/89/79/2a/89792a78-1635-daa4-5c58-00da65f898a7/8af8dcba-b5fd-4924-9a06-29bc198e9d6f_NP264_11_Pro_Max_slides.007.png/1242x2688.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/b0/73/ba/b073ba31-b43b-9779-6d2e-9db95405468f/2b7891a5-2529-4b3b-b506-5d89d8dda3b4_NP264_11_Pro_Max_slides.008.png/1242x2688.png) - [Screenshot 10](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/0e/f0/2e/0ef02e5d-bd33-786e-6f33-1bbe8d02b4e8/34ecd0e1-6ed8-4e78-8220-20e9330f1c58_NP264_11_Pro_Max_slides.009.png/1242x2688.png) ## iStreams Channel Islands Rating Breakdown in United Kingdom - 5 stars: 0 (0%) - 4 stars: 1 (50%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 1 (50%) ## iStreams Channel Islands Reviews in United Kingdom ### ****- "Good App" The app works well - I had a bit of problems getting the actual year on all on my devices (ie iphone and ipad) but the developer was very responsive and equally helpful in overcoming that issue. I would recommend istreams. -- Disappointment 02654, 2023-09-11 ### *---- "Inaccurate 2018 data" Old data don’t rely on this apps information -- Boat guy47643, 2019-05-17 [View all iStreams Channel Islands reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## iStreams Channel Islands In-App Purchases | Item | Price | |------|-------| | 1 Year Subscription | £4.99 | | 1 Month Subscription | £1.99 | | Unlock Set tool | £1.99 | | Unlock CTS tool | £3.99 | | 6 Month Subscription | £2.99 | | NP264 Unlock CTS tool | £3.99 | | NP264 1 Month Subscription | £1.99 | ## Apps Similar to iStreams Channel Islands -
